Thanks for the follow on my NFT project, if you do plan on building one I recommend making the input manifold out of a smaller diameter pipe so there is better water pressure for circulating the water into each of the rows.

I appreciate the additional info. I really liked your idea so the one I am designing is more of a kitchen top controlled environment. I was going to use DWC but went back to NFT when I was thinking about cleaning out the nutrient bath. I use a smaller container but replace once a week. I just wish I had a background in plumbing. My quest is all about growing THE BEST herbs and leafy greens...we shall see.
