Humidity Packs
Humidity packs hold a sealed jar, bag or tote at one steady RH. Cured plant material avoids the daily swings that change its texture and aroma. Jars take 8 gram packs at 62% and pound bins take 67 gram packs, while long-term storage runs 55% Integra Boost or 58% Boveda.

Humidity Packs
Two-Way Humidity Control: Boveda and Integra Boost Packs
Humidity packs are two-way packets that add or pull moisture until a sealed container settles at the RH printed on the pack. This collection carries Boveda and Integra Boost packs from 1 gram jar packs to 320 gram bin packs, plus CVault steel containers built around them. Comparing brands?

These packs sit under harvesting and processing supplies. Jars, bags and totes to hold them are on the storage bags and containers page. Pack size follows the plant material inside, not the size of the container.
Types of Two-Way Packs
Integra Boost Humidity Control Packs
Integra Boost uses a salt-free fill of plant-based glycerin and water. Retail packs carry an indicator card whose dot turns from pink to blue when the pack is spent. Curing packs come in 55% and 62%, with 69% to 84% for other jobs. Bulk cases run up to 3,500 packs.
Boveda Packs
Boveda packs hold a saturated salt solution behind a reverse-osmosis membrane, rated to within 2% of the label. They come in 58% and 62%, in 1, 4, 8, 67 and 320 gram sizes. The pack is its own gauge: it turns granular, then hard, when spent.
Curing Containers and Indicator Cards
CVault containers are 18/10 stainless steel with a silicone gasket, and they hold the pack in the lid. The 4 liter vault holds about half a pound and ships with a 67 gram Boveda. Integra adds quart jars with a pack basket and cards that read 10% to 60% RH.
How Growers Use Two-Way Packs
Most growers cure jars at 62% and hold long-term stock at 55% or 58%. Choose Integra for the indicator card and the small sizes, or Boveda for 58% and the salt-solution chemistry. Give a sealed container 24 to 48 hours before judging the reading. Keep it cool and dark, since a pack controls moisture only.
Frequently Asked Questions
How long do humidity packs last?
Boveda and Integra both quote two to four months in a sealed container. Opening the lid often, or packing material that is still wet, shortens that. Integra's card dot turns blue when a pack is spent. A Boveda pack is done when it feels hard all the way through.
How many humidity packs do I need?
Size by the weight of plant material, not the container. One 8 gram pack covers an ounce, a 67 gram pack covers a pound, and a 320 gram pack covers five pounds. Undersizing is the common mistake. One small pack in a large tote reads low for weeks.
How do humidity packs work?
A two-way pack releases moisture when the air in a sealed container is too dry and absorbs it when the air is too wet. Boveda does this with salt, purified water and a thickener. Integra uses salt-free glycerin and water. Both settle at the RH printed on the pack.
Can you reuse moisture packs?
No, two-way packs are replaced rather than recharged. A pack that has been dried out and re-wetted no longer holds a known setpoint. Unopened Boveda packs keep about two years in the bag, so storing spares makes more sense than reviving spent ones.
