Keep smaller amounts of herbs fresher for longer with the Boveda 62% 4g humidity pack. This compact Size 4 pack fits small airtight containers, stash jars, tins and travel cases, giving you simple 62% RH humidity control without soaking, charging or daily checks.
The 4g pack suits up to 14g, or 1/2 oz, of material. Once you place it inside a sealed container, Boveda’s two way humidity control reacts to the moisture level around your herbs. It releases or absorbs moisture as needed, helping maintain a stable environment inside the container.
This makes the Boveda 62% 4g pack a practical choice for stopping herbs from becoming too dry, brittle or harsh. It also helps preserve natural aroma, texture and terpene freshness, so your herbs stay in better condition between uses. For personal storage, sample jars or smaller amounts, it takes the guesswork out of herb storage.
Dry herbs can lose aroma, flavour and texture quickly when stored without proper humidity control. The Boveda 62% humidity pack helps protect against over drying by maintaining a steady 62% relative humidity inside your container. It is especially useful for small jars where moisture levels can change quickly once the lid is opened and closed.
Using it is straightforward. Open the sealed wrapper, place the Boveda 62% 4g pack inside your airtight container and close the lid. There is no need to wet the pack, activate it, refill it or use a separate humidity device. It works quietly in the background to help keep your herbs from drying out or holding too much excess moisture.
Replace the pack when it becomes firm or hard to the touch. In a well sealed container, a Boveda 62% 4g humidity pack will usually last around 2 to 4 months, although this can vary depending on the freshness of the material, how often the container is opened and how airtight the storage is. For larger jars or bigger amounts, use multiple Size 4 packs or choose a larger Boveda pack for better coverage.
