Hydrostone Terracotta Humidifying Stone (3 Pack)

These terracotta humidifying stones are no joke. They are the size of a quarter and easy to use.

The disks are mini sized, but they really work! I added all three to a container of rock hard brown sugar. The sugar is super soft now. Highly recommended!

Works perfectly. Just don't leave in morw than 15 minutes or so. Enjoy!

Used to hydrate dried herbs will kept in jars. Herbs molded. Certain I did something wrong here. Wish it came with instructions or something.

I was a little skeptical at first. About these, but if you manage the humidity carefully, it could make your stash last a long time

Thankfully these work great. Certainly didn’t need this many but better than bread crumbs in my brown sugar trying to keep it soft!

I was skeptical at first but after reading many positive reviews I had to check them out. I can attest they are effective, but they don't work the same as a Boveda or a similar 2-way moisture pack. I use them for cannabis I grow and cure that has dried too much. Like others have mentioned they work very quickly, meaning the water that's in the stone will evaporate quickly. This means if you put it in a closed jar with some dried out plant material, you will indeed see the RH % in the jar shoot up fast, but the moisture doesn't absorb fully into the plant material for some time. So, if you remove the stone quickly from a jar with, say, 1 oz of dried out plant material, the RH will drop again pretty quickly as the small amount of water vapor is absorbed, and you're back where you started. The upshot is, if you have a moderate amount of buds or plant material to rehydrate, you shouldn't just pop a fully wet stone in a jar and leave it like you would with a Boveda, because the water evaporates into the air quickly and may not fully absorb for a while, and the RH may get into mold territory in the meantime. Rehydrating very dry plant material usually takes some patience, and I don't recommend more than a few drops at a time on the stone. Let the water fully soak into the stone (a few seconds), place it in the container and give it time to absorb into the buds before rewetting, keeping track of the RH with a meter. It definitely works, but it's a little more work than a moisture packet to get, say, an ounce of dried buds stabilized at 58% RH in the jar, but the nice part is these stones can be reused over and over, and they're very cheap. Highly recommended, especially if you're a grower and, like me, you don't like buying and later throwing away all those moisture packs.
