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

    Sure, IF DONE PROPERLY....the byproduct of burning propane is Carbon Dioxide and some water vapor....Rigging something up can cause carbon monoxide if there is not enuf oxygen available to COMPLETELY burn the propane...but remember too, your hot water heater is not constantly running...just the pilot till the temp falls below the desired setting...
    They make CO2 propane generators that work great and throw off VERY little heat....

    The more carbon in the source material the less is needed to achieve a given ppm level of CO2.

    Someone recently mentioned the use of methyl alcohol. As a liquid, it's potentially easier to work with.

    Another important point to consider is that the baseline saturation of the atmosphere is now 410ppm of CO2, thanks to decades of fossil fuel usage.

    CO2 is typically only needed in completey sealed rooms and large set ups...a typical closet garden with GOOD ventilation, really doesnt need it...I have a 5ft by 4ft closet crop PACKED wall to wall...I have a 700+ cfm exhaust fan....doesnt need CO2....If your borderline with good exhaust, try a fizz pot...I have used a 5gal bucket, 3 inches of white marble rock in the bottom (calcium carbonate)..fill bucket 2/3 with water....Put 2 holes in the top (about 1.5 inches each)....rubber stopper in each...one of them has a hole thru it for a 1/4 tubing (tight fit) the other will be used to dump a half cup of muratic acid into (quickly replug it)...the reaction boils the water with CO2, which oozes out the tubing, wired to the back of one of your circulation fans...It produces a BUNCH of CO2...
