You will probably need to move the tubs around, so they get even light. I like your idea for dividing the res. You want to be able to remove plants if needed i.e. plant problems, infestatins or whatever. just my two cents... Good luck!!
yeah...well i got this buddy of mine who can sell me blueberry kush clones for 30 each... atleast there 100% female and saves time.. i can imagine breeding big bud with blueberry kush. what you think that will turn out like?
