When to Use 72% RH Boveda Packs

Boveda's two-way humidity control technology has revolutionized storage for moisture-sensitive products across multiple industries. While the 58% and 62% RH (Relative Humidity) Boveda packs are popular for cannabis storage, the 72% RH variant serves specific purposes that many users may not fully understand. This guide explores when and how to use these higher-humidity packs effectively.

Understanding Boveda 72% RH: Purpose and Function

The 72% RH Boveda pack maintains a precise 72% relative humidity environment within a sealed container. Like all Boveda products, it works through a patented two-way humidity control system that can both release and absorb moisture as needed to maintain the target humidity level. According to research on Boveda's technology, this consistent environment protects products from humidity fluctuations that can cause degradation.

Each pack contains a solution of purified water and natural salt, enclosed in a vapor-phase osmosis membrane that allows water molecules to pass through while containing the solution. This technology ensures precision without the risk of over-humidification when used correctly.

Ideal Applications for 72% RH Boveda Packs

Premium Cigar Storage

The 72% RH pack is primarily designed for premium cigar preservation. Cigar aficionados often prefer this higher humidity level to maintain proper moisture content in tobacco leaves, especially for long-term aging. Cuban cigars, in particular, are traditionally stored at slightly higher humidity levels than non-Cuban varieties.

Musical Instrument Preservation

Wooden instruments like guitars, violins, and other string instruments benefit from controlled humidity environments. The 72% RH packs help prevent wood from drying out and cracking in dry climates or during winter months when indoor heating reduces ambient humidity.

Initial Cannabis Curing

While not ideal for long-term cannabis storage, the 72% RH packs can be useful during the initial stages of the curing process. As noted in this comparison of curing versus storage, higher humidity levels can help slow the initial drying process for a more even cure.

Cannabis Considerations: When 72% RH Works (and When It Doesn't)

For cannabis, the 72% RH level is generally too high for long-term storage. Most cannabis experts recommend the 58% or 62% RH packs instead. The 72% environment can potentially increase the risk of mold growth if used for extended cannabis storage.

However, there are specific cannabis scenarios where 72% RH packs may be appropriate:

• Rehydrating overly dried flower (for short periods only)
• Initial stages of curing in very dry environments
• Temporary storage in extremely arid climates

When using 72% RH packs with cannabis, regular monitoring is essential to prevent over-humidification. As outlined in this article on moisture concerns, cannabis can become too wet if stored at high humidity levels for extended periods.

Proper Usage Techniques for Maximum Effectiveness

To get the most from 72% RH Boveda packs, follow these best practices:

Container Selection

Use airtight containers to create a sealed environment. Glass jars with rubber gaskets, humidors with good seals, or quality mylar bags are all appropriate options. The container's seal quality directly impacts the pack's effectiveness and longevity.

Sizing Guidelines

Use the appropriate size pack for your container. Boveda's sizing guide recommends one 8-gram pack for every 25 grams of stored product. For larger storage solutions, consider our professional filling equipment to help manage bulk operations efficiently.

Replacement Timing

Monitor packs for hardening, which indicates they've reached capacity and need replacement. Three key signs that it's time to replace a pack include: hardening of the pack, visible crystallization, and reduced effectiveness in maintaining humidity.

Common Mistakes When Using 72% RH Packs

Avoid these common errors when using 72% RH Boveda packs:

• Using them for long-term cannabis storage (use 58% or 62% instead)
• Placing them in containers with poor seals
• Attempting to "recharge" used packs (contrary to manufacturer recommendations)
• Underpacking containers (using too few packs for the volume)
• Mixing different RH percentage packs in the same container

These mistakes can reduce effectiveness or potentially harm stored products. For instance, using 72% RH packs for long-term cannabis storage may increase the risk of mold development, especially in larger quantities as described in this bulk storage guide.

Future Innovations in Humidity Control Technology

The humidity control market continues to evolve with new technologies and applications. Boveda leads this innovation with ongoing research into specialized RH levels for different products. Future developments may include:

• Smart humidity packs with integrated monitoring
• Sustainable and biodegradable humidity control solutions
• Product-specific formulations beyond the current RH range
• Extended-life packs for longer maintenance periods

As the cannabis and cigar industries grow, so too will the demand for precise environmental control. Research on terpene preservation shows that proper humidity control not only maintains product quality but can actually enhance the consumer experience through better flavor and aroma retention.

Understanding when to use 72% RH Boveda packs versus other humidity levels ensures you're providing optimal conditions for your specific products, whether premium cigars, wooden instruments, or cannabis in particular stages of processing.
