yeah, i'm slowly coming to the realization I may have to go back to soil.. boo. I think I could do the dwc bubbler with using a smaller tub inside the bigger one. With 4 plants From what I remember I think i could do a scrog with few problems but the lst would be very tuff. I was thinking of maybe upping it from the 22 with a 15 gal to something a little bigger with the 15 gal in it to give the babies a little more room. Thanks for the thoughts. Once i get started i'll post some pics to keep everyone updated.
