Boveda 2-Way Humidity Control Pack - 62% RH - 320g - Individually Wrapped

Steady 62% Humidity for Large Harvest Storage - 320g

Stored harvests dry out or turn damp when container humidity drifts. This two-way pack releases moisture into dry air and absorbs it from humid air, holding relative humidity at 62% inside an airtight container. It is accurate to within +/- 2% of the RH printed on the pack when used in an airtight space.

The 320g size is the largest in the Boveda range. It suits growers who store material in large airtight bins or totes, and it covers up to 5 lb (2.5 kg) of material per pack.

Frequently Asked Questions

Q: How do I use it?
A: Remove the plastic overwrap and place the pack in your container. Make sure the container is airtight so the pack works efficiently.

Q: How long does one 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. Unopened, it keeps for up to 2 years.

Q: How do I know when to replace it?
A: Do a touch test. If the corners are hardening or some soft spots remain, it is still working. If the whole pack feels rock solid, it is expired, so order replacements before that point.

Q: Can I mix it with other humidity products?
A: No. Do not mix different RH levels or other humidification products in the same container, because they counteract each other and reduce efficiency.

Q: What does RH mean?
A: RH is relative humidity, the amount of moisture in the air compared with the most it can hold at that temperature. The 62% pack aims to keep container air at that level.
