Marijuana fertilized by Fish Poop? A Canadian Cannabis Producer is making it Happen
Global News reported that Canadian cannabis producer Green Relief Inc is using fish to grow their marijuana plants. The aquaponics system combines aquaculture and hydroponics, raising tilapia fish in tanks where the cannabis plant’s roots dangle in the water. Microbes then convert ammonia from the fish excrement into nutrients for the plants, which in turn filter the water, creating a sustainable closed-loop system.
Aquaponics is a production technique that takes the benefits of hydroponics but adds fish into the mix. In normal hydroponics, instead of using soil as the plant’s main source of nutrients, the plant’s roots lay in nutrient-rich water, which gives producers a more accurate control of the plants’ overall growing environment.
In Aquaponics, an ecosystem is created, in which the fish’s waste is used to fertilize the plants, which in turn purify the water for the fish. It’s a type symbiotic environment that mimics nature’s process, and it can be used to produce any kind of fruit or vegetable, without the need for artificial fertilizers.
It may seem strange at first glance, but co-founder Warren Bravo calls it “the agriculture of the future.” And he has good reason for saying so. It’s well-known that marijuana grows require a lot of H2O – some estimates say it takes around one gallon of water for each pound of processed bud produced. The aquaponics used by Green Relief use 90 percent less water than traditional grows, and yield 10 to 20 percent more bud.
Green Relief owns the rights to Cannabis Aquaponics all across North America and is planning on staying out of the recreational market, for the time being, focusing solely on the production of high-quality bud for the medical communities.
