Aquaponics cannabis systems

Let’s talk about aquaponic cannabis, a breakthrough method of organic cannabis farming. This up and coming technology can produce great tasting marijuana without taxing and wasting resources. It is somewhat similar to hydroponic weed growing, as it uses mostly water in place of soil.

Aquaponics is a self-sustaining system for growing fish and hydroponics. The waste from the fishfeeds the marijuana plants, and in combination,the root zone is the biological filter that is used to clean the water for the fish. The aquaponics system of growing can be utilized for indoor or outdoor growing. This method of agricultural farming was refined by a couple of farmers in Missouri which then became the model for commercial agricultural aquaponics. Aquaponic greenhouse systems have changed the way that organic farming is done. This method was designed for a higher yield of marijuana, not for a higher yield of fish.

If you wish to try this method of growing weed yourself, there are a few things to take into consideration. If you were already thinking of starting to grow cannabis plants, why not setup an aquaponics fish tank? You can easily use an old fish tank to get some experience growing cannabis. After all, you can now legally grow up to 4 plants since the legalization of marijuana in Canada. The robust common fish, Tilapia seems to be the fish of choice when implementing this method of growing cannabis, however, obtaining this murky water fish may be difficult. If you do not want the fish as a food source, ornamental goldfish can substitute quite well. These fish can be easily sourced from your local pet store.

Just outside of Hamilton, Ontario sits the world’s only licensed producer of medical marijuana that uses fish in their production. Green Relief Inc. is the operator this aquaponic farm. This pesticide free process of growing their medical marijuana has taken two and a half years to develop. The current operation is underground. All that is visible to the passerby are the ventilation equipment that is sticking out of the ground. The plant is situated in prime farm landand is built into a hill. The use of filtered fish waste as a fertilizer which in-turn provides clean water for the fish is a cutting-edge industry.

The closed-loop system that Green Relief Inc.utilizes uses farms of tilapia fish. The 6,000 fish and 4,500 cannabis plants use less water than conventional farming. This method seems to deliver a 10%-20% better yield at the same time as the 90% reduction in water use.

The company purges the 16 fish tanks that they support every five weeks. The tilapia fish from these tanks are donated to a homeless shelter.

The company also has plans for a 100,000 square foot complex in mind for the near future to be built in Horizon, Hamilton that is expected to produce 15,000 kilograms of aquaponics cannabis annually.

At present, there seems to be no other method of cultivating higher yields of natural organic bud than the closed loop aquaponics method.

Going forward this type of marijuana farming may become more common place among all marijuana farms across Canada.
