actually if you read the title of the thread you'll see the question pertained to sog, but thank you all for your replies, and to stinky with the root info.
males wont be a problem in the flowering chamber because i'm in the process of building a cfl lighted mother/cloning chamber. with this i will be able to put say, 6 small rooted clones in the flowering chamber, 2-4 weeks later i would put 6 more in creating an alternating perpetual harvest with fresh clones being rooted in the clone chamber.
what i' m mainly concerned with is the size of the plant sites/ netpots or what have you in the top of my dwc. i was thinking of using hydroton in yogurt cups with slits cut in them like a net pot so i could use them to block out light if a site doesnt have a clone in it. would this 2-3 inch cup hold a nice cola ok?
also regarding maintenance of the dwc, i was thinking of using a small submersible pump in the res. to remove old nutrient solution.
