Hey SC, I was just looking to see how our setups differ and noticed you are not running Co2 yet? Are you planning on adding it? All you would need to do is get an A/C unit and you would be set. You would be able to saturate your girls. I believe cannabis can use anywhere from 2000 to 3000 ppm of Co2. Fresh air is like 300 ppm. That is the weak point in nature. We loose lumens bringing plants indoor but we can make up for some of the loss with a Bottle of Co2. Speed up your harvest AND grow bigger and better buds. A piece of equipment that pays for itself is a good investment. I would like to see you get as much as possible from your effort. This stuff is not growing itself.:weedpoke:
