imo it is better to pull than to push. ive read a lot of threads in here that people have temp problems and it was from pushing air. all my set ups were pull rather than push and it kept that light soooo coool! also since it was pulling air through the lights it was pulling the hot air + stale air out while i just had another hole in the grow room for a passive air intake. its an ostburg fan too.
