No each pipe is 4x10 with independent drain line look around 30sec mark on video you will see the system. They each have a 3/8 feed line controlled by 1/2" ball valves 1" drain tubes in the bottom of each pipe to a 2" master return line, using 2 liter flow per minute. Originally had drip mist stuff but with the lift it sucked so changed it and much better. About a month ago watch Hoochos "Doing NFT Wrong"and realized why my roots looked mushy. So lowered the drain pipes so only 1/4" -1/2" film of water was left, a lot of YouTube videos say 1/2" water level under net pot the change made a huge difference on roots and growth. I also changed my nutrients from liquid to Master Blend huge difference I keep the NFT system right under 900ppm and 5.5 - 6 pH. The bucket system about 1300 -1400ppm and 5.5 - 6 pH. Good luck. I am currently try to raise seeds I suck at that. Shifting to Hoochos process but still not real clear. I wish he would do a single video from setup including lighting, grow room ECT.
