Optimal humidity for cannabis storage

The generally agreed-upon humidity for storing cannabis is between 58 and 63 RH (relative humidity). Boveda manufactures humidity packets similar to those found in beef jerky, though the beef jerky packets only remove humidity. Boveda packets remove/add humidity to maintain a specific level listed on the packet:

Boveda makes a variety of packets, and the number on the front is the target RH. The above packet will keep cannabis at 62 RH and can be purchased from Amazon: Boveda Medium 8 Gram Humidipak 62% – 12 Pack

Be sure to only use B62 packets, as other packets, such as B72, will leave too much humidity in the container and put your stash at risk of mold.

Anything above the 58-63 RH range will increase risk of mold/mildew. Anything below that range will dry out the buds, removing essential oils and making trichomes brittle, thus losing potency during storage, grinding, and handling.
