Can-Fan Backdraft Dampers

Unlike the competition, Can Filters are pelletized to maximum the cleaning of the growing environment and air flow for reduced temperatures. Most other brands use a powdery form of carbom which just floats through-out the grow room covering your equipment which creates soot as well as clogged plant stomata. Thereby, reducing plant transpiration, 

not to mention diminishing viable lumen concentration to your plants. Can Fans speak for themselves. They simply blow the competion away. Garden State Hydroponics has always and will always only recomend Can Fans and Filters. Try one for yourself and see the difference quality and performance makes
