Overdried buds. Can I save them? Got 4x 8 tier mesh hangers of buds

Boveda 2-way humidipaks are definitely the easiest way to go. Sealing up with 'anything' that adds moisture is a less controlled, but viable option if careful and check to make sure you don't go too far the other way and grow mold. Don't buy the integra boost. they don't maintain the RH promised.. they are garbage. getting them back to a proper level of moisture for storage will help for sure (going beyond and re-drying is not necessary and should be avoided). It won't crumble to dust when you break it up and shouldn't be as harsh to smoke.

I’d jar them up and keep the jars sealed for a couple of days to see if any moisture comes back in to the buds from the stems. There is typically more moisture in the stems after the dry and I’ve had some success with this. Other things I’ve tried like Boveda packs or orange peels never really seemed to work. If all else fails you could always make hash or edibles. Good luck 👍

Jar it then add bovieda moisture packs 62 percent rh keep sealed and see.

Terp you loose while drying are lost forever. You can still smoke the weed, but dont expect a lovely taste. Of course you could try to humidify and dry them, but you will never achieve the same result of taste.
