Boveda 2-Way Humidity Control Pack - 58% RH - 8g - 300 Count

Steady 58% RH Humidity Control for Stored Harvests - 8g Packs

Dried plant material loses quality when the air in its container gets too dry or too damp. This two-way pack releases moisture when the air is dry and absorbs it when the air is humid, holding the container at 58% RH. It works automatically with no activation, and the pack is rated accurate to +/- 2% of the printed RH in an airtight environment.

The 8g size suits medium-sized airtight containers such as jars, CVaults, bags or canisters holding up to an ounce (28 grams) of material. This 300 Count unit fits growers who package many containers, such as small-batch processors and commercial operations, while the pack size itself also suits a home grower storing a single jar.

Key Features & Benefits

• Two-way humidity control — adds or removes moisture to hold 58% RH.

• Food-grade ingredients — made from food-grade salt, purified water and a food-grade thickening agent.

Frequently Asked Questions

Q: Do I need to activate the pack?
A: No. The pack works automatically once it is inside an airtight container. Remove one from the resealable bag, place it in the container, and reseal the bag afterward.

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. Unopened, it keeps for up to 2 years.

Q: How do I know when to replace it?
A: Use the touch test. A pack that is hardening at the corners or has soft spots among hard areas is still working. Replace it before it turns rock solid all the way through.

Q: Can I mix it with other humidity products or RH levels?
A: No. Different RH levels or other humidification products in one container counteract each other and reduce efficiency. Use one RH level per container.

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 58% RH pack holds the container air near that level.

Q: How accurate is it?
A: In an airtight environment, the pack is accurate to +/- 2% of the RH printed on it.
