Grow Tank NFT GT604.
The original and still used by thousands, GT604 uses the NFT (Nutrient Flow Technique) system of growing! Plants are sat on a spreader matt lined tray and placed on top of water tank, roots grow into the matt. Nutrient rich water is pumped from the tank onto the tray flowing over the roots, excess water then flows back into the tank at the opposite end of the tray. The plant medium simply soaks up whatever it needs form the flowing water, this process also circulates and helps oxidize the nutrient. Very reliable and easy to use. Kit contains tank, tray, top plate, pump, spreader matt, accessories and fittings. Use with an Aerator and Heater to increase oxygen supply and keep nutrients at the right temperature, all sold separately.
