Greengo Humidifying Stone Review

Greengo's Humidifying Stone is made from clay and offers a simple yet affordable way to prevent bud from drying out.

If your bud is always drying out before you can finish it then today’s review will be of interest.

It’s the size of a quarter, under 3 dollars and made from a blend of natural terracotta clay. The Greengo Humidifying Stone is an effective and simple way to prevent your herb or tobacco from getting dry. They’re produced with minimal impact on people and the environment.

We thought Greengo’s unbleached rolling papers were good so it made us curious about their other accessories.

The quality of this product is what you’d expect when you pay a couple of dollars for something.

Made from a clay compound and lasting several years, there’s very little to complain about when it comes to quality of construction. The humidifying stone is shaped like a clay disc approximately the size of a quarter except maybe 3 or 4 times as thick. It’s exact dimensions were 30mm diameter and 6mm height.

You can use this product a few ways depending on how much moisture you plan on adding back into the bud. The first option is to simply add 2 or 3 drops of water to the stone as this will produce a more reserved amount of moisture compared to running the stone under the tap so it absorbs as much water as possible. You’ll see that the moment a drop of water hits the surface it’s absorbed nearly immediately.

We recommend adding just a few drops because adding too much moisture can be just as bad as not having enough.


Greengo’s Humidifying Stone is available online for between $3 and $4 per unit which is reasonable when you factor in the re-usability.

In addition to their low cost, these stones are made to be used hundreds of times so in theory there shouldn’t be a need to replace it for many years as long as you take care of it. When you consider the price, product lifetime and how nice it is to convert bone dry bud into something more enjoyable it an easy decision to grab one of these just to have it on hand.

Since high school my friends and I have been recreational cannabis users so we decided to start Merry Jade after legalization in 2019. We review and photograph the different products then share them on this website. The rating system we use is called “SAFE” which stands for Smell, Appearance, Flavour and Experience. Each category gets a score out of 10.

Have your say!
