In planning phase for new grow..at new spot..since last grow. My ONLY choices r detatched garage or attic. It sucks but i gotta work with what i have. I was leaning towards garage but when i picture it in there..i kno im gonna hear the most silent of fans and whatnot. I live in a very quiet spot..u could hear a squirrel fart in the woods. I live in NY area to give u idea of climate. Grow will only b april-nov..i live on a very wooded lot. House and garage almost surrounded by a canopy of big oak trees so sun doesnt blaze down much..very shady here.not sure what ambient temp of attic will b. Is it possible to realistically have a healthy successful grow in attic here. I will use a tent in either garage or attic. Would using a good 6" exhaust from tent with a T so i can also exhaust the attic work. Attic has no fan now. My tent will have 2 4" axial 112 cfm at top..all passive intakes..and will also have a 6" exhaust from tent with a T also to exhaust attic..duct will run from tent and t to attic vent. I can also keep my photoperiod lights off during most of day. Am i pipedreaming with attic grow like this or can it b done? Thx
