I've had good success using a 1" square piece of paper towel and a few drops of water. Shake paper towel until it stops dripping, then simply stick it on the inside lip of your cure jar/container. One or two applications works wonders with no added funny taste (like lettuce!) In a perfect world, properly slow drying buds is a simple task. In the middle of winter in this Delta region (where I'm currently at) Tule fog and a wet week made it very challenging to slow dry and not worry about mold/mildew problems. I lost half of a grow to this problem once before. It's better to re-hydrate crispy pot than to throw mildewed pot in the trash.
