ok here's a status update: I've installed a garden hose going from my computer room to my basement, and so I sit and blow into the tube to get co2 downstairs I plan on making it one up and putting a buffer of about 10-20 garbage bags tied together... since I'm not *always* here at the screeen and so I can store some for lights on period ... then, I can even attach a fan to the garbage bags to pump in co2
