Hang it in a dark closet. DO NOT put a fan on them. I think that ruins any chance of getting a good flavor during the cure process.
If you are comfortable inside the room, then the RH is probably below 65%. Let them hang until the buds feel a little crunchy with a slight squeeze, then go another day. You are going to need a hygrometer anyway, and lucky for you they are really cheap. If you have a Lowes, Home Depot, Walmart or Target near by, you can pick up the Accu-Rite temp and humidity monitor for about $10.
