Right now we are having record high temps here for this time of year. It will definately get much colder. Above closet is the attic, along one will is the hall, the other side is a plumbing space between the closet and outside. I will not heat the room where the closet is located. I can keep the closet door cracked for quite a while yet before odor will get to be a problem. Also the lights will be much higher above the floor by the time it becomes necessary to close the door. The space is especially hot now because the lights are only about 12 inches over the floor. Lots of heat and light in a small space. I am thinking that once it becomes necessary to close the closet door the heat will not be a problem but I will have to put a dehumidifier in. I can swing the door once or twice at night and then blow the sweet air outside to keep the air fresh in the grow area.
Most of my seeds have germinated and I have placed them in the pots. Should be poking their heads up by tomorrow.
Best Wishes
