i may not understand but u say your going to put fresh buds in a jar and you dont want them to mold? u have to dry them somehow before u jar them even if their not totally dry u have to open them for at least 20 min. or so a day to let out the "sweat". dont cook your bud it fucks it up. try a water cure this can be done in a few days. go to overgrows dryin/curing section. peace
