My current setup is two 600W HPS lamps in a 4'x8'x6' grow tent. I am moving it from a garage, to a custom backyard shed soon. The room is going to be 8'x12'x7'. Unfortunately I don't live on the property, so I'm trying to make everything as automated as possible. I just bought [ame="http://www.amazon.com/Custom-Automated-Products-CAP-XGC-1e/dp/B003H7KTN6"]this controller[/ame], and I was wondering how powerful of a cooler, heater, and dehumidifier I need for a 8'x12'x7' room in SoCal. Would a 10,000 BTU cooler be overkill or not enough? Any help would be appreciated Also, might be a stupid question, but could I use a heater/cooler/dehumidifier combo?
