We used to run aeroflo systems from GH with the square pvc fence tubes. Once the plants get big enough its aeroponic/NFT with the thin film on the bottom of the tubes. We looked into adding a fogger to fill up the rest of the tube with solution without permanently submerging the roots. I got the best BM yeilds i ever had from this system. 2x1000 lights in vertizontal reflectors gave up over 5#
When we got medical we went for 1#plants and never looked back
