    So a friend of mine that used to grow back in the day told me he used to run a airline from above his propane hot water heater to collect co2 from it? Anyone ever hear of this?

    you'd have to hook it into some type of controller so it shuts off when ppms get high.

    Cool what ppm is good do you know?

    rkymtnman Well-Known Member

    kinda depends on how intense your lights are. and temps. and RH%.

    no more than 1500 ppm for sure.

    i run around 1000.

    i'd be curious of what else is in the "exhaust" of the water heater. probably some shit you dont' want in the garden

    buy a tank, a controller and be done with it. or a burner if you have a big room.

    You have to be concerned about CO. Gas water heaters in a closet vent the gas outside, not in. If your grow room is connected to living space, I wouldn't do it. Get at least 1 CO detector in the main area/hall of your house either way.
