CO2 packages, bong rips in the grow tent

Forcing a plant to inhale the carcinogens of its cousins. ....... does the increase in CO2 make a difference .

Or are propane and time release methods the only kind of viable CO2 absorbsion ?

Will added CO2 in my tent really make a difference?

Added co2 is awesome.... as long as you can keep it around this means a well sealed room a tent doesnt hold the co2 well, you will blow thru tons of co2 trying to maintain beneficial levels, the lil bags are a joke go breathe deep on your plants for 30 seconds an youve pumped out twice the co2 those put out all day an thats if tou believe the mfg.
I have a co2 sensor an stacked 4 of those bags sround it an ot registered aboit 300ppm pretty much atmospheric levels

Could potentially blow up your tent at 3000 ppm

Dude you need to do some research if you plan on using propane so you don't end up in the hospital, then on the News, then in jail. In that order.

Propane for me is out of the question. lol
