    Co2 and vpd?

    Well, I did not use "food grade" CO2. Harvested 918g off 4 plants, from seed to harvest 17 full weeks. I'm happy with those numbers, im sure everything 100% perfect, I could have yielded more. My grow will never be 100%, so these numbers are great for me. Thanks to everyone that took the time to...

    Thanks. Autopilot has worked well so far. I dont care for the lights on it, but hasn't seemed to cause any problems yet.

    Co2 and vpd?

    I attached several pics( don't mind the clutter, cleaning up veg room at the moment). Again everything seems to be healthy, two more days will be the beginning of 4th week of flower. The lower temp/ higher rh is room air, the higher temp/ lower rate is at canopy level. My current leaf temp is...

    Co2 and vpd?

    You are correct, everyone should do this. Thats why I asked the question. Without co2 my plants were healthy throughout grow, I would average anywhere from .85 to 1 gram per watt cured. I try to strive for perfection. Again, if I can get more yield, denser buds with CO2 at same cost why not...

    Co2 and vpd?

    Gotcha. No issues here either, other than am I wasting CO2. I do have a sealed room. Just keep reading about growth potential with co2, I live in a state with plant restrictions, so if I can get 10 to 20% more product with same resources, why not?

    Co2 and vpd?

    Been growing for about two years now. Just started co2 recently, I understand that my temps need to be 82 to 85ish to take the most advantage of co2 enrichment. Is that room temps or canopy temps? Currently running 79 degrees in room humidity around 58 percent, canopy at 84-85 humidity much...
