So I could easily put them outside hidden but not smelt? thus Keeping my girls safe except for what I want to pollenate?
I'd say for sure. A tip i got from @Nan is a great one in your situation. Grow out the males in the grow room until their Balls are fairly well formed. Then cut the main stalk/branch off the male and place in a window in a vase of water on a glass plate. The plant will continue to mature and drop pollen on the plate.
