mscaboo Reviewed by mscaboo on . Co2 idea! Easy, cheap! No setup required! And is as small as a drinking botle! Yo :) I had the best idea ever how to get Co2 in the grow room! I thought of it yesterday while i was making my tap water fizzy with a high pressured Co2 bottle which fires Co2 into a compressed glass of water.. Yes, im thinking of what oyu are thinking :) Fire Co2 in you room by pressing a botton 2 times a day :) Rating: 5
