I've been growing using 4" PVC pipe, water sprays in on one side and drains out the other with about 2" of water in the pipe. I had four pipes side by side 8' long with 3 HPS on a light rail and Co2 with great success. Now I supper sized it....I have 4 pipes side by side 19' long with 6 lights and Co2, and now I get a good harvest but not a great one like I did before. I have been reading about DO and I'm thinking maybe the pipes are so long that I don't get good O2 to the roots, if so how do I improve the O2. I use the continual harvest method and I noticed on the new setup there is brown crap in the pipes....must be from the roots. any one have any in put.
Thanks
