I dont have any experience with them, and not too sure how exactly they work... But what I would say is be careful using certain things to dry and (de)humidify certain things can leave a taste on the buds that is disgusting and harsh... Such as people who store their weed in a backpack with a dryer sheet or something, that smell from the oils or whatever is on it, will migrate, even through baggies into the bud and you'll smell and taste it. So I would be wary of using certain desiccants and anything other than a regular dehumidifier/humidifier.. which can be found for cheap (or rent the large flood restoration dehumidifiers for a couple weeks from home depot if you have a very large area.
