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

Steady 58% RH Storage Humidity for Harvested Plant Material - 8g Packs

Harvested plant material loses quality when stored air runs too dry or too damp. Boveda 2-way packs release moisture when the container is dry and absorb it when the container is humid, holding the air near 58% RH. In an airtight container, accuracy is +/- 2% of the RH printed on the pack.

The 8g size covers up to one ounce (28 grams) of material, which suits medium-sized airtight jars, bags and canisters. This bulk unit holds 300 individually wrapped packs, so it fits growers and processors who package or store material in volume and want a ready supply for replacements.

Key Features & Benefits

• Two-way humidity control — adds or removes moisture automatically, with no activation needed.
• 58% RH level — suits storage in more humid climates and material that breaks down more easily.
• Individually wrapped packs — each pack stays sealed until you use it, with up to 2 years of unopened shelf life.
• Simple to use — drop one pack into the container and close the lid or bag.
• Food-grade ingredients — food-grade salt, purified water and a food-grade thickening agent.

Who Should Use Boveda 58% RH 8g Packs

Commercial growers, processors and packagers who store or ship harvested material in medium-sized airtight containers will get the most from this 300-count unit. Home growers with several jars can use it too, as long as they can use or store the quantity.

Frequently Asked Questions

Q: How long does one pack last?
A: In an airtight container, a pack lasts 2 to 4 months. Moisture content of the material, how often you open the container and storage conditions can shorten that. Unopened packs keep for up to 2 years.

Q: How much material does one 8g pack cover?
A: One pack covers up to one ounce (28 grams) of material. Use more packs for larger containers or quantities.

Q: Do I need to activate the pack?
A: No. It works automatically once sealed in an airtight container with your material. If the air is dry it releases moisture, and if the air is humid it absorbs moisture.

Q: Can I mix different RH levels or other humidifiers in one container?
A: No. Different RH levels and other humidification products work against each other and reduce efficiency. Use a single RH level in each container.

Q: How do I know when to replace a pack?
A: Do a touch test. A pack with hardening corners or soft spots among hard areas still works. Replace it before it turns rigid all the way through, to avoid a gap in humidity protection.

Q: Is it safe to touch my material?
A: Yes. The pack is made to sit in direct contact with your material in the container.
