If heats not an issue then propane is the cheapest source to make CO2. Never used the stuff your thinkin of, but I use a very small propane torch in my flower room which is small...can't use it in the summer due to heat issues tho. I just run it for 15-30 mins when I'm home as it can be quite dangerous to leave it alone burning. Using it for veggin is a waste, IMHO. It does make a substantial improvement in flowering tho.

I've been growing for over 9 months and i upgraded everything else to add to my yield. currently Im running at 2.5oz per plant with 4 weeks veg time. I would like to keep increasing my yield and that's what made me so interested in using co2. my local grow shop superior grower supply had a bag of co2 called exhale for 30 dollars a bag that each last about 3 months i believe. i want to buy two bags grow my veg tent to start and another 2 Rating: 5
