I have a 40"w x 43"l x 82 1/2"h,(approx. 82 ft./3) insulated enclosed space inside my unheated outdoor shed. I live in the Northeast U.S.. Winter temps can go well below freezing (32F./0C.) I planned on using a 400w HPS/MH light, My exhaust fan with carbon inline filter is rated for 65cfm. .I have a 28 in/2 inlet opening with damper, Can someone please tell me what my grow room temp will be. And would it be o.k to not have a constant air flow exhaust working ,but hook the exhaust system to a temperature controlled device, that would only come on when temp gets to high inside box.. I was thinking of setting exhaust temp to come on at 70F. and turn off at 78F. Or will grow box ever get up to ideal temp of 70-78F. ????? Getting frustrated with little or no info on this subject. Thanks.
