I never realized how many Anti-DWC people there were... if the last few posts are any indication... a whole barrel of monkeys has come away from DWC with a bad taste in their mouth.
I'll deffinitely hold off for now and just change up the system Via a different media and much more frequent fill/drain cycles. As long as some significant change is taking place - I'm happy to keep experimenting in hopes of a better return.
I just want to hit 1lb per 1k lamp... (7 lbs. per harvest would tickle my fancy quite well enough). If ebb 'n flow can still let me get there, so be it. Still contemplating co2, but the kicker there is that this is a non-A.C. grow just using straight ventilation like in a greenhouse. I guess you can toggle the co2 and the exhaust via a timer or controls and such... but i've pulled a 1lb per 1k w/o co2, damn't, so hopefully i can get there again w/o having to introduce co2 !!
