Up until now, the largest and most popular size (60 grams) has been Boveda's bread and butter for wood humidor maintenance. Typically, 3-4 packs are used to properly regulate a desktop humidor. This process has been condensed into a larger single unit with our 320 gram pouch. The pouch lasts up to 6x longer than any previous Boveda pack.

We believe this format will become the new standard for 2-way humidity control in enclosed spaces, providing growers with less maintenance than ever before. The 320 gram pouch is designed for containers of all sizes. Multiple 320g packs can be mounted in even larger containers.

Every Boveda RH is accurate to +/- 1% in an air tight environment, which humidors are not. It's common that the actual RH of your humidor will stabilize up to 5 points lower than the Boveda RH you're using, due to humidor and ambient dryness.

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