I'm looking for anywhere between .5-2 pounds per harvest whatever's practical though, I was planning on making chambers/boxes and possibly considering doing perpetual harvest.

A flowering chamber and a vegetation/clone chamber. I was thinking of doing HID for flowering, maybe doing sea of green or screen of green (maybe 600 watt) and flourescent (I was considering trying compact flourescent but if that doesn't work I can always just use tubes on a chain method).

Do you think it would be worth it to get a hole in the roof to get some fresh intake air or does that not matter too much?
