i have 1k watt light temp is 88 ish with a 8 inch 500 cfm fan and a 4 inch 80 cfm fan pullin hot air from light to attic why isnt this enough to get job done??? fans from home depot is this not enough cfm? please help
1000 watters are very inefficient, therefore alot of the wattage is converted to heat. There is one reason why the heat build-up- you're not exhausting enough air with the 4" fan. It sounds like you need alot stronger exhaust system.
Possibly try a cool tube set up, they are the most efficent when tryin 2 cut down on heat build up in the grow area but I woulnt worry about it if temps are 88F good luck happy growin+smokin peace
