ok got back from lowes, we got the $12 bathroom exhaust fan, its only 50cfm of air, the 70cfm one was $27, since i already ordered a 80cfm air duct fan from ebay this will do fine for this closet till that one gets here. this one might end up in the veg room but with the cfls temps are about 72 degrees with no air movement, so that room is really fine.
we measured our cubic feet and we are only at 49cf, and we installed a 50cfm fan in the room. so in thought, that fan will replentish the entire air supply to the room in one minute. for air intake as of now we just drilled two 2 1/2 inch holes at the bottom of the door, they have two PVC drain pipe covers on them and look pretty discrete in the bottom of the door, since we built the shelf in there it blocks most of the light to the bottom of the closet.
these are designed to be installed in the ceiling and have just a square part with vents (not pictured) but it requires you to cut a 1 foot hole in the ceiling. instead we just mounted it to the wall, then used ( dont laugh ) intake tube from a car and ran it thru the ceiling, this way we only had to drill a three inch circle thru the ceiling, since we rent and all. now minus me hitting a ceiling brace on the first shot, and having to drill a second hole all went very easy on install. now on the top of the closet on the craw space the tube is attached to a longer dryer vent style hose that runs it straight OUTSIDE the house thru a 3 inch vent pipe in the roof that was discovered when crawling up there.
the fan has a regular plug on it so i just plugged and extension cord into it and hooked it to the power strip thats hook in with the lights and timer. couldnt be easier.
check out the readings on the temp and humidity meter now, top temp 78% thats above the shelf where the plants are, 69% is below the shelf where we store the water (its placed up top to warm before a water) and a nice 52% now showing for humidity. these are much nicer numbers for my babied then the blistering 100 degrees they woke up to this morning.
