Humidity control for storage and preservation FAQs

A true two-way humidity control pack actively maintains ideal conditions by absorbing or releasing moisture, unlike basic desiccants that only absorb. These stabilize your storage environment at exactly 62% RH, helping you avoid both drying and spoilage.

These are perfect for herbs, dried fruits, teas, spices, leaf wraps, cigars, or any item that needs stable moisture. Gardeners love them for post-harvest freshness. Cooks and collectors love that flavor and texture stay consistent.

Most of our customer report 2–3 months of reliable control per pack, depending on container tightness and climate. You’ll know it’s done when it becomes stiff or when your hygrometer shows a dip below 62% RH.

Absolutely. Each packet is made with natural, non-toxic, food-grade materials. They’re scent-free, won’t alter aroma or flavor, and are safe around herbs, spices, and pantry goods.

You should keep your unused humidity control packets sealed in their original resealable foil bag. That protects their moisture content and keeps them shelf-stable for up to 2 years. Reseal tightly after each use.

Yes, glass jars, wooden humidors, and plastic bins all work with these humidity packs, as long as they seal well. The key is maintaining a closed environment so the pack can regulate effectively.

Spend less time monitoring, and more time enjoying your harvest.

Humboldts Secret is trusted by over one hundred thousand gardeners, makers, and preservation pros. Our humidity control packs make storage simple, safe, and reliable, so you can maintain quality — without stress. Seal it, store it, and let the packs work their protective magic..
