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..
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
some pictures of the clones still 1st week of veg I also replaced the ghetto computer fan exhaust for a 165cfm inline. Just a note it was a little loud and I needed to buy a speed reducer.
Great job man! What soil mix r u using?, & nutes ? I just hung my 1st ever project, everyone has me freak'in on
watching for mold & shit
But anyway would like to try soil this time, any tips ?
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.
