Hydroponic NFT Setup

Anyone here have this "gutter" style of NFT setup running? I'm using 4" PVC, and have seen plenty of people with vinyl gutters instead.

Nice. You are ready to go man.

i did a lot of research before starting this and still couldn't find too many people actually growing in a setup like this. i'm curious as to if anyone has seen this before and could point me in the right direction for some journals or the like.
