If i could find a fan, i would love to, but my odd bulb placement won't let me fit anything I've seen locally... the closet's temps are constant 72-76 when lights are on so i'm not stressing at this point i just don't want accumulated heat. Its an unused room that sees no ambient heat and its 30F outside.
I feel the bulb is keeping these ladies happy! I doubt the fan is doing anything but moving random air
, I'm adding another 600w HPS horizontally when my other soil girls are done, it will have a cool tube with a vortex and controller, i'll staple the ducting as close as possible to the vertical burning MH and regulate temps and cool both lights.
