Keep cannabis or hemp fresh with the Size 4 Boveda. Preserve up to ½ ounce for months, and maintain those sticky, fluffy buds. Protect your cannabis from mold or overdrying by adding a Boveda pack to your jar or bag. Use this Size 4 to keep up to half an ounce fresh for months, or revive dry flower.

62% RH is for:

  • People who prefer flower that is sticky and fluffy
  • People who live in dry climates
  • People who live in high altitudes
  • Reviving dry weed

Size 4 is for:

  • Smaller airtight weed storage containers, such as jars, bags, canisters, etc.
  • Preserving up to half an ounce (14 grams) of cannabis flower



Boveda is safe to touch cannabis.

First, remove a Boveda pack from the resealable plastic bag, making sure to reseal the bag after. Then simply place the pack in your jar or bag of cannabis. Replace the jar’s lid or seal the bag to ensure it’s airtight. That’s it!

Boveda 62% RH 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.

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 counteract each other and reduce the efficiency of the Boveda.

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

Do the touch test. Order replacement packs BEFORE Boveda is totally rigid to avoid a lapse in humidity protection in your cannabis container.
Boveda is still working if you feel:

  • Hardening at its corners
  • Soft spots among some hard areas

Boveda is expired if:

  • The entire pack feels rock solid all the way through.

In an airtight environment, all Boveda are accurate to +/- 2% of the RH printed on the pack.

Food-grade salt, purified water and a food-grade thickening agent.

Size 4: 2/5.08 cm x 2/5.08 cm
