Boveda 2-Way Humidity Control Pack - 62% RH - 67g - Individually Wrapped - 12 Count

Steady 62% RH Storage Humidity - 67g Packs

Harvested material that sits in a container can dry out or turn damp, and checking it by hand is unreliable. This two-way pack releases moisture when the air is dry and absorbs it when the air is humid, so the container stays near 62% RH. Boveda states accuracy of +/- 2% of the RH printed on the pack in an airtight environment.

The 67g size suits large airtight jars, bags or canisters holding up to one pound (453 grams) of material. It fits growers and processors who store larger batches after harvest and want one pack per container.

Key Features & Benefits

• Two-way humidity control — adds or removes moisture automatically, with no activation step.
• 62% RH — a set humidity level for storage in dry conditions or for reviving dry material.
• Individually wrapped — each pack stays sealed until you need it.
• Up to 2 years unopened — spare packs keep on the shelf until you need them.
• Food-grade ingredients — food-grade salt, purified water and a food-grade thickening agent.

Who Should Use Boveda 2-Way Humidity Control Pack

Home growers and licensed commercial operations storing harvested material in large airtight containers will find this pack useful. It also suits anyone in a dry climate or at high altitude who needs to hold humidity steady.

Frequently Asked Questions

Q: Do I need to activate the pack?
A: No. Place it in the container and close the lid. It works automatically, releasing moisture into dry air and absorbing it from humid air.

Q: How long does one pack last?
A: In an airtight container it lasts 2 to 4 months, or less depending on the moisture of the material, how often you open the container and storage conditions. Unopened, it keeps 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 efficiency.

Q: How do I know when to replace it?
A: Do a touch test. Corners that harden or a mix of soft and hard spots mean it still works. When the whole pack feels rock solid, it is expired, so order replacements before that point.

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. A 62% RH pack aims to hold the container at that level.

Q: Does the container need to be airtight?
A: Yes. The stated accuracy applies in an airtight environment, and an airtight seal also helps the pack last longer.
