At this point I no longer plan on growing root vegetables with this NFT system and instead plan on focusing on leafy vegetables, possibly small flowering vegetables, and perhaps scallions, radishes, or shallots. Will deep water culture work better for things like potatoes and beets? I understand that standing water will cause root rot, especially with large root masses, so will having a short run system that uses several short tubes instead of a couple longer ones help prevent water buildup? I'd also be interesting in your idea on quickly germinating and moving green onions, if you are comfortable sharing it.
Your corn setup sounds very interesting as well, would you just be starting seedlings in rock wool?
