Stan, Thanks for all the great advice and tips. I can see your point about the NFT flow technique – although water height can be adjusted, it would rely on roots being the same length. That’s unlikely for different varieties of plants. How did you configure the sprayers in the 5X5 fence post? A single PVC line down the center with sprayers between net cups? I’ve attached a preliminary rail layout plan and if I went with sprayers, it looks like it would take about 27 sprayers. I’m not sure the
pump I have could run that many (or I could upgrade to a bigger pump). Also, I may be way to “aggressive” in the number of net cups. Any recommendations on net cups per 4’ section? This is still in the planning stage, no 5X5 fence rails (and caps) purchased as yet, but I have enough sprayers and PVC. Your thoughts / advice?
