Protects Up to 5 Pounds Flower

Boveda Size 320


Relative Humidity (RH) Level for Cannabis

Sold out

The Size 320 is the largest Boveda and is often used in storage bins to protect up to 5 pounds of cannabis. The original terpene shield, Boveda is precise humidity control for herbal medicine, which restores and maintains humidity to create a protective monolayer of water molecules over trichomes, so you can save the terps. Experience for yourself how much better hemp is with Boveda. Boveda Size 320 is sold individually.


Restore and protect your terpenes with the the orginal terpene shield. Place Boveda in packaging and/or storage for precise Relative Humidity (RH) to protect all the good stuff (terpenes, cannabinoids and flavonoids).

Choose 58% or 62% RH—a personal preference depending on how you prefer your experience or on what the humidity level is where you are. Some prefer 58% RH for personal-use products or 62% for larger storage

All-natural salts and pure water inside keep flower fresh for 2-4 months in airtight containers. Just place in container with up to 1 oz (30 g) of hemp flower. Replace when Boveda is rigid.

Preserves the "smell" that's released after the grind. Boveda creates a monolayer of purified water molecules that naturally coats trichomes to shield terpenes and cannabinoids preserving the smell until use.


Single pack individually wrapped in factory sealed in a high-barrier plastic. Unopened, Boveda can stay fresh for up to 2 years.

Do not mix Boveda RH levels within the same container, and do not use Boveda in the same container with other humidification products. They will fight against each other and reduce the efficiency of the Boveda.
