if you put them in mason jars then try wetting the top of the lid before closeing them.. if you do that for a few days they should start to get moist... or just put some lettice in with it.
i used tupperware type dishes dampen a couple paper towels put them over the opening then snap the lid on the buds will draw the moisture from the towels. the mason jars mentioned would work to just according to your preference. good luck with it
I've seen quaps ruined in under 12 hours from an 1/8 of an apple.
Also.. You're mangling the taste by using fruit or bread. Bread gives off alcohols, and other things you don't want in your bud either. And don't use carrots, they're just as prone to mold as apples.
If you absolutely have to use anything, get a very very fine mister that is clean, and take one bud, lightly dust it a few times, let it sit for 10 minutes, hit it again, and put it back in the jar with the rest.
Rotate it a bit over the next few days to make sure the moisture spreads evenly, and repeat as necessary, just don't over do it, or you'll be asking for mold.
I could cry at how many times, I've seen folks ruin a 1/4 pounder... NO CHEESE ON MINE PLEASE!
