Integra Boost’s moisture-control solution uses technology that releases or absorbs moisture. This product will maintain the relative humidity of stored cannabis at 55% or 62% (depending on your preference and the type of cannabis) to avoid mold growth or drying. Its 2-Way Humidity Regulator controls moisture consistently and effectively inside any sealed container. Tear-resistant, biodegradable, spill-proof, 100% salt-free, and made with food-grade approved ink and non-corrosive ingredients, it has been designed not to transfer any smell to cannabis. Included is a blue-light replacement indicator to let you know when to change the pack.
