What does it take to breed truly fine cannabis? It requires an acute sense of the universe and unwavering attention to detail. Of all the people I've met who consider themselves breeders of cannabis, none embrace the spirit of organics quite like Breeder Steve. Never one to follow the traditional path, Steve began experimenting with a technique he calls "guppy-ponics" to feed all his plants. Essentially bioponics (biological hydroponics), the name reflects the fact that all the nutrients Steve's plants need come from the water in fish tanks that have been stocked with guppies and other fish.
As fishes live, they eat, then poop. Over a short period of time, fish waste converts itself into all the essential nutrients plants need. Steve drains the water from his tanks to water the plants. Then he tops off the fish tanks and the process starts again. The plants themselves are not grown in one particular style. Steve has used this method to feed plants on ebb-and-flow tables and pots filled with grow rocks. He does prefer, as I do, large buckets filled with a high-grade soilless medium. After feeding a 4,000-watt room exclusively off a 90-gallon tank for over two years, Steve learned exactly how to make this system swim.
