Hey guys just wondering what co2 ppm you guys are using in sealed grow room for vegetation growth. First time running a sealed co2 room I’m currently sitting at 1000ppm and 82f 70rh, using 6x spider farmer se7000 leds

"CO₂ is a low-cost input and the leaves saturate at about 1200 parts per million."

Thanks for your input. I had conflicting information during research. Some say 600-800 and others 1200 during veg. Dr Bruce mentioned 1200ppm but is that applicable in veg or only flower

You only need 1200ppm if your running at 85F or above. I wouldn't recommend it. In my experience anything over 78F after week 4 of flower effects bud quality. 800ppm is fine for both veg and flower, unless you need to skimp due to money. I usually cut my CO2 ppms down to 400 and the temps to 75F the last 2 weeks of flower.

Thanks for your input, I have tried the higher temps and higher humidity my plants did not respond well at those temps I’m finding 80f 65% humidity to be the sweet spot, was just not sure on co2 ppms I have it set to 900ppmB965F761-9158-4C88-A311-1DC4BF568AD3.png
