NFT Microtube is used to deliver the nutrient solution into the NFT gullies.
The tube has a 4mm Internal Diameter and a 6mm Outside Diameter.
This flexible tubing is usally cut to 300mm or 400mm lengths. Two tubes are used per gully to effectively spread the thin film of nutrient solution across the base of the gully and to ensure that one tube will always be working if the other one ever becomes blocked.
One end of the microtube is installed into an 8mm NFT Top Hat grommet to hold it in place in the top of the NFT gully and the other end is placed into an 8mm Top Hat grommet in the NFT feedpipe manifold to provide a sealed delivery point.
