Boveda 2-Way Humidity Control Pack - 58% RH - 67g - Individually Wrapped - 100 Count

Steady 58% Humidity for Stored Harvests - 67g Packs

Stored material dries out or turns damp when humidity in the container drifts. These packs release moisture when the air is dry and absorb it when the air is humid, holding the container at 58% RH. They work automatically with no activation, and you simply place a pack in the container and close it.

The 67g size suits large airtight containers or bags, and each pack covers up to one pound (454 grams) of material. The 100 count, individually wrapped format suits growers who process regular batches or store in volume. Home growers with several large jars can use it too.

About Boveda 2-Way Humidity Control

Frequently Asked Questions

Q: Do I need to activate the pack?
A: No. It works automatically once it is in the container. Place it with your material and seal the container.

Q: How long does a pack last?
A: In an airtight container it lasts 2 to 4 months, or less depending on moisture content, how often you open the container and storage conditions. An unopened package lasts up to 2 years.

Q: How do I know when to replace it?
A: Do the touch test. Replace the pack before it turns fully rigid. Hardened corners or soft spots mean it is still working, while a rock solid pack is expired.

Q: Can I mix RH levels or use other humidifiers?
A: No. Different RH levels or other humidification products in one container counteract each other and reduce efficiency.

Q: What does 2-way mean?
A: It means the pack releases moisture into dry air and absorbs moisture from humid air. This holds the container near one RH level.

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