Boveda makes the two-way humidity packs that live in the jar alongside your flower, holding the container at a fixed relative humidity so bud neither dries out to dust nor sits damp. It is storage hardware rather than anything you smoke, and it is the product that created the category.
About the brand
The company started in 1997 under the name Humidi-Pak, run out of a suburban house by a group chasing a better way to keep premium cigars in condition. A retired General Mills chemist, Dr. Al Saari, worked out the salt solution; his former colleague Robert Esse, a packaging expert, found the permeable film that could hold liquid while letting water vapor through.
Two cigar enthusiasts with business backgrounds, Sean Knutsen and Tim Swail, turned the prototype into a company. The Boveda name arrived later, alongside a faster-acting pack built to work inside wooden desktop humidors. It means vault in Spanish. Cannabis growers found the product around 2007, and it has been part of the flower supply chain since.
How the packs work
Inside each pack is a saturated solution of purified water and natural salts, sealed behind a patented water-vapor permeable membrane. The pack reads the air in the container and moves moisture in either direction until the space settles at the humidity level printed on the front. Nothing needs activating, and there is no refilling.
That two-way behavior is the whole point. A sponge, a citrus peel or a glycerine bead only adds moisture, and keeps adding it whether the jar needs it or not. A Boveda pack pulls moisture back out when the container runs wet, which is why it holds a number instead of drifting toward one.
What they make for flower
For cannabis the packs come in two levels, 58% and 62% relative humidity. The lower number suits humid climates or anyone who likes a drier, easier grind; the higher one suits dry climates and people who want sticky bud. Both are sold under the Terpene Shield name.
Sizing runs by how much you are storing. Size 1 covers an eighth, Size 4 covers a half ounce, Size 8 covers a full ounce, and Size 67 covers up to a pound in jars, bags or a two-liter CVault. Using more than the minimum is fine and makes the packs last longer.
A pack is done when it stops being soft. New ones flex; once you feel hard spots forming, swap it. Waiting until it has gone stiff as a wafer means it stopped working a while ago. Boveda also sells CVault stainless containers with a holder built into the lid.
Beyond the jar
Cigars are still the home category, with packs sized for humidors and a wood humidor built around them. Guitar and instrument makers ship packs in cases to keep wood from warping, and there is a food and general storage line. A business program supplies growers and packagers direct.
What is changing
The cannabis side of the business is being rebranded as Vivi Fresh, a new look on the same packs. If you have been buying Boveda for flower, that is the name to watch for on the shelf.
The High Rise take
Nothing about a humidity pack is exciting, which is exactly why it gets skipped. Good flower is expensive, and it quietly degrades in the jar while nobody is watching. A pack of salt water behind a membrane protects the part you actually paid for. It is the rare accessory that does one job and does it properly.
