The green house is getting close to completion and we have the parts for an NFT system ready to go. This system is build with 6 inch PVC. The question we have is propagation since roots will not reach the nutrient obviously from the start. The thought I hade was using a small raft system to propagate in since the starts will not need a lot of space. Is this a good idea or is there another way to start NFT plants that I have not found?
