hey .. id just go to home depot. and get a fan there they have 4 inch to 12 inch fans .. then buy some aluminum vent tube.. kinda like dryer exhaust .. sept u do not want insulated for this because could cause fire and or mold and bacteria.. its cheap .. cost u 40 bucks and u will have a perfect running system.. my light exhaust is at 100+ degrees..

Think I would be better off with a 180 cfm inline fan or will this do? I need to get a digital thermometer -.- I WANT SOME KUSH!!!!

Im running my 400w HPS with a 4in inline fan. Had temp problems but put a nice little desk fan blowing over the plants and light and now its down to manageable temp

Im actually using coco coir and general hydroponics/general organics nutes I would say use LST and FIMM techniques just want to maximize your light as equal as possible.
