Growing marijuana is rather a contentious subject these days. However, if you’ve consulted with your lawyer/consultants and you know for a fact that it’s absolutely legal in your state or have legal permission, then you may want to know how to grow marijuana in an aquaponic system. If you don’t maybe learning how to print t-shirts will be better. (We are not liable for any illegal use of this information).
Here are some tips that you should keep in mind:
- You need a lot of patience. An aquaponics system is a constant juggling act involving fish, bacteria that converts the fish waste into useful nutrients, and plants. So you’ll need time to at least colonize the bacteria, and then more time afterwards to get the balance right.
It takes a while to get that proper balance. This may involve changing the water, adding or removing fish, managing pH, and adding nutrients.
- Take note of the high nutrient needs of the marijuana. Building your bacteria biofilter can take at least 6 months, so in the first few months your marijuana may not get the nutrients it needs from the fish waste. This means that during the first few months of your system you’ll need to supplement the nutrients.
Also, during the flowering-budding stage, the cannabis plants can really consume a lot of nutrients. So you will need to account for this. It helps if you already have experience with tomatoes for aquaponics, as they both have similar nutrient needs. They’re very different from the simpler needs of herbs and lettuce (which are best for beginners). (more…)
