Greetings friends, I am new here and am setting up a closet 4x6x8. Would like to add fan and carbon filter venting to the attic, with a passive intake from the adjoining bedroom. I am growing with Leds so i am hoping temps in the summer are going to be ok, but only time will tell. I would like recommendations on fan/filter brands and sizes for this size room 4x6x8. Was looking at this combo? 6 x 14 CARBON AIR FILTER PRO COMBO 6 INCH INLINE FAN EXHAUST HV KIT SET | eBay Pro's Cons, or another brand? Price unfortunately is an issue, can't break the bank, under $250. Also was wondering about passive intake size if running 6 inch exhaust. Thanks in advance.
