When Should I Consider More CO2?

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 ! 🚀
