^^Bingo!

It doesn't need to be in a glass jar. Airtight jars aren't good for sealing up and putting moist things in, as that causes mold. You want some air circulation so mold isn't a risk.

I prefer to use slices of raw potato. I find using orange peels or apple peels alters the taste of the weed. Using potato slices doesn't alter the taste at all and keeps it natural smelling, and tasting.

So just in a baggie, for about 6-8 hours, and it should be moist, and don't let the peels or whatever you choose to use touch the buds.
