yea the worst you can do is put wet stuff in to jars too early. They have to be in a drying room for almost 7 days at least. After that - they are all piled into a box, and the top left open, still in the drying room. You should notice that some buds get moist again. You want a balance between moist and too dry. If the pistils dry white - you dried too fast.
When you do jar - you still monitor it every 8 hours, if it gets too moist (don't forget - ambient air is almost 90% humidity in michigan summer!) take them back out of the jar and back in to the drying rack. It is a learning process, again - varies with strain types.
if you sell it - its not medical grade so you better tell medical patients it has mold. Its offensive if they have to find out themselves.
