It is going to depend on the temp of the surrounding rooms. If it's pulling in relatively cool air, you should be fine. Otherwise, you might want to toss a small fan intake.

it depends on how hot your grow room gets. but i'd say put one in anyway because the wind inside the grow room will make your plant's limbs and branches more stronger.

i would totally get an intake even if temp is ok.. just to replace the co2 in room.. like a 40 -50cfm will do
