Boveda packs and Integra Boost packs both hold curing jars at a steady relative humidity, and either one works well for home growers. The main differences are the chemistry inside, the pack sizes and price, and how each brand describes its humidity range. For most home growers the better choice is simply the one you can buy fresh, in the right size and at the humidity level you want, usually around 58 or 62 percent. This guide compares the two so you can protect the harvest you grew from your favorite seeds. It is written for adults 21 and older where home growing is legal.

Why humidity packs matter for curing

After drying, buds still hold moisture inside. Curing in airtight jars lets that moisture even out slowly. If the jar is too wet, mold can grow. If it is too dry, buds turn brittle and lose aroma. A two way humidity pack adds or absorbs moisture to hold the jar near a target level, which takes a lot of guesswork out of the cure and long term storage.

Humidity packs are not a fix for poor drying. If buds go into jars wet, a pack cannot save them. Dry first, then cure. Our guide to drying temperature and humidity covers the dry.

How Boveda packs work

According to the maker, Boveda packs use a saturated salt solution held inside a membrane. Salt and water together hold a fixed humidity level, and the pack releases or takes up water vapor to keep the air in the jar near that level. Boveda sells packs at several humidity points, with 58 and 62 percent the most common choices for cannabis. Packs come in several sizes, matched to container volume. The pack is used up when it becomes hard and stiff, which signals it has given up its water.

How Integra Boost packs work

Integra Boost packs, as described by the maker, use plant based glycerin and water (salt free), also held in a breathable pouch. They are also two way humidity packs and are commonly sold at 55 and 62 percent for cannabis. Each pack comes with a separate Humidity Indicator Card, and its dot turns bright blue when the pack is spent.

Pricing changes often, so compare current prices per pack at the size you need rather than relying on any number we could print here.

Which humidity level should you choose

• 58 percent is a common middle ground that keeps buds supple without risk of being too moist.
• 62 percent keeps buds a little softer and stickier, popular for flower that will be rolled.
• 55 percent suits growers who prefer slightly drier flower, especially in humid climates.

When in doubt, start at 58 or 62 percent. The difference between them is small compared with the difference between using a pack and not using one.

How to use humidity packs in a cure

1. Dry buds until small stems snap rather than bend, usually after 10 to 14 days at about 60 degrees and 60 percent humidity.
2. Trim and place buds loosely in airtight glass jars, about three quarters full.
3. For the first few days, open jars once or twice a day for a few minutes to release moisture. Many growers wait to add a pack until jar humidity settles near the target.
4. Add one pack sized for the jar volume.
5. Store jars in a cool, dark place.
6. Use a small jar hygrometer to confirm the level, at least for the first batch.

How long do packs last

Both brands say a pack lasts for months in a sealed jar, but life depends on how dry or wet the buds were, how often the jar is opened and the room conditions. Replace a Boveda pack when it hardens, or an Integra pack when its Humidity Indicator Card dot turns bright blue. Do not try to recharge a pack unless the maker gives instructions for it.

Common mistakes

• Using a pack to rescue wet buds. Mold can still grow. Dry properly first.
• Overloading a jar. Packed jars stay humid in the middle.
• Using the wrong size pack. A tiny pack in a big jar cannot keep up.
• Storing jars in light or heat. Light and heat degrade flower over time no matter which pack you use.
• Putting packs in the dryer stage. Humidity packs are for jars, not drying rooms.

Our take

Both brands do the same job well. Pick by availability, humidity level and the end of life signal you prefer. The bigger gains come from a slow, careful dry and good storage habits.

Grow legally and responsibly

Home cultivation is only legal in some states, and each state sets its own plant limits, locking rules and rules about whether plants can be visible from a public place. You must be 21 or older to buy seeds from Kind Seed Co, and you should grow only where your state and city allow it. Check your state rules in our guide to the legal requirements for growing weed plants in your state before you plant. Federal treatment of cannabis seeds is also changing, so read our December 11 2026 seed rule explainer before you order. Keep plants and harvested flower locked away from children, pets and visitors, and never drive after using cannabis. This article is general information about gardening.

Frequently asked questions

Is Boveda or Integra Boost better for curing cannabis?

Both are two way humidity packs that do the same job. Pick by the humidity level you want, pack size and what you can buy fresh.

What humidity level is best for cured cannabis?

Many home growers use 58 or 62 percent. 55 percent suits those who like slightly drier flower.

Can a humidity pack fix buds that are still wet?

No. Packs are for holding a level, not drying. Finish the dry before you jar the flower.

How do I know when to replace a pack?

A Boveda pack turns hard when spent. Integra Boost comes with a separate Humidity Indicator Card whose dot turns bright blue when the pack is spent. Replace the pack when that sign shows.

How many humidity packs do I need per jar?

Usually one pack sized for the jar. Each maker publishes a chart matching pack size to container volume, so check it and size up rather than down for large jars.

Can I reuse humidity packs?

Use each pack until it is spent, then replace it. Follow the maker’s instructions and avoid home recharging methods the maker does not describe.
