1) What you grow in your farm,  2) The proper acclimatization of the greenhouse for maximum growth including warm temperatures and ample sunlight or grow lights.

2) The average family of five consumes one head of lettuce per day for salads, garnish or sandwiches. The lettuce is planted on 8-inch centers in the Grow Tray. For example, the lettuce (example), needs approximately 30 to 40 days from ‘planting to harvesting’ which means there will be 40 lettuce plants in the Grow Tray at all times. 40 lettuce plants require 27 square ft of grow space. Each time a lettuce plant is harvested, a new seedling is placed in the same space to be ready to harvest in 40 days.

Here is the trick that is the hardest for new Portable Farmers to grasp: THINK AHEAD AND PLAN LIKE A FARMER! Refrain from planting all of the space at once.  That is 27 square feet of open space for lettuce will tempt you to fill it up. Don’t do it. Plant a new baby lettuce plant every day into the gravel.

Quick Read: What Can Portable Farms Grow?

Primarily, Portable Farms® Aquaponics Systems are capable of growing green table vegetables year round if the interior temperature of the greenhouse ranges between 70 degrees F and 100 degrees F and receives a minimum of six hours of direct sunlight per day or with the use of grow lights during winter months to extend the grow day (generally from 4:00 PM to 7 PM each day).

Peppers, cucumbers, tomatoes (blossoming plants) grow best in warm months (to avoid blossom drop) when average temperature within the green house is 70 degrees F with extended sunlight by use of grow lights.

Here are a few of the table vegetables that can be grown in a Portable Farms® Aquaponics System:

    • Swiss Chard
    • Basil
    • Kale
    • Mustard Greens (what we call Wasabi Lettuce – hot hot hot)
    • Dozens of varieties of Lettuce
    • Dozens of varieties of Asian greens
      Boc Choi
    • A wide variety of herbs
    • In warm climates or acclimatized greenhouses with extended days of sunlight (grow lights), blooming plants grow well in aquaponics including beans, peas, tomatoes, peppers, cucumbers and zucchini.
    • Starting with USDA data for a healthy diet and accepting that most carbohydrates will come from grains and root crops, the table vegetables for one person can be grown in 25 sq. ft of aquaponics grow tray space. So, a family of eight will need 200 square feet of grow tray space or a Grow Tray 5′ wide by 40′ long.
    • The major food groups that are not recommended for Portable Farms® are root vegetables (carrots, potatoes, onions, etc.) and corn, wheat, soy or rice. Perennial plants (strawberries, blackberries, asparagus, etc.) are not recommended because the plants are dormant 9 months per year and do not produce harvest-able food year-round.
    • Plus, fish tank-raised fish are vital to aquaponics but unless you are operating a commercial farm with several tanks, they will not supply a steady supply of tilapia fillets for a family of eight. We recommend Oreochromis Mossambicus Tilapia. It’s a mild white fish that we harvest in 7 to 9 months when they weigh 1.25 pounds and produce 2 four-ounce fillets. The fish are a bonus in aquaponics that are primarily used to provide nitrogen to the plants and other nutrients.

Tilapia – The Fish That Fertilizes Plants in Portable Farms Aquaponics Systems

Tilapia – The Fish That Fertilizes Plants in Portable Farms Aquaponics Systems
– by Colle and Phyllis Davis

One of the most commonly asked questions we receive is concerning
the fish that we use in Portable Farms®, “Why Tilapia?'”

In the US, please check with your local Fish and Wildlife Department in your State and see if Tilapia are legal in your area.

It generally takes between 7 and 9 months for a tilapia to grow to maturity and we harvest them then at 1.25 lbs (approximately) which yields two four-ounce fillets.

Tilapia is still our champion and will probably remain so for a long time:
Tilapia are considered a fresh water, warm water fish.’ The plants grown in aquaponics systems grow faster in a warm environment, which requires warm water flowing through the systems. Plants do best at 73° F no matter where they are in the world. They may grow faster or slower in warmer or cooler temperatures, but they grow best with a leaf surface temperature of almost exactly 73° F. That means that the fish in the system need to love and enjoy warm water. Please note, different countries have different choices for their aquaponics systems with fish that are ‘fresh water, warm water fish’ other than tilapia. For example, in Australia we’re told they favor using barramundi, silver and golden  perch, and catfish. Portable Farms Aquaponics Systems favor using tilapia.

  • Most trout/salmon do not like water over 60° F at which point they begin to experience stress and become susceptible to diseases above this temperature level. This means either the water must be cooled and heated each cycle, or the fish or the plants will be unhappy and not grow well.
  • Trout/salmon are also carnivores and are grown best on animal protein. Commercial trout chow contains fish meal as the protein source and that fish meal is from ocean harvest fish, depleting the ocean fisheries.
  • Catfish, which was our personal first choice, have a different problem. The fry or fingerlings are only available three months of the year (May, June, July) so there is no way for farm owners to constantly restock their fish tanks. Catfish grow quickly, they like warm water, they will eat almost anything, they taste good and are a hardy fish. But, stocking off season is impossible.
  • Perch are carnivores and eat bugs, crayfish and other animals to grow. These are tough to get in the winter time unless you grow them inside for some other purpose. Perch food is tough to get almost any time of the year. Perch taste sweet and are easy to work with but are difficult to find food for them.
  • Crayfish and freshwater prawns are cannibalistic and need to have separate ‘apartments’ built in the tanks so they don’t eat each other. They are sometimes used in the tanks with other fish to clean up the bottom of the tanks. They are very hardy, but the housing for them is a problem.

That leaves the incredibly, tasty, hearty and adaptable Tilapia. They are very easy to prepare, taste great, grow quickly, and are available year round. They will eat and prefer plant protein and are very hardy. They prefer a water temperature in the low 80° F’s, the water can be fresh water, brackish water or even salty water, and they do just fine. They will thrive in water that can be dirty looking and still grow and be ready for eating almost anywhere in the world. Of course, our newly configured Portable Farms CAD pumps remove all sediment from the tanks and they swim in clear, clean water that turns over at least twice per day.

Grow and Sell Food with Commercial Aquaponics

Grow and Sell Food with Commercial Aquaponics 

Becoming a commercial aquaponics farmer requires the technology information, plans, the permits, site preparation, the inspections, the ordering of the greenhouse and the thousands of small and large steps all of which are necessary. But once started on the site development and the assembling of the greenhouse everything becomes REAL and moves all the plans into actions. This is always a very exciting time for our new customers and brings a sense of ‘this is real’ for everyone involved.

All construction projects (large and small) require planning and careful execution to build that dream to completion. Every new building is surrounded with a glow and an energy that is very difficult to describe and yet everyone knows the feeling of accomplishment and the energy that result when carefully executive plans come together and begin to materialize.

Lettuce grown in Portable Farms uses 95% less water than traditional agriculture and grows in HALF the time as soil-grown lettuces.

Dan Burden, AgMRC Content Specialist

D. Allen Pattillo, Department of Natural Resources Ecology & Management,
Iowa State University; North Central Regional Aquaculture Center (NRAC)

This closed-loop system has many advantages over conventional “open-loop” crop production systems:

  • It uses approximately 10% of the land area and 5% of the water volume required by conventional vegetable crops.
  • Due to less water and land use, aquaponics is perfect for highly efficient use of existing space or for special applications like intensive urban gardening.
  • Crop production time can be accelerated.  For example, butterhead lettuce varieties can be produced in about 30 days, instead of the typical 60-day growing period needed for conventional production.
  • Production can occur year-round under a greenhouse or in a temperature-controlled enclosure.  This allows producers to market fresh produce during seasons when trucked-in produce is at their highest seasonal prices.
  • Aquaponics is an adaptable process that allows for a diversification of income streams.  High-value herbs, vegetables, and leafy greens, as well as fish, crayfish, worms, mushrooms, and a number of other crops may be produced, depending upon local market interest and the interests of the grower.
  • These systems allow agriculture to take large innovative steps toward environmental sustainability.  Because these are mostly-closed-loop systems, nutrient effluent leaving the facility is virtually nonexistent.  Additionally, fish, plant, and other waste solids may be captured and converted into value-added fertilizer products for wholesale or retail sale.
  • Growers can start small, with minimal investment, perhaps using scrounged materials to see if the venture is “right for me,” then scale-up as markets and expertise develops.

A small backyard aquaponics installation is not a good investment from a business standpoint. For example, if you were interested in growing and selling the food from your aquaponics system, the ROI (Return on Investment) would be 5 to 10 years or even longer. It’s a wise move to invest money where you receive a faster rate of return. On the other hand, the value of your installation increases each year even if you sell none of the production

Backyard Aquaponics Systems

Those who buy a Portable Farms Aquaponics Course and Kit or build their own style system are interested in the following factors.

  • They want to learn about aquaponics growing. [Many have an interest in expanding their backyard farm into a larger operation with the idea of selling their produce and fish. For those, we recommend a minimum of ten Portable Farms® modules 5’x40’ or 6’x32’ to create a reasonable ROI for their time and investment.]
  • They want to involve family members in a hobby that teaches everyone the process of growing vegetables and raising fish.
  • They are interested in growing fresh, healthy and delicious food year-round to become more self-sufficient and sustainable.
  • They want to share their interest in aquaponics with family, neighbors and friends. Did someone mention bragging rights? Yes, they did.

The Economics of a Family-Sized Aquaponics Greenhouse

  • The highest cost of a backyard yard aquaponics system is the greenhouse structure. If year-round production is the goal, then a climatically adapted structure will be 60% to 70% of the total cost. Building a food-protection facility for your family is expensive, but the payback is worth the investment.
  • The cost of a head or bunch of lettuce in the summer is low because it is readily available from many sources. The cost of that same head/bunch of lettuce in the winter can be up to three times the summer cost.
  • How valuable is having your produce fresh and available year-round? What dollar value is there in knowing the routine is to plant, harvest, and feed the fish—no weeding, no spraying, no insects, no rotting vegetables.
  • The ROI on a backyard family aquaponics farm is difficult to measure in terms of money. It is easy to understand the value of enjoying the best food on the planet readily available. A small solar electrical system and some supplemental heat means you can survive most disasters. There is a satisfaction in knowing you are providing for your family even in hard times.


Commercial Aquaponics Installations

On a larger scale, commercial installations (3,000+ sq. ft / 279 m2) have an ROI’s in the one-to-three-year range depending on these factors:

  • The successful operation of a commercial sized farm is dependent on the skill of managers and operators of the farm.
  • The choice of seeds and crops (vegetables and fish) they grow in their farms.
  • The marketing skills of the manager of the farms to sell and deliver the food to their customers in a timely manner so the food is harvested and delivered at the peak of perfection.
  • The success of the structure (greenhouse) to 1) maintain moderate growing temperatures, 2) provide safety and growing-level conditions within the farm to protect the plants from weather, birds, insects and other predators (squirrels, etc.), 3) a minimum of six hours of direct sunlight per day, 4) Plants can only utilize approximately 70% of direct sunlight. Shade cloth is vital for crop protection for UV and heat sensitive plants.

The larger the facility, the faster the payback. Several large installations will pay themselves off at a rate that allows the income to fund more installations.

Greenhouses to House Your Backyard Aquaponics System

This 10′ x 16′ greenhouse frame is large enough to hold one 5′ x 12′ grow table
capable of feeding two people table vegetables FOREVER.

There are thousands of articles and videos available covering building greenhouses. Pick one that works for your situation and the cost of building. Just the building cost will fall between US$1,000 to US$8,000. Some of this difference is in size, how well insulated it is, and the rest is how fancy you want to make it. The interior temperature needs to stay in the 40° F to 100° F range (4 to 40 C).

Assuming you are ready to build the greenhouse, the next step is where to place it. The building needs 6 hours of direct sunlight each day for the best results. Or you will need supplemental lighting to reach full production levels. Shade cloth is also necessary and made movable to maximize the growing season.

If you’re interested in a lean-to greenhouse on the side or back of your house, we’ve provided a link to a free plan and tutorial at the bottom of this page.

  • South of the 37th parallel latitude, (Mason/Dixon line in the US) the best results are realized using a north/south orientation of the long measurement of the building. This layout spreads the sun over the interior more effectively and makes the use of shade cloth more efficient.
  • North of the 37th parallel, it is best to use an east/west long measurement to build on. This layout allows for more insulated areas and better heating in the winter. It also makes cooling more efficient in the summer because of the prevailing wind direction.

The ROI on backyard aquaponics systems is immeasurable. They have an intrinsic value to you and your family. Knowing food is available, having some long-term storage foods as a backup, and knowing how to fix nutritious meals for loved ones brings peace and satisfaction in these troubled times.

12-Month Aquaponics Gardening in a Lean-to Greenhouse

12-Month Aquaponics Gardening in a Lean-to Greenhouse
By Colle and Phyllis Davis

Portable Farms Aquaponics System in Playa Rosarito Beach, Baja California, Mexico

Portable Farms Aquaponics System installed in this lean to greenhouse next  to a house in  Baja California, Mexico.

People are contacting us regarding 12-month aquaponics gardening in a lean-to greenhouse built next to their house. This article addresses the answers to their questions.

The ideal location to for your aquaponics installation may or may not be where you want to build it. We do not recommend areas that are shaded or in driveways or next to tall fences. Here is a list of requirements and suggestions for maximizing the location of your aquaponics system, so it receives the maximum level of sunlight to grow your food.

Here is a short list of considerations and suggestions to help you create an ideal place to install your greenhouse and build your aquaponics system inside that greenhouse.

  1. Find a place that provides your greenhouse six to seven hours of direct sunlight each day that shines directly over your Grow Table.
  2. The greenhouse should be orientated to maximize the sunlight and to minimize cold infiltration.
  3. Your greenhouse must have access to water and power.
  4. There must be proper floor drainage inside the greenhouse to keep floor dry.
  5. If possible, place your greenhouse on a concrete floor.

FREE DO IT YOURSELF PLAN: How to build a lean-to greenhouse

(*Link to this website at the bottom of this page. This website offers step-by-step instructions with great graphics that are easy to follow.)

Another possibility is to build a greenhouse along the side of your house or garage. We recommend consulting someone with an understanding of moisture flow before building a greenhouse attached to your house.

The requirements of an attached greenhouse need to have the following considerations to be effective:

  1. The greenhouse should have a south or southwest exposure.
  2. There should be no trees or large shrubbery nearby.
  3. It must have good drainage within the greenhouse. This is vital.
  4. While building your greenhouse, build a stem wall (short concrete or insulated wall on the wall of the greenhouse).
  5. Build your greenhouse on a concrete slab.
  6. Optional: Consider venting the greenhouse into your house in the winter as an inexpensive and pleasant addition to the air inside both the house and the greenhouse. The added moisture is welcomed but needs to be monitored to insure it does not promote mold. Venting the greenhouse into the house demands you keep your fish tanks and clarifiers clean to avoid a gamey smell.

Additional advantages of building mounted greenhouses next to your house or garage:

  1. They require less insulation.
  2. They are much easier to build than a traditional greenhouse.
  3. They are faster to build.
  4. You will get your aquaponics system up and running sooner.
  5. By building a door between the house and the greenhouse, you can have access in-and-out of the greenhouse.
  6. With an access door, you don’t have to go outside in extreme weather conditions.

Now, here are the disadvantages:

  1. Noise. The air pump can be noisy and may to be need to be installed in an enclosed box to quiet the sound.
  2. The fish waste can smell bad or at least be noticeable when being removed from the settling tank. This may or may not be a problem.
  3. There needs to be two separate exhaust fans. One fan for winter that blows into the house and the other to exhaust to the outside in summer.
  4. The height of the lean-to greenhouse may not be tall enough for good circulation and shading.
  5. Supplemental lighting will (most likely) be necessary in any kind of growing structure.

In most cases the advantages far out-weigh the disadvantages, however, please take the time to consult family members to get their input before proceeding.

The ideal situation includes:

  • A door (it may already be there) between the house and the greenhouse.
  • Water and power must be available without running new pipes or lines.
  • If possible, install your greenhouse in front of a large window to the house so you can admire your garden. Plan on installing the door and window (if they are not there) for best results.

Having the aquaponics system next to the house is smart, convenient, and creates both a unique awareness of growing things and a fabulous place to chill out. Spending quiet moments inside in a warm, moist greenhouse in cold weather is a perfect way to beat the winter blues.

If you have questions of how to build the aquaponics systems, please read the curriculum for Aquaponics University and sign up for the course. We will help you size your installation.


Get Rich With One Acre of Aquaponics

– by Colle Davis, Phil Estes and Phyllis Davis


GET RICH WITH AQUAPONICS WITH ONE ACRE OF AQUAPONICS but first, begin with one small aquaponics’ system to learn how to operate it and see if it meets your expectations. Even ONE 5×40′ MODULE that feeds eight people is a realistic experiment to ‘get your hands wet’ as you learn to grow healthy vegetables and raise fish.

With a ROI (Return on Investment) for a 10,000 square foot facility (one-quarter acre), over three to five years, and the possibility that by addressing a specific local market needed to produce a specialty green) crop such as kale, basil or bok choy, and reducing the ROI to less than two years, investors take notice. When a single commercial installation pencils out to yield a net-net in the low six figures and the output can match any wholesale supplier’s prices and still make money, serious investors are interested.

Commercial aquaponics installations are not subject to the normal vulgarities of the stock market, derivatives markets, political upheaval, drought, electrical outages, heat waves, unusually hot or cold weather or even state-sponsored corruption.

This comprehensive information about commercial aquaponics provides you will all the facts you’ll need to make an informed business decision about commercial aquaponics growing in controlled environment agricultural (CEA).

One module of a Portable Farms Aquaponics Syste

The most common request we receive from those who want to become commercial aquaponics farmers are from people who already have the land and want to install aquaponics installations on their property. Although they may own the land, they do not have the money to make a large initial investment.

One acre of flat, level land covered with four Portable Farms® Aquaponics Systems can make you a millionaire and with an ongoing income of over $300,000 from the full acre per year NET. To fund this size operation all at one time requires approximately US$1.2Million.

Here are several scenarios that demonstrate how to achieve this level of success is stages over time.

Oreochromis Mossambicus Tilapia. This is the male tilapia used in aquaponics systems in the Northern Hemisphere.

Everyone’s situations obviously differ from these proposed instances, but you can use these scenarios as examples and then adjust them for your unique situation.


• Land cost is not a factor – meaning the land is owned or leased at a low rate already.
• You are willing to invest the time to prepare a quality business plan before you begin.
• You have access to $200,000 of capital or the ability to borrow that amount.
• You understand the meaning of hard work.
• Marketing is a passion and a way of life for you.
• You or your partners have successfully operated a growing business for more than five years.

Five Suggested Scenarios and Options for Beginning your Aquaponics Business

First Scenario:

  • You already own the land.
  • The property has access to electricity and water.
  • The land is mostly flat and level.
  • While solar power and well water are options, they may come with additional costs.
  • Your land is located near your potential markets for selling your food, and you do not have the investment capital to begin the project.  In this first scenario, your land is not currently paying you anything in return, but you are paying property taxes on it, and there are other normal expenses that you incur by owning it.

(Brace yourself, this following suggestion may hurt . . .)

Sell enough of your land to fund the first acre or even the first 10,000 sq. ft. aquaponics installation. That way, you are investing your own money in your own aquaponics business and you are paying yourself back with interest. For example, the average size of currently owned acreage of those we have talked with, is 10 to 12 acres (the range is from 2 acres to several thousand acres). If a portion of this land was sold, even most of it, your new commercial aquaponics project could be at least partially funded from the proceeds.

Second Scenario: 

You may consider refinancing your land and using the proceeds to build the first aquaponics installation(s).

This may or may not please your banker, but he will enjoy being paid back in a few years.

Third Scenario:

Find some partners who agree to fund the aquaponics installation on your land. Be the ‘land guy’ and be willing to structure the deal so you are the last to be paid off. After all, it is your land and the installation is on your property and it will be producing income far into the future. You may even want to structure the deal to pay off your partners in total, first, and then you will continue to receive all the income for yourself.

Fourth Scenario:

If you don’t own the land, but you know someone who does own it, and you are willing to do all the work to make this project happen then consider asking them for permission for you to use one acre of their land for aquaponics installations in exchange for a percentage of your business profits.

You may also consider approaching several other investors to fund the installations and then you would provide the hard work of operating the commercial aquaponics systems. This is the hardest scenario to accomplish UNLESS you have a proven track record running a business.

Fifth Scenario:

Research real estate listings and find a few existing greenhouses in your area that area available to lease, and then install the Portable Farms Aquaponics Systems Modules to fit into the greenhouse(s). Then use this installation to generate the capital needed to finance the expansion of additional units on your unused property. The upfront cost of doing this is a fraction of the cost of building a greenhouse from scratch.

Okay, enough with the options, let’s get down to the numbers.

  • A single 10,000 sq. ft. facility can hold approximately 30 Portable Farms® Aquaponics Systems Modules costing from $80,000 to $100,000, installed.
  • The ROI can be from 2 to 4 years depending on your markets and the crops you choose to grow and sell.
  • Payroll for two full time employees to operate a single commercial PFAS Unit (30 modules)
  • The Net-Net for this example is US$100,000 per year

  • Four PFAS Units (120 modules) are needed to be a millionaire
  • Four PFAS Units will require approximately US$1,000,000 of initial investment.

To start, do your homework, complete your marketing survey, talk to a local casino, high-end restaurant and resort hotel chefs to see how much of their weekly produce they are willing to buy from you. Talk to at least TEN chefs, add the numbers of different vegetables they are requesting together, divide by two (this gives you the built-in expansion for your business) and design your installation to fulfill that amount of produce by the end of your first year of production.

Yes, it’s a LOT of hard work, focus, managing yours and/or other people’s money and a dedication to bring the finest food on the planet to your market that can make you a millionaire in a few short years, but like all growers and farmers will tell you, there is a great deal of hard work ahead. PFAS LLC’s Portable Farms® Aquaponics Systems technology offers one way to grow healthy food and profit from your hard work.

Commercial aquaponics programs will change the face of aquaponics, make their investors very happy, create jobs for thousands of people and equally important, provide the highest quality, locally grown food for the growing middle class around the world. The technology of aquaponics, especially as a viable alternative to long-food-miles groceries is finally becoming a part of mainstream thinking.

As the acceptance of aquaponics moves from fringe idea to proven commercial production, there has been a profound shift in those who are interested in applying the technology and how they are affecting the industry. Now the moneyed people (the serious investors), the visionaries with immense deep-pocket connections and the people who can make a difference in the world are stepping into the food growing arena as investors.

Aquaponics is at least 4,700 years old and has been practiced in various forms in many places in the world, especially where great amounts of food were needed for large for areas with large population and the land or water was limited. Maximizing the nutrient stream (fish effluent) is critically important when land is restricted. The use of animal’s waste to encourage the growth of aquatic plants and animals is an elegant solution to a wastewater management problem.

Modern aquaponics offers a locally based, extremely high yield, food production facility that also provides permanent full-time jobs for semi-skilled workers. When a concentration of modern aquaponics installations occur an increasingly sophisticated and broader administrative function is required to run them effectively.

Another benefit of these installations is the creation of many secondary jobs. These additional jobs normally add four to seven additional local positions in the support-function businesses.

What have you done to prepare you and your family if the coronavirus arrives in your area?

Is your family protected, prepared and ready to ride out the coming pandemic? There will be more and more deadly viruses in the future as climate change increasingly impacts the growing conditions in every area.

Advice from the US Center of Disease Control

    • Avoid close contact with people who are sick.
    • Avoid touching your eyes, nose, and mouth.
    • Stay home when you are sick.
    • Cover your cough or sneeze with a tissue, then throw the tissue in the trash.
    • Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.
    • CDC does NOT recommend that people who are well wear a facemask to protect themselves from respiratory diseases, including COVID-19. Facemasks should be used by people who show symptoms of COVID-19 to help prevent the spread of the disease to others. The use of facemasks is also crucial for health workers and people who are taking care of someone in close settings (at home or in a health care facility).
    • Wash your hands often with soap and water for at least 20 seconds, especially after going to the bathroom; before eating; and after blowing your nose, coughing, or sneezing.
      If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty,

Food safety and food security are growing concerns for people in all areas of the world should they become impacted by issues related to climate change, food distribution breakdowns or lack of affordable transportation to deliver food, or in this case, the spread of the coronavirus.

Double check your pantry and buy dried or canned foods that will prepare you to live under quarantine if you need to hunker down for a few weeks due to the spread of coronavirus:

    • Nuts, seeds and peanut butter
    • Distilled water
    • Powdered milk and powdered eggs
    • Fresh eggs
    • Coffee and tea
    • Canned tuna or other canned fish
    • Canned meat or canned poultry
    • Canned chili, canned soups
    • Flour and yeast to make bread, flour for pancakes
    • Dried potato flakes
    • Dried corn, grits, popcorn, cornmeal
    • Cereals, corn, rice, grains, oatmeal
    • Powdered drinks with Vitamin C included
    • Snacks including chips, cookies, protein bars, chocolate
    • Salt, sugar, spices
    • Cooking oil
    • Cheeses encased in hard wax

“Preppers” have a big-leg-up on this type of disaster. They understand there will come a time where each family is on their own and utterly dependent on what they have on hand and what they can produce. Your community may or may not be impacted by this virus, but you can prepare for any future events. The survival of you and your family depends on how well prepared you are for any eventuality.

Build a Portable Farms Aquaponics System to create FOOD SAFETY FOREVER!

WHAT IS MISSING IN THE LIST POSTED ABOVE? A Portable Farms Aquaponics System grows fresh vegetables and fresh fish! A climatically adapted structure with solar power provides a powerful and effective method of growing your own survival. Imagine a 16’ x 36’ (4.9m x 11m) can grow enough table vegetable for 8 adults forever. Children over the age of 11 are counted as adults.

Gardening is seasonal in temperate climates and dependent on weather conditions and storage facilities. A greenhouse ensures a year-round supply of fresh vegetables. An aquaponics system adds fish, a protein source, to the list of benefits. The greenhouse is also a wonderful place to relax and be in touch with living, growing things to refresh your soul.

Storing long term food supplies such as beans, wheat, corn, and other grains and insuring you can cook them is the first level. Growing your own food to ensure survival for extended periods of time or maybe even as long as you live is imperative. Preparing for long term chaos periods makes you less vulnerable to short-term disruptions. Think of this preparation as peace of mind insurance.


What May Happen – According to the US Center for
Disease Control (CDC) – Updated February 23, 2020

More cases are likely to be identified in the coming days, including more cases in the United States. It’s also likely that person-to-person spread will continue to occur, including in the United States. Widespread transmission of COVID-19 in the United States would translate into large numbers of people needing medical care at the same time. Schools, childcare centers, workplaces, and other places for mass gatherings may experience more absenteeism. Public health and healthcare systems may become overloaded, with elevated rates of hospitalizations and deaths. Other critical infrastructure, such as law enforcement, emergency medical services, and transportation industry may also be affected. Health care providers and hospitals may be overwhelmed. At this time, there is no vaccine to protect against COVID-19 and no medications approved to treat it.

Aquaponics Is a Perfect Match for Those with an Ambulatory Disability

Aquaponics Is a Perfect Match for Those with an Ambulatory Disability  LOVE TO GARDEN? But, can’t bend or stoop? Portable Farms® has a solution! 
– by the Inventors of Portable Farms®  Aquaponics Systems
Until now, ‘dirt gardens’ have not been an option for those with ambulatory disabilities because of their difficulty reaching down to the ground dig in the dirt to plant or weed their garden for long periods of time. For those using wheelchairs or for those unable to kneel for great lengths of time, gardening has been out of reach for them. But wait! We have a solution for all those with an ambulatory disability who love to garden that will satisfy their desire to plant, nurture and grow their own food: AQUAPONICS in a Portable Farms® Aquaponics System! One of the unsung advantages of aquaponics is the minimal care required in Portable Farms®! A Portable Farm requires only minutes of care per day to feed the fish, plant, care for, or harvest the plants in the waist-high grow trays. Plus, these grow trays can be designed specifically for those ambulatory disabilities. The height of the grow trays can be adjusted up or down to accommodate wheelchairs, those with braces, those using crutches and other disabilities. The aisle width can be modified, usually made slightly wider to accommodate those needing more space between the grow trays.

There are some instances where the food output or production from the installation is a secondary, albeit important, consideration. The extremely high therapeutic value of the greenhouse/growing environment is such that having the opportunity to be in such space and (this is extremely important) being able to contribute to the person’s own food supply is of immense value. To be able to contribute to one’s own needs and raising food are two of the most powerful driving (innate) forces in most humans. PFAS LLC has designed our installations to accommodate most standard wheelchairs and have made the table legs on the grow trays adjustable to best fit those so confined. The width of the grow trays is also a consideration and can easily be adjusted in the building phase. When a client requests an installation be made for those with ambulatory disabilities, very little modification is required from the standard model to accomplish this change. Those in retirement centers, veterans centers, rehabilitation facilities, long-term care centers can all benefit from a Portable Farms® Aquaponics Systems installation on their premises. The installation can be ‘free standing’ or used as an addition to an existing structure. The flexibility in positioning the building is another advantage of the Portable Farms® installations.

AFTER: 40 Days After Planting

For those who have difficulty reaching the ground to perform repetitive tasks, having a grow tray at waist height that can be reached across, from both sides to the middle, with the opportunity to grow the plants of their choice all adds to the joy of planting, growing and harvesting the best tasting produce they have had in decades. Aquaponics is the gift that keeps on giving. The interior space of a Portable Farm itself is soothing, quiet, comforting and very easy to keep clean. The standard maintenance routines require minimal time and easily carried out either under a standard services contract or by a trained staff member.  The added benefit is the locally grown produce is raised with minimal care and can be consumed by the facility. Everyone in the facility will benefit. Even a backyard installation adds immeasurably to a person’s life and well being. With the increasing cost of food and the growing concern about the climate change, one of the answers is aquaponics and now even those with ambulatory disabilities can contribute to removing some of the pressure and lowering the carbon footprint of their existence.

Basil is a High-Value Crop for Aquaponics

Basil – A High-Value Crop for Aquaponics
by Colle and Phyllis Davis

Basil is a high-value crop for aquaponics. It is enjoyed as a fresh-leaf herb on meats and vegetables, prepared in sauces such as pesto, or dried and used in many recipes in cultures throughout the world. Basil grows well in aquaponics systems because of the ideal growing conditions created with warm water and ample sunlight.

When basil is grown in traditional in-ground growing, it is a ‘summer crop,’ but when grown year round in aquaponics systems, it is considered a ‘high value crop,’ especially when sold locally in cold climates when basil would normally be normally be considered ‘out of season.’

  • The normal pH of the water in Portable Farms® Aquaponics Systems ranges from 6.5 to 7.2 for ideal growing.
  • Basil enjoys a very wide pH range between 5.1 (strongly acidic) and 8.5 (alkaline) with a preferred range of 5.5 (strongly acidic) to 6.5 (mildly acidic).
  • The roots of herbs enjoy being well-drained between watering cycles.
  • Portable Farms® Aquaponics Systems allow for full sun or the option of grow lights so herbs and vegetables can be grown year round which is ‘out of season’ in many areas and owners may collect top dollar for crops from local customers.
  • Basil seeds grow well in rockwool or Oasis Horticubes.
  • Basil plants may be placed on 8 inch centers and planted off-set in each row within a grow tray allowing for ample room for lush growth for each plant.
  • The root systems for basil do not spread out and are not complex root systems which makes for consistent and easy water flow throughout the grow bed during watering cycles.
  • The basil plant usually grows to a height of 18 to 24 inches and produces many offshoots for harvest per plant.

You can cut back basil two-thirds of the entire basil plant twice before replanting the basil to begin the process again. This extends the harvest of the basil leaves and provides more cash-value crops instead of a one-time ‘grow and harvest cycle’ like lettuce. Basil can also be raised in batches and sold to customers as entire plants.

  • Since one plant will produce for four months (after a two-month initial growth), you would only replant new basil plants every six months and be continually harvesting during each four-month harvest cycle.
  • Each 40′ tray will grow 450 basil plants (on 8″ centers) which allows for 900 basil plants per year grown in a single tray. These 900 plants allow two cuttings each which can be sold to local consumers at wholesale or retail prices in your area.

Bonus – Pesto Recipe We Use When We Harvest our own Fresh Basil

We cannot count times the many times we’ve invited friends to sit with us to enjoy an entire meal of fresh pesto sauce made from our own basil that was spread thick on hot homemade whole-wheat bread and served with sliced, freshly-harvested tomatoes from our own vines in our Portable Farms® Aquaponics Systems. It’s a real pleasure to share healthy and simple food with friends. This is our definition of ‘the good life.’

Portable Farms® Pesto Sauce – Fresh off the Vine

This recipe makes about 2 cups. If you plan to freeze the excess pesto, avoid adding the crushed garlic to the recipe and wait to add it until you thaw and serve the pesto because the garlic can taste bitter after freezing.

Ingredients List:

  • 8 cups fresh basil leaves, torn off vine (discard the stem/vine)
  • 1 cup freshly grated Parmesan cheese from a deli or fine store (don’t use the powdered Parmesan you shake out a canister for pasta)
  • 3 cups of pine nuts – slightly oiled and then toasted brown in an oven for 20 or 25 minutes
  • 3 garlic cloves, crushed
  • ¾ to 1 cup extra-virgin olive oil (depending on how thick you like your pesto sauce). If you plan to freeze your pesto for later use, do NOT add olive oil until you defrost.
  • 1 teaspoon sea salt
  • ½ teaspoon fresh black pepper


  • Place basil, ½ of oil, cheese, pine nuts, and garlic in a food processor. Pulse several times, until well chopped.
  • With machine running, quickly add olive oil in a steady stream, allowing pesto to mix blend and become cohesive but don’t over blend. Process until desired consistency is reached, season with salt and pepper, and serve. Again, if you plan to freeze your pesto for later use, do NOT add olive oil until you defrost.

Start a Hobby Farm for Family Fun 

Start a Hobby Farm for Family Fun
– by Colle and Phyllis Davis

Start your own hobby farm and invite your entire family to care for the fish and plants to grow your own food. A small farm requires only five-minutes a day to feed the fish and tend to the plants.

For most people, having a built-in cushion of almost anything provides a really great feeling of comfort. The topic of ‘food security’ for families is in the news today especially in cold climates where fresh food must be imported up to eight months per year instead of being grown locally. Aquaponics offers the choice for growing fresh food grown near your kitchen and available year round.

To have a few months of money that you’ve saved safely tucked away, or a full tank of gas, or cupboards stocked and supplies in the house makes us all feel much more secure. Now, add to that a nice garden, some survival foods tucked away and the means to obtain more food on short notice and you begin to feel that you and your family are ready for whatever might happen in the future. And something will happen, let’s all hope it is something nice.

Assuming you have some of the items (listed above) taken care of and you can afford to create a real survival farm/garden, consider an aquaponics system inside a weatherized greenhouse, basement, garage or even an outbuilding. To size it properly, use the formula for a highly efficient aquaponics system (think Portable Farms® Aquaponics Systems) of 25 sq ft of grow space which is necessary for each adult. This ‘small acreage’ will feed that adult all of their surface vegetables year round forever and provide a source of protein: fish. You may want to increase the total area slightly to insure you can feed those who show up at your door if times do become more difficult.

Ah yes, the cost. To build a greenhouse (10 x 30′) to house a single PFAS Module for feeding four adults will cost somewhere between US$3,500 and US$5,000 depending on many factors. Cost of greenhouse, climate considerations, floor covering, local lumber costs, etc.

There you have it. If you put the PFAS in your basement or garage there is no cost for the greenhouse, only the PFAS Module materials and some grow lights for indoor growing. Neat, elegant, practical and affordable and the best part, it’s AVAILABLE TODAY.
