i agree with every thing except the $2 hygrometers on eBay. i got a caliburIII and i paid $18.95 free shipping. it will fit in every size mason jar you will want to cure in.
i hang dry for 3 days on the stem.
then i cut buds off stem and place in jar for 24 hours. it lets the moisture redistribute from the inside to the outside.
after 24 hours i remove from jars and dry on a tray for a day or two. depends on how big the buds are and how much moisture is still in them.
then i put back in jars.
then every 12 hours you "burp" the jars for 10-15 minutes. it releases the extra built up moisture/funk. too much and you will ruin it.
also, when filling jars, DO NOT fill all the way up. i heard about 3/4 is perfect. with the bigger buds i place them in bigger jars and only fill up half way.
here is the hygrometer i purchased. i prefer one per jar. but you may be able to get away with just one and a bigger mason jar. just do not fill it up more then 3/4.
