Hey, Im growing this skunk101 plant in a small grow box, the temps usually get out of hand when the lights are on for 24hours, im using a 45watt CFL, and another 27Watt CFL, i have 2 pc fans hooked up 1 at the top blowing air out, and 1 at the bottom suckin air in, even with these contantly running the temps get to about 100F when the lights on for 24hours. The leaves on the plant are starting to point up in the air, and the lower leaves are starting to get really yellow. So do i have a heat problem or what? here are some pictures i took with my shit webcam sorry for the bad quality. I really dont want this plant to die so please help me out thanks.
