Boveda vs Integra Boost: 58 or 62%, and How Long Packs Last

Boveda and Integra Boost do the same job: a sealed pouch that releases or absorbs water vapor to hold a closed jar at one fixed humidity. Boveda's packs hold a salt solution and are now sold for cannabis under the name Vivi Fresh; Integra Boost holds glycerin and water and comes with a card that turns blue when the pack is spent. Either keeps flower inside the 55 to 65% range recommended for storage, and a pack lasts roughly two to six months in a jar you open regularly. For vaping, 62% suits convection devices and dry climates, while 58% gives a crisper grind for small conduction ovens.

We haven't tested these packs side by side; this comparison works from Boveda's, Vivi's and Integra's own documentation and store listings checked in October 2026.

Boveda for Weed Is Now Vivi Fresh

Boveda has moved its cannabis packs to a new brand called Vivi. Boveda's help center says Vivi Fresh is exactly the same as Boveda 58% and 62% in new packaging, and that Vivi is a Boveda brand, not a separate company. Boveda's own store no longer sells the herbal packs, but head shops still carry Boveda-branded stock, so both names are on shelves.

One thing did change. Vivi sells its two small sizes only at 58% and its two large sizes only at 62%, according to Vivi's help center. A small 62% pack now means Boveda-branded retail stock or Integra.

How Two-Way Humidity Packs Work

Both packs are pouches that pass water vapor but not liquid. The solution inside sits at a fixed equilibrium humidity: when the jar air is drier, water evaporates out of the pack, and when it's wetter, the pack soaks it up. Neither chemistry is new; labs hold containers at constant humidity with salt solutions and with glycerin and water, each under its own ASTM practice.

Boveda and Vivi Fresh

Boveda and Vivi Fresh packs contain purified water, natural salts and a food-grade thickener inside a vapor-permeable membrane. Boveda rates its standard formulas at plus or minus 2% RH. A new pack is soft and squishy, and small crystals inside it are normal salt crystals, not a defect.

Integra Boost

Integra Boost packs contain a blend of plant-based glycerin and water in a white kraft paper pouch, with no salt. Every pack ships with a humidity indicator card that tells you when to replace it.

Boveda vs Integra Boost at a Glance

Boveda 58 vs 62: Which Humidity Is Better for Vaping?

Four points of relative humidity is a small change, but you feel it in the grinder and the oven. At 62%, flower is slightly sticky and springy. At 58%, it's a touch crisper, grinds more evenly and packs more easily into a small chamber. Both sit inside the 0.55 to 0.65 water activity range of the ASTM D8197 storage standard, so neither is wrong.

The makers don't agree on which suits vaping. Integra describes its 62% pack as ideal for vaporizers and pitches 55% at joints. Vivi made 58% the default for its small packs. Plenty of vaporizer owners run 58% for the grind, and it matters more in a conduction oven than a convection one: when the chamber wall does the heating, crisper flower packs evenly and heats faster, while hot air copes with slightly moister flower.

Note: Never mix RH levels or brands in one jar. Vivi warns that different packs work against each other and wear each other out.

What Size Humidity Pack Do You Need?

The Integra column comes from its size chart; its FAQ is slightly more cautious and rates the 4 g pack for 12 g. The Vivi sizes are as labeled in Vivi's store.

Going bigger is fine: both makers say extra pack capacity does no harm and simply lasts longer, and that packs can touch the buds directly. Don't cut or tear them.

How Long Do Boveda Packs Last?

Vivi says a pack lasts 2 to 6 months depending on how airtight the container is and how often it's opened, and recommends replacing it every three months anyway. Integra says its packs last from a couple of months to a full year once opened. Sealed in their wrappers, both keep for two years.

Spotting a spent pack is where they differ.

• Boveda and Vivi Fresh
  A fresh pack is soft. As it gives up water it stiffens, and one that has gone hard all the way through has nothing left to give. You can't feel that without opening the jar, so go by the calendar and swap at three months.
• Integra Boost
  Drop the indicator card in the jar with the pack. The dot moves from pink to lavender to bright blue, and bright blue means replace it.

Tip: Boveda suggests writing the start date on the flat edge of each pack with a felt-tip marker. A ballpoint or sharp pencil can puncture it.

Do Boveda Packs Work?

Inside an airtight container, yes. The ASTM storage standard names salt-based humidity sachets as a way to bring under-humid flower back into range. What a pack can't do is fix a bad lid: in a jar that leaks, it is trying to humidify the room and will be spent in weeks. Our humidity management guide covers checking a jar with a hygrometer.

If flower smells weaker when you open a jar with a pack in it, Vivi says the terpenes stayed in the bud instead of escaping into the jar. That's the maker's account; we haven't seen independent data either way.

Can You Recharge a Boveda Pack?

No. Vivi says recharging throws off the calibration and can introduce mold, and Boveda adds that a rehydrated pack can form sharp salt crystals that puncture the inner membrane and leak. Integra's instructions are simply to replace the pack. At $1 to $2 for a small pack, it isn't worth risking an ounce of flower to save one.

What Boveda and Integra Boost Packs Cost

Prices as listed in October 2026.

For one jar, a $1.50 pack swapped every three months works out to 50 cents a month. Headshop.com has the Boveda 58% 8 g 10-pack and single Boveda 62% packs, and Smoke Cartel has the 58% 67 g 12-pack. Smoke Cartel also lists Integra Boost, but every Integra listing was out of stock when we checked, so for now Integra's own store is the reliable source. Vivi sells direct too; its 1 oz size was sold out.

Boveda vs Integra Boost: Which Should You Buy?

Both hold a sealed jar in range, and we haven't found independent testing showing either keeps flower fresher. Choose on features and price.

How to Rehydrate Weed

The safe way to rehydrate weed and get moisture back into it is to seal it in an airtight jar with a two-way humidity pack and wait. Vivi says 24 to 48 hours, depending on how dry the flower is.

1. Check it for mold first. Rehydrating won't rescue moldy flower.
2. Put it in an airtight jar it mostly fills.
3. Add a pack sized for the amount. Integra notes that extra or larger packs add moisture faster.
4. Close it and leave it at room temperature for 24 hours. Opening it every few hours lets the moisture out.
5. Check by feel: springy buds, stems that snap rather than bend. If it's still crispy, give it another day, then leave the pack in.

Why Not Bread, Lettuce or Orange Peel?

Fresh food is mostly water and has no off switch. Sealed in a jar, bread or lettuce pushes the humidity far above the 65% ceiling where the ASTM standard draws its mold line, and the food itself starts to rot next to your buds. Citrus peel adds its own oils and bread adds its own smell. Vivi warns against lettuce, citrus peels, soaked sponges and bowls of water too. A pack costs less than the flower you'd be gambling with.

What Rehydrating Can and Can't Fix

Water, texture and an even grind come back. Three things don't:

• Lost terpenes
  The pack adds water, not aroma. Integra sells Terpene Essentials packs that add a single terpene isolate, which is flavoring rather than a restoration.
• THC that has turned into CBN
  Oxidation doesn't reverse.
• Trichomes that broke off
  They're at the bottom of the bag. Scrape them up and treat them as kief.

What Bone-Dry Flower Does in a Vaporizer

Bone-dry flower grinds to powder that slips through screens and clogs airflow, so go coarser or give the grinder fewer turns (our guides to choosing the right grind and using a weed grinder cover both). It also heats faster, which makes the first draws hot and harsh and finishes the bowl early. Start a step lower than usual (our vaping temperature guide has the ranges) and stir conduction ovens halfway. Expect thinner vapor too, which is why moisture is on our list of ways to get bigger vapor clouds.

Frequently Asked Questions

How long do Boveda packs last?

Vivi, which now sells Boveda's cannabis packs, says two to six months depending on how airtight the jar is and how often you open it. It recommends replacing them every three months. Unopened, they keep for two years.

Is Integra Boost better than Boveda?

Neither is clearly better at holding humidity. Integra's advantages are the indicator card, a 55% option and a lower price per small pack in 20-packs; Boveda's is 58% in small sizes, which Integra doesn't make.

Can you rehydrate really dry weed?

Yes, if it isn't moldy. Seal it in an airtight jar with a two-way humidity pack for 24 to 48 hours, longer if it's still crispy. Moisture and texture come back, but the terpenes it lost while drying out don't.

Can bread rehydrate weed?

It can add moisture, but it's a bad idea. Bread pushes a sealed jar far above safe humidity, can grow mold of its own and leaves its smell on the flower. A humidity pack does the same job without those risks.

Can you still vape weed if it's dried out?

Yes. Dried-out flower is weaker on flavor and harsher, but it isn't harmful unless it has mold. Grind it a little coarser and start at a lower temperature.
