Boveda Humidity Control 58% 4g


R0.25 Cashback

When do you use a Boveda humidity pack? Whenever it fits in your cannabis storage container. Boveda will never humidify beyond the RH on the pack, so there’s no such thing as “too much”. You want to think in terms of using at least the minimum because the more you use, the more efficient Boveda works and the longer they last.

Boveda bags are commonly used in mason jars and large bags. They can last 6+ months depending on how often the container is opened, you’ll know it’s time to replace when the entire Boveda begins turning hard.

Boveda provides the cleanest and most purified humidity of all other products available on the market today.

Note: Do not mix Boveda RH levels within the same container, and do not use Boveda in the same container with other humidification products. They will fight against each other and reduce the efficiency of the Boveda.

Before Boveda, it was difficult, if not impossible to control humidity for moisture-sensitive products, like cigars, cannabis and wooden instruments.


Starts with a frustrated cigar lover who also happened to be a humidor maker. Keeping his cigars properly humidified was a tough job. That job was labor-intensive. That labor didn’t always work. It was the ’90s and he was limited to distilled water and sponges or distilled water and shot glasses or foam and chemicals. (Some people still use those one-way humidifying methods. We don’t know why. But that’s another story.)

So he called a guy to solve the problem. That guy was Dr Albert Saari, a retired General Mills chemist. Saari found the answer in salt. Turns out salts keep a fixed relative humidity (RH) level. Supersaturate those salts with pure water and they humidify the surrounding air.

So Saari called a guy he knew, Robert Esse, a General Mills packaging specialist. Waterproof packages, no problem. Packages to let moisture pass in and out, never been done. So Esse found a material that had a high water-vapour transmission rate but stopped salt. Bingo! Let’s patent the packaging. (And patent it many times over around the world.)

So the humidor maker then called Sean Knutsen and Timothy Swail, two friends with business and marketing backgrounds to form an entirely new company to bring this simple, yet remarkable invention to market. And in 1997, Boveda (then Humidipak) was born.
