PICK YOUR OWN
I bought the the exhaust CO2 bags. I will be running a sealed room. I am depending on the plants to self regulate the CO2 generation from the bags. Plants will smother
In A room of oxygen. I’m not so much trying to kill it on CO2 with weight. I’d like to have the peace of mind that the plants are not stressed out due to a low CO2 level.
You do you. Dont let others try to tell you what you need to do with your setup.
If they can harvest half a pound of weed in a 2 square foot area with tap water, 100 ppm CO2 and an incadescent bulb then more power to em. But obviously if you want shorter flower times, increased yield, happier plants while in a sealed room then you do your CO2.
