I am doing an indoor setup that is about 9ft x 11ft x 8ft so far cooling hasn't been a problem cause we used the central AC last summer and this winter has been cold enough so I don't need it yet but I will want an Air Conditioning unit in by the time it gets hot because the central unit is overkill and far too expensive. Any recommendations on in room units so i don't have to do any obvious installation in the window and such or are those gonna be my best option? Also when is the most effective time to use Co2?
