One of the most frequently asked questions we receive is, “Can I grow marijuana in my Portable Farm?”
There are many variables to this question but, “Yes, you can grow marijuana in aquaponics.”
In this series, we discuss the different ways to grow medical herbs in aquaponics, the necessary modifications to produce the best results, and the pitfalls of single cropping and mixing herbs with other plants in the grow table.
- In our first year of offering the Portable Farms Aquaponics Systems training in 2008, the most common general question we received was, “How does that thing work?” meaning aquaponics.
- The next question was, “Can I grow marijuana in aquaponics?”
Step back for a moment. When we launched Portable Farms in 2008, the herb was illegal in most places in the US, including California, where we lived. Supporting an illegal activity with the use of our technology gave us pause and our lawyers warned us against pursuing anything related to marijuana. We would not be doing anything illegal by selling our systems for the purpose of growing marijuana by our customers, but we were advised to avoid anything that could draw negative attention to our young and thriving company. We took their advice.
About that time, a competitor of ours in the aquaponics business decided to grow marijuana and they both went to jail. We wanted to avoid any implications or suspicions that could create legal problems.
Now, 12 years later, the laws have changed in about 19 states that allows their citizens to grow small amounts (generally 6 to 12 plants) of marijuana for personal use. Disclaimer: Check with the laws in your state for laws related to growing marijuana. *Disclaimer, we accept no responsibility regarding legal advice or updated rulings regarding growing marijuana plants for personal or medicinal use.
- A list and links posted below (our thanks to productiongrowers.com for their thorough reporting of all-things-related to marijuana) regarding states where growing marijuana is legal and states where it is prohibited).
- As you have may have guessed by now, marijuana and the growing of marijuana along with offering advice has been a legal-slippery slope for us. Our company, PFAS LLC, is moving from only giving a few general suggestions on the phone to customers who inquire about growing marijuana to today — we have now begun writing and publishing growing advice for the maximum production of marijuana and other herbs in aquaponics. Our reluctance has once again been prompted by moving our residence and corporate headquarters to Virginia, a state that does not currently allow the use of marijuana or the growing of marijuana for recreational or medicinal purposes. We are law abiding citizens, but also aware of the demand for information regarding the link between aquaponics and marijuana. We do NOT grow marijuana. FULL STOP.
Information for Growing Herbs in Aquaponics
One module of a Portable Farms Aquaponics System
Growing herbs requires research for each plant to determine their watering needs. Many herbs require less water than the vegetables or greens that are grown in Portable Farms. In fact, many plants prefer loose sandy soil over aquaponics growing for that very reason.
All Portable Farms® Kits are commercial kits designed to support Grow Tables up to and larger than 200 sq ft (18m2) and work even for the smallest Grow Table installations. The difference is the timing of the water flow.
Aquaponics is best known for growing greens. Image above is a tray of Romaine Lettuce.
If you want to grow a few ‘herbs’ in your regular Portable Farms® Module, plant a few and see how they mature. You may find they require less water than two water cycles per day.
Changing the timing on the water pump to once a day with a longer cycle still gives you great vegetables, and your herbs will be happier. If you are only growing greens, changing to once a day timing will slow their growth a bit because they love water. Herbs, not so much.
Mixing plants in a single Grow Table means compromising on production because of the different moisture needs. Tomatoes, cucumbers, beans, and peppers dislike wet roots. They need plenty of water in the morning, but not in the afternoon.
For example, lettuce, Swiss chard, bok choy, kale, mustard greens, and collards enjoys two water cycles a day. This water need is why raft culture works well for them; their roots are in water all the time. Herbs prefer a much dryer root zone and become waterlogged and unhappy when over watered.
Next, in this series on growing marijuana in Portable Farms Aquaponics Systems, we will cover modification to the basic Module layout to produce a more abundant crop. You can still use some of the Grow Table for regular vegetables, so you can grow your herbs and vegetables at the same time.
