Hello. Colleagues tell me who dealt with the organ...

the brand should have some data on how well it works and how much co2 it is pumping out. co2 is a tool used for experience grower to push their grow to the next level and is not needed by new growers. to fully take use of extra co2 in the tent the plants need to have a lot of other variables locked in, PH, RH, Temps, Feeding, EC, and then the last one if the lights density your giving them. If its not above 900-1000ppfd its not needed. If you have it, prime it and keep going. but I would save your money in the future. Best Of Luck!

Hello, as organoman mentioned, if you dont have a closed system with high heat then it is not useful.

You don't need it unless your ppfd ranges are over 1000. It a waste of money.

Honestly, unless you are growing in a sealed/closed system, using CO2 is largely a waste, as most, if not all of it, will get sucked out by your exhaust fan long before it has any chance of being of any use to your plants. But, I guess it doesn't hurt, so may as well use the bags.
