When Should I Consider More CO2?
Northostarted grow question 4 years ago
I flower my plants in a mylar lined box, roughly 2' deep by 4' wide by maybe 6' tall, using two 300W Mars Hydro LEDs.
With that amount of light on the plants, would you recommend more light, or CO2 supplementation, and if so how much?

Hey there northo, basically cannabis works better with more co2, whereas you’re at 500-550ppm canna works better at like 800-1200 ppm . So if your goal is “optimal growing conditions” then you can go ahead with co2 supplementation. I liked using the TNB co2 product more than others . You’re right to mention the light though , it’s probably a more logical investment at first. I see you’re using blurple. What I ask folks is always “what color is the sun?” Try the newest generation of lights : they’re the right color now. A good light will do more for you than extra co2 for sure. Hope this helps ! 🚀

Incredibly low CO2 levelsAfter adding an A/C to my tent I began using bottled CO2 like never before. 20lbs in 5 days. Without adding, my CO2 is at 4 ppm. Yes, four parts per million in the dark. How can this be possible if the air in my house sits at 400ppm? I read that photosynthesis stops below 200ppmSetup. Other
