twitch Reviewed by twitch on . 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
