Boveda 2-Way Humidity Control Pack - 58% RH - 320g - Individually Wrapped

Steady 58% Humidity for Large Harvest Storage - 320g

Stored harvest loses quality when the air in the container gets too dry or too damp. This pack regulates humidity in both directions: it releases moisture when the air is dry and absorbs it when the air is humid. Inside an airtight container it holds the relative humidity printed on the pack, to within +/- 2%.

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 lbs (2.5 kg) of material. Smaller jars and bags are better served by a smaller pack.

Key Features & Benefits

• 2-way humidity control — adds or removes moisture so the container stays at one level.

• No activation — place the pack in the container and close the lid.
• Individually wrapped — each pack stays sealed until you are ready to use it.
• 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. Remove it from its wrapper, place it in the container and close the lid. It works automatically, releasing moisture in dry air and absorbing it in humid air.

Q: How much material does one pack cover?
A: One 320g pack covers up to 5 lbs (2.5 kg) of material in an airtight container. For smaller containers a smaller pack size is a better fit.

Q: How long does it last?
A: In an airtight container it lasts 2 to 4 months. Opening the container often, or storing material with a higher moisture content, can shorten that. An unopened package keeps for up to 2 years.

Q: Can I mix it with other humidity products?
A: No. Do not mix different RH levels in one container, and do not combine the pack with other humidification products. They counteract each other and reduce its effectiveness.

Q: What does 2-way humidity control mean?
A: It means the pack both adds and removes moisture. It releases moisture into dry air and absorbs it from humid air, which keeps the container near its set humidity.

Q: How do I know when to replace it?
A: Squeeze the pack. It still works if the corners are hard or it has soft spots among hard areas. Replace it when the whole pack feels rock solid.
