ok so hears the scoop. area is 1'x1'x4'. plan on using 6-8 cfls, combo of both 26w and 45w. will be makin an inclosed light hood with fan attached to cool it some.. k so ventilation, i was thinking of running a box the size of 80mm fan all the way up the box in one corner with the light cooling attached somewere up high. question is can i run say one or 2 more fans inline inside the 80mm box that goes up the box say one at 1/3 the way up and then one at 2/3 then last one would be connected to the light hood pretty close to the top? if that would work is there anyway to control the 2 lower ones so they only run when they need to ex... say temps get a tad high so the 2 lower fans kick on and get the cab back to normal then shut off? does this sound like way over doing it or even possible? thanks for the help everyone.
