you have 8 square feet not 64, height does not matter in area.
but yeah your light is good so i would try to get a new fan. the one i linked you will work great in a area that size. i don't know the type of reflector you have for your light, but if it is a kind you are able to attach duct to it that would cool it down even more
stickyicky07 Reviewed by stickyicky07 on . Ventilation ideas. Ok, here is a pic of an idea for some light baffles i am thinking about building, since i currently have no intake for my ventilation. It is a light baffle system, where i willl be cutting out 4 square holes 4" x 4" on the bottom of a wall in my grow area and cover them with baffles i will be making, most likely out of tough cardboard. Take a look tell me what u think? Rating: 5
