What Is a Boveda Pack?

Boveda packs are sealed packets containing a saturated salt solution that automatically regulates humidity in both directions.

The packet uses a permeable membrane that allows water vapor to pass through while keeping the salt solution safely contained inside.

This two-way system means the pack releases moisture when your container gets too dry and absorbs excess moisture when humidity rises above the target level.

Unlike traditional humidity control methods that only add moisture, Boveda packs respond automatically to your container's environment.

Originally developed for cigar storage, Boveda packs have become the standard for cannabis humidity control because they require zero monitoring or maintenance once you place them in your container.

How Boveda Packs Work

The science behind Boveda packs is simpler than it sounds. Each pack contains a saturated salt solution that naturally establishes a specific relative humidity level.

The permeable membrane surrounding this solution allows water vapor molecules to pass through based on the humidity differential between your container and the pack itself. When the air inside your container drops below the pack's target humidity, water vapor escapes from the pack to rehydrate your cannabis.

When humidity inside the container rises above the target level—perhaps from introducing freshly cured flower or opening the container in humid weather—the pack absorbs that excess moisture to bring conditions back to the target range.

This automatic regulation continues throughout the pack's lifespan without any activation, charging, or maintenance on your part.

Why Use Boveda Packs for Cannabis?

Properly cured cannabis contains 9-11% internal moisture content, and maintaining this level preserves everything that makes premium flower exceptional. When moisture levels drop too low, terpenes evaporate and cannabinoids degrade faster.

When moisture climbs too high, you risk mold growth and harsh smoke from incomplete combustion. Boveda packs maintain this balance automatically.

Your cannabis stays in the optimal range without constant checking or adjustment. This preservation protects the complex terpene profiles that give strains like Pluto and Devil's Mistress their distinctive aromas and flavors.

Extended Freshness

Cannabis stored without humidity control degrades noticeably after 4-6 weeks. With Boveda packs in airtight containers, properly stored flower maintains quality for 6-12 months.

This extended freshness means you can stock up on favorites from Mood's THCa Flower collection without worrying about waste.

Consistent Experience

Humidity-controlled storage delivers predictable effects every time you open your jar. The first session tastes and feels like the last session, even months apart.

This consistency matters whether you're preserving Kush Mintz for its distinctive flavor profile or maintaining a collection of different strains for various occasions.

Safety Benefits

Boveda packs prevent the dual threats of excessive dryness and dangerous moisture. Flower stored too dry produces harsh smoke that irritates your throat and lungs.

Flower stored too wet risks developing mold, which creates serious quality and safety issues. Two-way humidity control eliminates both problems by maintaining the optimal range automatically.

Choosing the Right Boveda Pack

Selecting the correct Boveda pack involves two decisions: humidity percentage and pack size. Both choices directly affect how well the pack preserves your cannabis.

Humidity Percentage: 58% vs. 62%

Most cannabis users should start with 62% RH packs for storage at normal room temperatures between 60-70°F. This humidity level delivers the springy texture and preserved terpenes that most people prefer.

Your flower will feel properly hydrated without being damp, and terpene profiles stay vibrant for months. Choose 58% RH if you prefer slightly drier flower, your storage space runs above 70°F, or you're planning long-term storage beyond six months.

The relationship between temperature and relative humidity means warmer air holds more moisture at the same percentage. A 62% pack that works perfectly at 65°F can over-saturate your flower when storage temperatures reach 75°F.

Temperature Adjustment Formula

Reduce your target humidity by 2-3% for every 5°F above 70°F. If your storage space typically runs at 75°F, use 58% packs instead of 62%.

This temperature-based adjustment explains why some users experience perfect results with 62% in winter but find their pre-rolls feel too soft in summer with the same packs.

Pack Sizing

Boveda manufactures different sized packs for various container volumes. The two most common sizes for cannabis storage are 4-gram and 8-gram packs.

Four-gram packs handle up to an eighth ounce (3.5 grams) of flower. These smaller packs work perfectly for Dante's Inferno or other premium strains you're sampling in smaller amounts.

Eight-gram packs regulate humidity for up to one ounce of cannabis, making them ideal for bulk storage of your favorite strains. Undersized packs work harder to maintain target humidity and deplete faster.

Container Considerations

Boveda packs only work effectively in airtight containers. Glass mason jars with proper sealing lids provide the ideal environment for humidity regulation.

Acrylic containers and metal tins with tight-fitting lids also work well, but glass remains the gold standard because it doesn't create static electricity that damages trichomes. Avoid wooden boxes and thin plastic bags—both allow moisture to escape, forcing your Boveda packs to work harder.

Leave about 25% headspace in your container. This ratio gives Boveda packs room to regulate humidity effectively without overcrowding your flower.

How to Use Boveda Packs

Setting up humidity-controlled storage takes about five minutes and requires no special tools. The process works the same whether you're storing top shelf flower or economy options.

Basic Setup

Choose your humidity percentage based on your storage temperature and texture preferences. Select the appropriate pack size for your cannabis amount.

Place the Boveda pack directly on top of your flower—the packs can safely touch cannabis because the membrane only allows water vapor through, not salts or other contents. Seal everything in your airtight glass container.

Store the container in a cool (60-70°F), dark location like an interior closet or drawer. Avoid areas near windows, heaters, or other heat sources that cause temperature fluctuations.

Verification Method

Add a basic hygrometer to your container alongside the Boveda pack for the first 24 hours. This inexpensive device measures relative humidity and confirms your setup works correctly.

After sealing everything for a full day, check the hygrometer reading. If RH matches your pack's target percentage, your container seals properly and your pack size is appropriate.

If the reading runs high, your flower likely went into storage too wet—let it air out before resealing. If the reading runs low, either your container is leaking or you need a larger pack size.

For Pre-Rolls

Pre-roll storage requires slightly different pack placement than bulk flower. Use one 62% Boveda pack per 8-10 pre-rolls, adjusting to 58% if your storage space runs warm.

Nestle the pack between your pre-rolls rather than placing it only on top or bottom—this positioning prevents moisture pooling and ensures even humidity distribution. Store pre-rolls in glass mason jars or metal containers that seal tightly.

Common Mistakes to Avoid

Even with Boveda's simple design, a few common mistakes can compromise your storage results. Avoiding these errors ensures your packs perform as designed.

Combining Humidity Control Methods

Never use Boveda packs alongside other humidification systems. Different methods compete for control, wearing out faster while delivering inconsistent results.

Recharging Depleted Packs

Some people try soaking depleted Boveda packs in water to "recharge" them. This compromises the membrane's integrity and destroys the precise regulation that makes Boveda packs effective.

Replace depleted packs rather than attempting to restore them. The small cost of new packs far outweighs the risk of ruining your cannabis with a damaged pack.

Using Leaky Containers

Boveda packs maintain accuracy in sealed containers but can run several points low in leaky ones. If your hygrometer consistently reads 5-7% below your pack's rating, your container isn't sealing properly.

Long-Term Storage in Shipping Packaging

Heat-sealed mylar pouches are designed for transit, not long-term storage. When you receive flower from Mood, transfer it to an airtight glass container with a Boveda pack within 10 minutes of opening the shipping package.

Refrigeration

Don't refrigerate cannabis stored with Boveda packs. Temperature fluctuations between your refrigerator and room temperature create condensation inside the container.

This moisture doesn't distribute evenly—it creates dangerous wet spots that promote mold while leaving other areas dry. Keep cannabis at stable room temperature for best results.

When to Replace Boveda Packs

Boveda packs don't suddenly stop working—they gradually become less effective as the salt solution inside depletes. The lifespan varies based on how often you open your container and how much work the pack needs to do to maintain target humidity.

Packs last longest in containers that stay sealed most of the time. Opening your jar once a week lets the pack regulate stable conditions for months.

Opening multiple times daily introduces fresh air with different humidity levels, forcing the pack to work harder and depleting it faster. The physical indicator for replacement is simple: when your Boveda pack becomes rigid or loses its pliability, it's depleted.

In frequently-opened containers, expect to replace packs every 2-4 months. Containers you rarely open can maintain the same pack for 6+ months.

Boveda vs. Other Humidity Control Methods

Several humidity control options exist for cannabis storage, but Boveda packs offer significant advantages over alternatives through their two-way regulation system.

Traditional One-Way Humidifiers

Humidity stones, sponges, and similar products only add moisture. They can't respond when humidity climbs too high, creating risks of over-saturation and mold growth.

These methods also require constant monitoring to prevent moisture pockets that damage flower unevenly.

DIY Solutions

Orange peels, lemon rinds, lettuce leaves, and similar organic matter can rehydrate dry cannabis temporarily. However, these methods introduce uncontrolled moisture along with potential contaminants.

They also can't absorb excess humidity, making them unsuitable for maintaining long-term storage conditions. The temporary moisture boost isn't worth the mold risk.

Boveda Packs

Boveda packs provide automatic, bidirectional humidity control with zero maintenance. Place them in your sealed container, and they handle everything else.

This hands-off approach eliminates the constant checking and adjusting required with other methods while delivering precise, stable humidity levels that preserve your cannabis for months.

Storing Your Premium Cannabis Right

Boveda packs transform cannabis storage from guesswork to reliability. The automatic two-way humidity regulation maintains your flower at perfect moisture levels whether you're preserving a special eighth or managing a larger collection of different strains.

Start with 62% RH packs for standard room-temperature storage between 60-70°F. Choose 58% if you prefer drier texture, your storage runs warm, or you're planning long-term preservation beyond six months.

The small investment in Boveda packs protects the quality of premium cannabis you're already paying for.

Whether you're storing flower from Mood's best THCa strains or keeping pre-rolls fresh for future sessions, proper humidity control extends freshness from weeks to months while maintaining the terpene profiles and cannabinoid content that make each strain distinctive.
