Best Humidity Pack for Cannabis: Boveda 62%

Boveda 62% is the pick for cannabis storage. It is a two-way pack. It adds moisture to dry flower and pulls moisture from wet flower. The 8 g size fits a jar with up to 1 oz (28 g).

Why Boveda 62% Wins

Boveda uses a saturated salt solution inside a membrane. The pack holds a target RH and reacts to the air in the jar. A jar at 62% RH keeps water activity near the range in ASTM D8197, 0.55 to 0.65. That range limits mold risk and slows terpene loss. Boveda packs have no indicator card. Check the pack: it turns stiff and grainy when spent. Replace it when that happens.

Runner-Up: Integra Boost 62%

Integra Boost 62% is the other two-way pack sold for cannabis. Integra describes its packs as a glycerin-based solution. Integra sells 55%, 62%, 69%, 72%, 75%, and 84% RH packs. The 8 g pack fits up to 1 oz. The 67 g pack fits up to 1 lb. The 320 g pack fits larger totes. Each pack ships with a humidity indicator card. The card changes color when RH drops. That card is the main edge over Boveda.

Pick the RH First

RH matters more than brand. A 62% pack suits curing and long storage. A 58% pack suits flower that will be ground and smoked. Above 65% RH raises mold risk. Below 55% RH terpenes leave the flower faster. Do not mix 58% and 62% packs in one jar. Pick one target and hold it.

Bottom Line

Buy Boveda 62% in 8 g packs for small jars and 67 g packs for ounce jars. Buy Integra Boost 62% if you want the indicator card. Both packs are two-way. Both need a sealed container. Replace spent packs. A pack that crunches or feels dry no longer holds RH.
