When I first started growing, I'd simply hang my harvest on a clothes hanger and place it in the next room (cool) with a fan lightly stirring air around the buds. Now I dry inside a large plastic tub w/top...4 small wire running parallel attached to each end or side so buds will hang upside down......a piece of screen attached for a "cot" type layer for popcorns.....One of my dry=bins has 2 80mm pc fans pulling air from holes drilled in the other end....the other has a 120mm fan pulling with well placed intake holes....both are exhausted into my tent where a carbon scrubber runs full time. These dry boxes are inside an area of appro 16-20% humidity, avg 65f....Slow dry..... 10-12 days for a thicker bud.
Something interesting I found out by accident...accidentally left one of the tubs outside 2 day &over night with freshly chopped buds...it was 10-15 deg....froze the shit out of the buds, turned all of'em purple....freeze dried makes the buds draw up and become hard little nugs but was some very good weed! All my friends ask "got anymore of that purple bud"....unique in color although it's potency was the same as its sister dieselryders.....
Anyway you do it, have a breeze stirring around the buds, cool breeze preferably and you'll be fine.
