HOW BOVEDA WORKS
4 gram packs are the appropriate size for smaller enclosed spaces, like our StashhJars. Boveda is scientifically engineered to maintain a precise relative humidity in an enclosed space, and our 4 gram size is available in 62 percent RH. We recommend using 1 pack for up to 14 grams and flower and 2 packs for between 14 grams and 28 grams of flower.
Each Boveda consists of a specially prepared saturated solution of pure water and natural salt. This saturated solution is contained within a water-vapor permeable "reverse osmosis" membrane. Within an enclosed container, Boveda maintains a predetermined level of (RH) by releasing or absorbing purified water-vapor as needed through the membrane.
