Boveda 2-Way Humidity Control Pack - 58% RH - 67g - Individually Wrapped - 12 Count

Steady 58% RH Storage Humidity for Harvested Material - 67g Packs

Harvested material loses quality when the air in its container gets too dry or too damp. This humidity control pack releases moisture when the air is dry and absorbs it when the air is humid, so the container stays near 58% RH without you adjusting anything. The packs are accurate to +/- 2% of the RH printed on the pack in an airtight environment.

The 67g size suits large airtight jars, canisters, vaults or bags holding up to one pound (454 grams) of material. This 12-count unit fits growers who store at home in larger containers and those who buy ahead to keep replacements on hand.

Frequently Asked Questions

Q: How do I use the pack?
A: Remove a pack from its resealable bag and reseal the bag. Place the pack in your jar or bag of material and close the container so it is airtight. No activation is needed.

Q: How long does a pack last?
A: In an airtight container, a pack lasts 2 to 4 months. Less time is possible depending on the material's moisture content, how often you open the container and storage conditions.

Q: How do I know when to replace it?
A: Squeeze the pack. It is still working if the corners are hardening or soft spots remain among hard areas. Replace it before it turns fully rigid, and treat a pack that feels rock solid all the way through as expired.

Q: Can I mix RH levels or use other humidifiers in the same container?
A: No. Different RH levels and other humidification products counteract each other and reduce the pack's effectiveness. Use one RH level per container.

Q: What does RH mean?
A: RH is relative humidity, the percentage of moisture the air holds compared with the maximum it can hold. This pack targets 58% RH.

Q: How much material does one pack protect?
A: One 67g pack protects up to one pound (454 grams) of material in an airtight container.
