My closet grow (25"x59"x 96") is averaging around 90F inside with an outside temperature of about 70F ( so venting into the room outside the grow room is no issue as temps never rise outside more than 75F).
I have a small fan near the intake (6" hole) and at the top of the door is the exhaust (4" vortex) i run a cool tube in the room with my 400w HPS (ballast inside the room). My question is why is my room so damn hot?
I have the light 8" above the plants and 2" above the canopy its 90F. Below the canopy it ranges from 75-85F (w/ a RH of 30 at the top and 55 halfway down).
Im thinking of putting a bigger fan and hanging it 5" below the light to push that hot air back and up towards my filter(exhaust is away from the open door) - il try this tonight but does anyone have any ideas on what to do? my plants seem to be doing ok but not 100% (which is what i would like... but dont we all?).
any ideas are welcome!
(I have metal tubing attaching the exhaust hose to one end of the cool tube just in case the vinyl hose melts - i will be upgrading to metal when i get the chance to pick some more up - just so nobody has to bother about telling me its not safe.. the cool tube and the air doesn't get hot enough anyways and its new tubing so it smells so good..)
thanks
