Hi guys I have a 30 ft by 30 ft garage that's detached and insulated, but no heat or air conditioning. What I was wondering is if I build a 10x 10 room and use a ac window unit to cool it in summer and heater inside to heat it. I'm going to vent hot air into rest of garage. I'm going to use the proper systems for air, odor, and air exchange. But I'm not sure how to set this up using the same area for vegetation and flowering. I also want to keep this low key and under the radar. It's for personal use only. I really need some expert advice cause i am sick of buying my medication!!!
