@Growin_it, I have not used CO2 in my personal home grow at this point. I have used Titan Controls CO2 equipment/meters in the past. I was recently looking at adding CO2 since I added the P4000 from ViparSpectra. I'm in a tent running AC Infinity ventilation in and out so I am exchanging the air quite frequently. Still not sure how well it will work using a product like Exhale as it supplies constant CO2. Any suggestions?
