having temp problems with fans and aircooled

ok so i have a small grow space 4x3 ft and i have a 600 hps air cooled with its own fan at 440 cfm another seperate fan for exhast thats the same cfm prob alot lower with my homemade scrubber but still blowing air and a booaster fan for intake but my temps are still high and i dont know what to do i think my plants wont be that bad since there is lot of air movement but cant figure out why its so hot any suggestions

Get air from outside and run your lights at night.
Sounds to me the only way you are going to cool that down is to cool the intake or port an ac in there.

check out this thread.. i helped a guy with a similar situation, hope its helps you to man https://www.rollitup.org/newbie-central/247188-temperature-difficulties.html#post3139710

just get small fan and point directly on bulb and check temps again after a shift of light to see!!

thanks for imput guys already bring in fresh air for cooltube but im growing in a shed not inside a house so i wish i could have lights on at night but cannot will blow up on flir no protection at all

There is a guy on here that lives in texas and grows in a shed. cutman.
he uses an air conditioner. I think its 8000 btu.

yea i have one but havent wanted to use it due to engery cost and i have it in my sons room i may wind up using it and use that as my exhaust only but rather not thanks for imput i figure that would be my only option

I ran a 600 and a 430 in a 6x6 and I could not get the heat down now I just run one 600.Ive ran 2 -430s all summer due to heat.I use a stand alone 7000 BTU Ac unit with a 6 inch vortex pulling oder and heat out the room I also have a 4 inch in line TD series fan to pull heat off my bulb.I also pull cool air in with a small 4inch duct fan

My Ac was about 300$ at lowes or home depot, it sure beats the hell out of heat stress
