Keep cannabis or hemp fresh with the Size 4 Boveda. Preserve up to 1/2 oz, and keep your buds fluffy and sticky. It can safely touch your flower and protects against overdrying and mold.

Boveda works automatically; you do not need to activate the pack. If the environment in the container is dry, it will release moisture. If it is humid, the pack will absorb moisture.

62% RH is for:

  • People who prefer sticky, fluffy flower
  • People who live in dry climates
  • People who live in high altitudes
  • Reviving dry cannabis

Size 4 is for:

  • Small airtight weed storage containers, including jars and bags
  • Preserving up to half an ounce (14 grams) of cannabis flower


Boveda is safe to touch cannabis.

Place the pack in your jar or bag of cannabis. Replace the jar’s lid or seal the bag to ensure it’s airtight. Store remaining Boveda packets in airtight container.

Do not mix Boveda RH levels within the same container.

Do not use Boveda in the same container with other humidification products as they will counteract each other and reduce efficiency.


In an airtight container: 2 to 4 months (or less depending on the moisture content of the flower, how frequently the container is opened, and the storage conditions)

Unopened package: up to 2 years

Boveda is still working if you feel hardening at its corners or soft spots among some hard areas

Boveda is expired if the entire pack feels rock solid all the way through
