"The dryer the higher" thats what ive always gone by.
If it were vaccume sealed wet, it will mold. Put it in a brown paper bag and open once a day or so. or lay it out on some cardboard. once its dried out store it in glass. I kept some killer skunk for over a year in a non vaccume sealed jar, and broke it out for a birthday. it was pretty tastey. once you have it in glass, if your looking for really long term you could put it in a freezer. I would never put any herb in a container with a carrot or lettuce or anything else for that matter. It cant be too dry.
you make a good point, but if its airtight the moisture will have nowere to go. wont the vaccume bag fog up? its sucking out the air not the water.. either way dry your herbs out and put them in glass if you can.
