Boveda 62% Size 8 protects your flower with the original terpene shield. Boveda 62% 9 Gram is precise humidity control for cannabis, which restores and maintains humidity to create a protective monolayer of water molecules over trichomes, so you can Save the Terps. Choose Size 8 Boveda for small jars and small bags. Within an enclosed container, Boveda monitors the ambient RH (relative humidity) and adds or removes moisture to maintain the specific RH engineered into the pack. Because it's impossible for Boveda to humidify beyond the RH on the pack, it's impossible to use "too much". The life of any Boveda depends how hard it has to work giving up moisture. When there are very few soft spots left in the Boveda, it's time for a replacement. 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.
