Dr. Howard Resh"s PVC Pipe NFT Recipe

This web page has a wealth of information, but I was particularly interested in this part of the article.

PVC Pipe NFT: An alternative to using the commercial NFT gutters is to make your own system from 2-inch (5-cm) diameter PVC pipe. Cut round holes of the correct size to fit the growing cubes you are using spaced at 7 inches (18 cm) along the pipe. Be careful when drilling the holes that they align in the same position that will be the top of the gutter. The remainder of the system is set up as described for the other NFT channels using benching and an irrigation system. An inlet header and catchment pipe circulates the solution to and from the gutters to return it to the cistern. These systems will grow uniform, high-quality lettuce.
