OK thanks turtle but I still need to know what the best system for me would be. The thing with the control bucket with the DWC systems happens from something like the plant not absorbing the nutrients then the bucket gets filled with too much or something about the toxins gathering. I like the DWC systems because if I use like a 3 gal bucket for each plant I can just replace the water on each of them one by one. Now that I think about it, I'd much rather do a DWC in a big rubbermaid tub, but I don't know how to drain the bucket (would be a little heavy plus the fact that moving a lot of fully grown plants wouldn't be such a good idea.) then refill it quickly (it would be hard to have like 20 milk jugs of ph adjusted water to be just sitting there.)

Any help would be greatly appreciated (wow i say that a lot). Thanks in advance (that too)
