Boveda 58% Humidity Control

Boveda 58% Humidity Control will add or remove moisture within your storage container to maintain a specific relative humidity level. What allows Boveda to do this is its unique ingredients and a thickening agent contained within a reverse osmosis membrane produces a 2-way humidity control.  Maintain optimum humidity to prevent mould from forming or over dried or too crispy product.

Boveda 58% Humidity Control is made from a combination of salts and purified water, so it is completely food-grade safe.

Boveda Humidity Control Sachets will lock in the moisture content by regulating the humidity inside your container. With that moisture locked in, weight loss is eliminated due to moisture evaporation, helping to maintain quality. Boveda will enhance colour, aroma and taste.

The life of a Boveda product depends on how hard it has to work. The more moisture it has to give up, the harder it has to work and the more it takes away from the product’s life span.  You’ll know it’s time to replace Boveda when it’s no longer pliable.

Boveda’s humidity control packages can be used for electronics, premium tobacco, food, music, medical devices, pharmaceuticals, and herbs.

It’s impossible for Boveda to over-humidify beyond the RH on the pack. That’s why our usage instructions talk about minimums, not maximums. There’s no such thing as using “too much”. More than the minimum will just last longer.

Boveda doesn’t need to be activated or maintained. Once the Boveda pack becomes rigid, it’s out of the water and needs to be replaced. This could mean weeks to years, depending on the package or container, how much the container is opened/closed and the ambient environment.

Boveda is the safest way to keep your product fresh and maximizes Terpenes.

8 Gram Boveda – up to 28 Grams of herbal weight

67 Gram Boveda – up to 450 Grams of herbal weight

Below are recommendations for the various humidity levels: These recommendations are dependent on how dry the herbs are when placed in airtight containers together with a Boveda pack. Boveda recommends drying to around 11% before placing into airtight containers with Boveda packs.

58% Relative Humidity
High humidity climates i.e Cape Town (Winter), Durban (All year)
Vaporiser users seem to prefer the 58%. Apparently, it makes it smoother.
If herbs that are not dry enough are placed into a jar, the 58% will be more effective at dehumidifying the jar.

All herbs work beautifully but some will react differently to the different RH level. So testing is the best practice.

One more thing to note. One should never mix 58% and 62% in the same jar, as the packs will work against each other and run out very quickly.

Boveda acts on the environment around it. By adding and absorbing moisture, Boveda keeps the contents of a sealed container at a precise relative humidity (RH) level.
