Thanks everyone! I changed my set-up and am running the fan and filter 24/7 now. I did do a dumb thing though, I nocked the back plug out of the ballest for the light and did not notice for about 30 minutes
I tried something new, where I had my light and big ex. fan on the same timer and a smaller ex. fan (less than 1/2 strength of the big one) come on for the dark 12 hours, mostly done because of the noise. but at about 2 weeks in alot of the leaves went pale yellow. At first I was thinking grow tent gas off but, now I think it was lack of air flow (the girls went outdoors anyway and are now looking alot better) so I too concur with 24/7 exhaust on.
