What’s good friends!? I’m trying to figure out what is my best route for putting Co2 in my 5×5 tent. I have a carbon filter in my tent, I have a controlled humidity level (keep it at about 60% during veg and 48% during flower), I’m running an HLG 260w v1 duo quantum board DIY kit, and a 450w viperspectra. I feel like the next thing is Co2 supplement. The pictures I provided are what I’m considering for use, any other options are welcome.
