lHumidity problems. Please Help!

I've had 2 successful crops in a small walk in closet. I've reinvested most of the funds (remember non-profit) & have set up a 10' X 9' at my partners residence in the garage. The room is awsome with a high celiing, completely sealed & so much air movement that crowding & mold will not be issues this time. Unfortunately I still have a problem with humidity & heat. I'm using 4 1000 watt lamps & am running a 12,000 btu portable A/C unti & a small vics humidifier. The lights are being cooled by running 2 445 cfm inline fans. 1 inline fan pulls air through each set of 2 fixtures & no hot air is being pulled from the garage (just fresh air from outside the garage). The highest I've been able to get the room to is 24% humidity. The coolest the room gets is 70 deg F while the lights are off (18 on & 6 off) & up to 95 deg F when the lights are on. I'm desperately trying to get to a constant 75 deg F & 40% humidity. Please help. I don't have alot of money & can't afford a 1 hp water chiller & 4 ice boxes. Thanks

from what ive heard your humidity can be low as long as yer plants are healthy. mine are currently around the 20% mark and dont seem to show any ill effects. I would be more worried with the 95f than low humidity

if you got it all hooked up like you say you do theres no way possible it can get that hot u need to re-evaluate and see were your mistake is

put the fan were it blows over the lights. with it pulling across you lose cfms
