I bought a CO2 tank yesterday. They didn't ask any questions, or ask to see an ID. The tank was $175, filled (~2 months' worth of juice), the delivery system was $150 including the timer, and refills are like 20 bucks. Do yourself and your household a favor!
stinkyattic Reviewed by stinkyattic on . Co2 Furnace question Ok I have done hours of research on several sights trying to find out about using a furnace to produce co2 getting no clear answers. My question is simple, does your furnace running blowing hot hair into the grow room produce co2 on its own? Does anyone here do this? For me it would be alot easier to buy a programable thermastat and set up a co2 program than to buy bottled co2 but the guy at the hydro store said furnaces may be designed to remove the co2 they produce.
