Precision Growing in Aquaponics Systems

Precision Growing with Portable Farms® Aquaponics Systems
– by Colle and Phyllis Davis

Precision growing is defined as ‘delivering the exact nutrients and other requirements necessary for growing  healthy plants with the required amounts of food, nutrients and light.’

Aquaponics uses grow tables in a much more efficient and effective manner. The water’s pH and carefully timed delivery system as well as the addition of macro-nutrients and micro-nutrients are all very important to successful growing results. So are the available light level and intensity and the temperature and the air flow in the building. Delivering each requirement at all times results in maximum yields in record growing times. The added expenses of these high tech growing systems are very quickly offset by the dramatic increases in yields.

  • Controlled environment agricultural growing is very quickly becoming the state-of-the-art production because of the multitude of advantages. These include:
      • Extended growing season – often year round
      • Greatly reduced consumption of water even with in-ground growing methods
      • Less expensive and more accurate pest control – often pests are eliminated as a problem
      • Growing is placed much nearer to markets in many cases
      • Less chance for crop losses due to weather, pests, water loss and theft
      • More efficient use of fertilizers and nutrients used for maximum production
      • Custom and high-value crops easier to grow for local markets.

Portable Farms® Aquaponics Systems actually deliver a slight excess of everything the plants need, even the light, so every plant always have the perfect conditions for maximum growth. PFAS also has other advantages:

      • Less water use than any other type of commercial growing system available today
      • No pesticides are ever used
      • The waste water is a valuable fertilizer that can be used on other crops or sold at a profit
      • Waist high work area
      • No single point of failure
      • No weeding – ever
      • Watering is automatic
      • No soil or dirt inside the building.

For maximum production/yield, PFAS LLC recommends the following ENHANCEMENTS to a regular PFAS installation:

      • The addition of micro-nutrients that include  iron, magnesium, calcium and potassium and 53 other vital minerals are supplied with organic FF-Mineral Rock Dust
      • High performance greenhouse coverings that protect from weather extremes.
      • Insulation of all walls and roof that do not contribute direct sunlight to the grow trays
      • Grow lights capable of providing maximum full spectrum lighting for both greens and blooming plants.
      • Inert growing medium for planting seeds
      • Trellis installation for maximum vertical growing for blooming plants (tomatoes, cucumbers, beans, peppers, etc.)
      • Full monitoring system of all functions within the building that notify operator of any necessary adjustments required
      • Low cost fish tank heaters
      • Automatic water leveling system for fish tanks.

These controlled-environments-precision-growing-systems are capital intensive on the front end, but they produce income very quickly and continue to produce income over long periods of time with only operational expenses needing to be covered. The ROI on the Portable Farms® Aquaponics Systems is only three to five years. Investors really appreciate these advantages and the new ‘farmers’ appreciate the opportunity to reap huge rewards for their efforts.

    I have been planing on a small business for a while. I intend to start with a 30 x 60 x 8 foot wall greenhouse all automated .The product that I have found to be needed in this area is cabbage, iceberg lettuce, cucumber, and tomato. Can you tell me how many units I can install to maximize the space I have? I also am planning to install a 40 ft x 8 ft x 8 ft reefer cooler and a 16 x 20 prep area with a loading dock. The land greenhouse and other structure will cost around 120,000 dollars, what will be the estimated ROI ? I will also have a college age major helping me do the work. Also have plans to expand.
    I really enjoyed all the articles on this subject that you have put together.

    1. Kevin,

      Thank you for your inquiry.

      The building size needs to be adjusted because the suggested footprint is very hard to work with to lay out Modules efficiently. The Modules are generally 7.5 x 44 or 8.5′ x 36. Using the shorter/wider Module size a building of 30 x 72 will hold 8 Modules nicely.

      You are spending money on a reefer that you will not need. Your produce will leave for local buyers the day it is harvested.

      Who is your market? What do they want to buy? Cabbage is a field crop and it is not generally economically feasible to compete with the regular wholesale market. You need to make sure you have your market survey completed before you spend any money on the building of your installation.

      An installation of this size only requires one person to operate. The second person would be a part timer at best.

      The Aquaponics University Portable Farms Aquaponics Systems Course© and the Commercial Aquaponics GOLD ebook are your next steps.

      We trust this information helpful in moving your project forward.
