I have smoked right out of the bag but its just the little popcorn buds.
Not the best of course but no grass taste,actually tastes pretty damn good,you need it,you need it.
When I first jar at around 65 % from the bags,yes the % will go back up from inner moisture coming out.
Then I simply dump them back out for couple hours and try again.
I can usually get my % right and holding within a week or two.
I also put a vacumn in my jars after I'm stabil. I don't use any packets and I just checked some erb from last November and it is still in the 60's.
I open every couple weeks to refresh a little and seal right back up, this works great for me as I try to keep my erb cycled for around a year.
Works great for me and I'm not spending money on packets. Now for longer than a year I would recommend them, but I'm cheap and poor and old.
I don't have time but chester is right,the slower the better.
edit: some people like their erb dry,some moist,i prefer around 50 % in a pipe,dryer in my arizer.
