But I have a little problem with the heat in my tent, its a XL tent (1,2 m x 1,2 m x 2 m) my setup is a little carbonfilter, i think its a 750 "fan" the filter is mounted on, then I have a big fan, which is pointed directly on to the lamp, but still the temps are between 24-28,7 C. with the light on... And the other thing i dont really cant figure out is how the h*ll I should mount the carbonfilter so its hanging over the lamp, these ironbars thats in the top cant really withstand the weight....! thats fo sure... I know theres a lot of tentgrowers outthere, whats our setup ?? ! H E L P M E !
