Keep left-over ICE in freezer. Or just get reg.@ tank? Later
CO2 is heavier than air and by placing your source at root level, you're not going to get any of the benefits. Also, dry ice does not keep well in a standard freezer as it requires either much cooler temperatures or pressure to keep.

Home Made Hey I had ian Idea and just wanted to see what you guys thought....I took a 20oz Paintball Co2 bottle and took the metal hosing from the gun and connected the two together just as if it were still on the gun. then i took a black rubber hose and poked holes all down the side and pluged it into the end of the metal hosing to the gun. If i wrapped the hosing around the top of my grow cabinet and turned the valvue on at the lowest pressure and let it run for about 15 mins a day do you think that Rating: 5
