The GT205 is a self-contained NFT system that is ideal for small spaces. Their compact design makes the best use of your grow room. The original Gro Tank was the first hydroponic system designed for the hobby grower and has been around since 1979. kit contents: Tank, top plate, corriboard, spreader mat, PH down, PH test kit, pump & emptying tube. Tank volume: 20ltr Dimensions: 695mm x 385mm x 185mm All Gro Tanks are compatible with an Auto Top-Up System, a perfect way to expand the capacity of your NFT system. Connected to a header tank of any size the Auto Top-Up maintains the level of a nutrient in the system reservoir taking the work out of growing and allowing you to leave your plants for a longer period.   NFT Benefits:  A ‘Bare rooted’ technique means unrestricted access to oxygen. Greater uptake of water and nutrients. Never under or over-fed and no nutrient build-up. Up to 4x greater yield than conventional growing methods. Plants are never under-fed or over-watered and there is no build-up of salts in the root zone. Gro-Tanks is just 20cm tall Reduce manual watering frequency – connect an Auto Top-Up system to the NFT system and plants can be left unattended for longer periods. Less chance of disease, less waste material to dispose of. NFT Growingtips: Golden Rule – Ensure plants are root bound before they go into the system. An abundance of white roots should be visible on the outside of the starter media. As a rule of thumb: 1 plant per square foot. This can be increased or decreased depending on plant variety. The pump runs for 24hrs. No need for a segmental timer or feeding schedule. Completely remove plastic wrapping from Rockwool cubes or remove pots if using soil or coco. This allows the roots to access more oxygen. NFT is a bare-rooted growing technique. All but the smallest of plants will need additional support, i.e. yoyos or pea netting. Cut lengths of spreader mat long enough to allow an overhang of a few inches from the channel into the tank. No trickling water sounds!
