Ok, this time of year I am just fine growing. I put an inline fan on my AC line going into grow room where the tent is. An keep temps 60-68 in the room and 68-75 in the tent. That’s fine and dandy when it’s hot out and the central AC is running. This fall when the heat kicks on is when i’ll have issues. Looking for a stand alone AC unit that goes to that room. Cannot put a condenser outside. The room is 4x7x8 that I want to make a sealed off grow room in the future. I do vent outside with my exhaust from the grow room. I have thought about mini split units but the condenser would have to go in the attic. Not sure if that is doable. I don’t want to drill more holes into the outdoor walls than needed and these portable AC units don’t seem dependable enough. I have my attic available for any AC unit needs. Do I have any options?
