Description
Two-way humidity control that protects cured flowers
Boveda packs are a two-way humidity control that buffers moisture in both directions, holding cured herbs and flowers at a fixed relative humidity without any refilling, activation or maintenance. Cured flower stored loose either dries out and loses terpenes, or sits too damp and risks mould. Boveda's membrane releases purified water vapour when the air is too dry and absorbs it when there is too much, keeping jars and containers in the sweet spot on their own.
Key Benefits
- Two-way control that adds or removes moisture based on temperature and conditions
- No maintenance with nothing to refill, activate or top up
- Mould prevention as it will not over-humidify your stored product
- Safe on contact with proximity and direct contact leaving herbs undamaged
- Purified vapour, releasing only clean water vapour
- Holds 62% RH, a steady level for stored herbs and flowers
- Trusted by professionals for long-term storage
Flowers drying out too fast or turning mouldy in storage?
Uncontrolled humidity is what ruins a good cure, driving off aroma or inviting mould. A matched Boveda pack locks the container to one relative humidity so the flavour, aroma and texture you cured in are the flavour and aroma you get weeks later.
How to Use
- Choose a pack matched to the relative humidity you want to hold.
- Drop it into the storage jar or container alongside the cured product.
- Leave it to work with no activation needed.
- Match capacity to your load: a 4g pack maintains up to 14g of product; a 67g pack maintains up to 1lb (about 450g).
- Replace once the pack has fully hardened and no longer feels pliable.
