i agree with full of purple, but personally id forget about the 1000 (unless u have a/c available just for the heat) n stick with the 600hps for flower and 400mh for mothers n clones.. 6" inline fan(400-450cfm) it'll probably be kinda noisy so id also get a speed controller to help with the noise! id give potential mothers a month at least(soil) or just a cpl weeks(hydro) to see if one grows more vigorously or has better traits then the other..i dont think you NEED an intake fan if ur tent has the passive intake vents, which most if not all do have.. BUT im sure a 6" duct booster fan would suffice if u WANT active intake(my preference).. JMO
