Boveda 2-Way Humidity Control Pack - 62% RH - 67g - 20 Count

Steady 62% RH Storage for Larger Containers - 67g Packs

Plant material stored in an airtight container can dry out or turn humid depending on the room around it. This 2-way humidity control pack releases moisture when the air is dry and absorbs it when the air is humid, holding the container at 62% RH. Boveda states accuracy of +/- 2% of the RH printed on the pack in an airtight environment.

The 67g size suits large jars, bags and canisters holding up to one pound (453 grams) of material. This 20 count suits growers who store several containers or larger batches after harvest and want to keep spare packs on hand.

Frequently Asked Questions

Q: How do I use the pack?
A: Remove a pack from its resealable bag and place it in your jar or bag of material. Close the container so it is airtight, and reseal the bag of spare packs. The pack works automatically.

Q: How long does a pack last?
A: In an airtight container a pack lasts 2 to 4 months. Actual life depends on moisture content, how often you open the container and storage conditions. Unopened packs last up to 2 years.

Q: Can I mix different RH levels in one container?
A: No. Mixed RH levels or other humidification products in the same container counteract each other and reduce effectiveness.

Q: How do I know when to replace a pack?
A: Do a touch test. A pack with hardening corners or some soft spots is still working. Replace it once the whole pack feels rock solid.

Q: What does RH mean?
A: RH is relative humidity, the amount of moisture in the air compared with the most it can hold. A 62% RH pack keeps the container near that level.

Q: What is in the pack?
A: Food-grade salt, purified water and a food-grade thickening agent.
