Boveda makes two-way humidity control packs that hold a precise RH inside sealed containers, widely used by growers to cure and store flower without over- or under-drying.
Boveda was founded on July 1, 1997 in Minnetonka, Minnesota as Humidipak Inc., started by a group that included formulations chemist Albert Saari and packaging engineer Robert Esse, both former General Mills employees. The company was granted its original two-way humidity control patent in 1998 and rebranded as Boveda Inc. at the IPCPR cigar trade show in 2012. Boveda's core product is a single-use pouch containing a saturated salt solution in a water-vapour-permeable membrane. Placed in a sealed container, the pack either adds or absorbs moisture to maintain a fixed headspace relative humidity. For indoor growers, this solves the post-harvest problem of curing and storing flowers at a stable RH, typically 58 or 62 per cent, preventing brittle, terpene-stripped buds on the dry side and mould or harshness on the wet side. The range covers small packs for jars and personal stash up to 320 grams, and larger sizes for bulk totes, turkey bags, and curing vaults. Boveda also partners with the CVault line of stainless steel curing containers. The two-way mechanism is patented and distinguishes Boveda from one-way desiccants and humidifying beads, which only release or only absorb moisture. The salts used are food-grade, and the packs are listed as biodegradable. Manufacturing is done in the United States from the Minnetonka headquarters, and the brand sits in the mid-to-premium tier for humidity accessories rather than competing on price.
