BUYERS GUIDE

NFT Hydroponics Buyers Guide

Nutrient Film Technique (NFT) is a very popular method of hydroponic growing that is used widely in both residential and commercial hydroponics. Allot of the salad crops you buy from the big UK supermarkets have been grown in NFT - in allot of countries it is actually very difficult to buy salad crops that have been grown in soil.

How does NFT work?

NFT is brilliantly simple - the roots sit in a thin film of oxygen rich water that flows via gravity on an approx 1:40 slope - for every 40cm centimetres of flow the channel drops by one centimetre. This keeps the flow at a level that the roots find comfortable and are able to take what they need from the solution.

NFT is what's known as a "recirculating hydroponic" system, the water is pumped up to the top of the channel and turned into the film that flows back down over the roots before being collected in the tank and pumped back up to the top all over again. This closed type of system saves water, and as long has the tank capacity is enough for the type and requirements of the plant, means that a once daily check and top up of the solution is normally enough to keep everything in balance.

Which NFT System should I buy?

We stock several different sizes of NFT systems - they all come from the same UK manufacturer and are tried and tested for domestic use of two decades. The GT205, GT424, GT604 and GT100 are meant for smaller growing spaces and grow tents, the Multiduct 2 & 3 channel kits are for larger growing areas and require a bit more work to set up and operate.
