i recently purchased a 65watt compact flourescent from home depot i am having a problem using it however becasue my grow box is farely small about 3 1/2 feet high and 4feet wide i have one exhaust fan but no intake could that be my problem. the temp is around 100degress faerenheit.
oh and to those who doubt the 65watt flourex bulb let me just say that is does indeed put out over 8,000 lumens and is very efficient for vegging
u will need an intake as well to keep the air flowing around the box
thanx i figured that was probably my problem what size intake fan do u suggest to lower the temp about 20 degrees
um im not to sure as i dont use a fan to control my temp but only to circulate air as my box lets heat out pretty well, id sugest getting one roughly the same power as ur outake to keep the temp constant and not declining or rising. im not to sure what size u'd need to use to reduce by certain temps tho. gud luck
thanx for the info i now have a three inch intake fan and i put a air conditioner in the grow room so the intake is sucking in some cold air my temp last night was 83 degrees do u think that'll be ok?
the only problem i might have is i might need to water more often to compensate for the evaporation
