Ikon produce an NFT system with a smooth base and a slight concave shape to insure the nutrient solution runs down the centre of the channel. Snap on/off lids make for easy root inspection and cleaning, integral plant support and low channel level make these systems very easy to use. Plastic parts are guaranteed for 20 years! The system comes with channels, nutrient tank, pump all fittings and support netting. This system of NFT is highly recommended and consistently brings in top results.
