You want the temps to be atleast 60 but less than 80, RH around 40%. If it gets to cold, they will take forever to dry (freezing will damage buds that arent dry). You will also need to have some air movement, as not to cause mold/rot. If you cant hang them place them on a paper bag and rotate and turn them everyday. A proper drying is key to good smoke, dont let you hard work go to waste by not drying them and curing the proper way. There are lots of good reads on here about drying and curing
Good luck: stlmatt
