Hydrostone Terracotta Humidifying Stone (3 Pack)

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.

My dealer told me about hydrostones. He told me they could revive dead flower. I was skeptical until I got them. OMG, it turned my crumbly flower you could crush to dust between your fingers into nice, fluffy, high quality flower again. I'm just mad I never knew about these before. If you smoke flower, you NEED to own one of these guys. I promise you won't regret the purchase.Just follow the instructions, and don't leave it in permanently. A few hours, overnight at most. Don't let your stash grow mildew. Just revive your dying stash.

Get them! They are life savers for larger amounts soak for 5min for smaller half’s or OZ wet and dry throw it in and burp it thru out the day

These Raw clay hydration stones are like magic for keeping my weed fresh! Just soak them, toss one in the jar, and my buds stay perfectly moist and potent. No more dry, crunchy flowerThese stones really do the job of keeping everything at the ideal humidity level.The 3-pack is a solid deal, especially for anyone storing multiple jars. Sure, you need to re-soak them every couple of weeks, but it’s a small price to pay for that fresh-off-the-plant budsPros:Keeps weed fresh and potent.Great value with the 3-pack.Super easy to use.Cons:A little maintenance (just soak them every now and then).Final Thoughts: If you’re serious about keeping your buds in top shape, these stones are a must-have!

These work really well in both pipe and rolling tobacco.

Keep your product from drying out too fast.

Great product, hasn’t broken or chipped. I’ve had it for over a month now and it definitely does its job as intended, if you need your herb moist in less than 30 minutes then this product is your go to. Definitely recommend.

Tiny. I will need to use all 3 in my brown sugar. No info on where these are manufactured, just "to be sold in United States only."
