mobay so how does your ventilation work as far as intake and exhaust I need more detail please cause I'm still having a major problem with the temps. Harddon said that I needed a High static fan but my pockets are extremly low due to the fact that I already wasted a lot of money on the grow and X-mas. So maybe I can get an idea Oh dont forget to mention your cool tube too. Where did you get the cool tube? 1 more question sorry Whats ur temps in the box with the door sealed shut? Thanx
