Basement is probably the best, though controlling odor is going to be hard if you don't have the area sealed off some how. And you'll still need at least some sort of oscillating fan directed towards the plants.

Either way in any area heat and humidity will big your biggest enemies.
Orzy Reviewed by Orzy on . is it bad to have a "open" grow indoors? What I mean by open, is just that open. No boxes, no fans, mold wrap. Is basements ok, when i say basement, i mean temp controlled with no windows, or is a attic better? I also have a rear room that is screened for 3 seasons and it always about 70-90 % and about 60-80 humd.. .. I am going to be growing 3 fem Cheese plants.. I know they GET STINKY AS FU@k, but just curious.... Rating: 5
