How to Use Humidity Packs for Curing Weed the Right Way
Learn when to add humidity packs (after drying, not during), choose 58% vs 62% for your climate, and set up jars correctly. Boveda vs Integra compared.
Written by Lorien Strydom
January 13th, 2026
Humidity packs like Boveda or Integra Boost belong in airtight glass jars at 58-62% RH after initial open-air drying, not during. We know the confusion around timing, brand choice, and RH selection brought you here.
We'll show you exactly when to introduce packs in the drying-to-curing transition, how to choose between 58% and 62% based on your specific situation, and how to set up jars for set-and-forget storage.
We include packs with our THCa flower shipments because proper humidity control preserves quality, and we'll show you the same professional approach.

Why Humidity Packs Only Work After You Dry
Cannabis must hang dry with airflow until stems snap cleanly—not bend—removing bulk moisture over 5-10 days depending on conditions. Only then do you move to jars with humidity packs for the curing phase.
Using packs too early traps moisture in a sealed environment and invites mold. The pack can't compensate for improperly dried flower.
The snap test for stems matters more than any hygrometer reading. When stems break with an audible crack rather than bending like fresh wood, you're ready to jar.
Packs maintain balance—they don't force moisture out of wet buds. Think of them as precision regulators, not rescue devices.
Here's the concrete timeline: 5-10 days hanging with good airflow, then transfer to jars with packs for a 2-4 week minimum cure. Our two-phase storage system respects this principle by using nitrogen-sealed pouches for the first 60 days, then transitioning to jars with fresh packs.
Skip this sequencing and you'll fight mold growth no matter which brand you choose. Proper drying comes first, humidity control comes second.

Choosing Between 58% and 62% for Your Climate
The decision framework that actually helps: 62% keeps buds stickier and suits dry climates or jars opened frequently. 58% provides slightly drier storage for humid regions or long-term archives.
Temperature matters too. If your room runs above 75°F, bias toward the lower option.
Concrete examples make this clear: Arizona with daily access equals 62%, Florida storing for months equals 58%. Your local climate actually changes which RH you should choose.
Here's the temperature adjustment most guides skip: reduce 2-3% for every 5°F above 70°F. Store at 75°F? Drop to a 58% pack.
This is why "just use 62" is bad advice that ignores regional moisture differences. Relative humidity isn't absolute—it changes with temperature, and your storage conditions determine success.
Note that 72% packs exist but are for emergency rehydration only. Anything above 65% risks mold in poor airflow conditions.
Our complete humidity guide digs deeper into the temperature-RH relationship and seasonal adjustments for serious collectors.
Boveda vs Integra Boost: Lifespan, Cost, and the Aroma Debate
We'll compare the two brands readers actually buy without starting a war. Both work—they just work differently.
Boveda uses a saltwater solution and has 15% higher terpene retention research compared to no humidity control. Some users report a muted jar aroma due to the water monolayer effect, though this preserves terpenes for smoking.
The aroma debate is real: Boveda creates a microscopic water layer over trichomes that protects them from degradation. This means less smell when you open the jar but fuller flavor when you consume.
Integra Boost uses plant-based glycerin, typically lasts 4-6 months versus Boveda's 2-4, and includes a red-to-blue indicator card. It costs about 20% less at scale.
Replacement cues are straightforward: Boveda hardens and becomes crunchy when depleted, while Integra's card turns blue. Both maintain target RH reliably once equilibrated.
If you prefer immediate jar smell and don't mind slightly more frequent checks, Integra delivers. If you want published research and don't mind subtle aroma changes, Boveda's your choice.
We include packs with our flower because both brands work for preservation—which one depends on your priorities around research versus value, longevity versus precision.
How Many Grams Per Jar and When to Replace
Exact numbers: 8-gram pack for up to 1 ounce in a quart jar, 67-gram pack for up to 1 pound. Multiple packs extend lifespan without over-humidifying beyond the printed RH.
Pack size relates to container air volume, not just flower weight. A half-ounce in a quart jar needs the same 8g pack as a full ounce because the air volume stays constant.
Too many packs isn't a problem, but undersizing is. The packs will simply last longer when properly sized, not push humidity higher than their rated percentage.
Replace when Boveda feels hard and crunchy—not slightly firm, but actually rigid like a cracker. Integra's indicator changes color from red to blue, removing guesswork.
Never attempt to rehydrate used packs. The accuracy degrades and you risk ruining jars to save three dollars.
Replacement timeline: 2-4 months for Boveda, 4-6 for Integra under normal use. Frequent opening shortens this, sealed storage extends it.
If you're serious about preservation, write the installation date on your jar with a marker. This removes memory-based guessing about when you added that pack.
Rehydrating Dry Weed with Humidity Packs
We'll address the common scenario honestly: seal overly dry flower in a right-sized jar with a 62% pack for 24-48 hours to restore texture and pliability. Set realistic expectations.
This brings back physical moisture and improves mouthfeel, but evaporated terpenes don't magically return. The bud will smoke smoother but won't regain its original aroma complexity.
Dispensary flower often benefits from 12-24 hours with a pack regardless of how dry it seems. This is why we package our flower with humidity control from the start.
For faster results, briefly add a small piece of lettuce or bread, but remove within 4-6 hours to prevent oversaturation. Set a timer—forgotten produce creates moisture pockets that risk mold.
The 72% packs we mentioned earlier? This is their use case: emergency recovery of extremely degraded flower that's bone-dry and crumbly.
Even with 72%, you're salvaging your investment, not restoring original quality. Accept this reality upfront.
Setting Up Jars for Even Humidity Control
Use actual airtight containers—mason jars with rubber gaskets or CVaults, not decorative jars with loose lids. Humidity packs can't fight room air when seals fail.
Match jar size to flower amount. A quarter ounce in a quart jar leaves 85% air and slows stabilization while accelerating oxidation.
Fill jars 75-80% full for ideal air-to-flower balance. This ratio allows packs to reach equilibrium faster while limiting oxygen exposure that degrades cannabinoids.
Place packs nestled among buds, not isolated at the top where moisture pools or the bottom where it doesn't circulate. Even distribution prevents wet and dry spots.
Oversized containers make packs work harder and deplete faster. They also expose more flower to oxygen, which matters more than most realize for long-term storage.
Our jar sizing guidance provides specific container recommendations based on stash size. The right setup makes everything else easier.
Cool, Dark, and Stable: Where to Keep Your Jars
Humidity packs maintain targets best at stable room temperature—60-70°F without temperature swings. Keep jars in a closet, drawer, or cabinet away from heat sources and light.
Clear glass needs complete darkness to prevent UV degradation. Light breaks down cannabinoids and terpenes regardless of humidity control.
Higher temperatures require lower RH targets since relative humidity changes with temperature. A 62% pack at 80°F creates more moisture than the same pack at 65°F.
Avoid basements (too humid in most climates), attics (temperature swings), and anywhere near appliances that generate heat. Your water heater, furnace, and refrigerator all create localized hot zones.
The temperature-RH relationship explains why summer storage often requires dropping to 58% even if you used 62% all winter. Your air conditioner affects indoor humidity, and packs must compensate.
Room temperature stability matters more than absolute temperature within the 60-70°F range. Consistent 68°F beats fluctuating 63-73°F every time.
Common Humidity Pack Mistakes and Quick Fixes
Let's list preventable errors without condescension—these trip up everyone initially. Using packs during initial drying requires waiting for the snap test instead.
Adding packs to wet flower means finishing drying first. Undersizing packs requires using 8g minimum per ounce.
Non-airtight containers can't hold the humidity packs create. Exceeding 65% RH storage creates mold risk.
Attempting to recharge packs is false economy—spent packs have degraded membranes that won't regulate accurately. Ignoring replacement signals wastes the protection you paid for.
For the Boveda aroma concern, crack jars briefly before use or break buds to release trapped terpenes. The compounds are preserved, just temporarily sealed by that protective water layer.
Frame each mistake from a cost perspective: ruining one jar of premium THCa flower costs more than years of fresh packs. Prevention beats rescue.
The "packs steal terps" myth gets explained by the monolayer preservation effect. Terpenes aren't lost—they're protected until you break that seal through grinding or combustion.
Alternative Options: Rechargeable Pods and Specialty Bags
Briefly acknowledging alternatives for specific needs: Evergreen Pods offer 5-year reusability for sustainability-minded users. Humi-Smart includes built-in indicators.
Grove Bags and TerpLoc attempt passive humidity control through specialized materials rather than active packs. They work differently and may not suit all storage situations.
Position reusables as higher upfront cost but potential long-term value for serious collectors with large rotations. Most readers will be best served by Boveda or Integra.
We keep this section brief to avoid diluting the main guidance. If you're managing dozens of jars, rechargeable systems make sense—but start with traditional packs to learn the fundamentals.
How This Works with Mood Flower
We include humidity packs in nitrogen-flushed pouches with our THCa flower shipments because we understand preservation science. For the first 60 days, keep flower in our sealed pouch.
After that, or once you've consumed enough to create headspace, transfer to a right-sized mason jar with a fresh humidity pack. We don't sell the packs, but we recommend Boveda or Integra Boost.
They maintain the quality of what we carefully cure and ship. Our complete storage guide for customers who want to maintain dispensary-fresh quality at home covers the full system.
This two-phase system—sealed pouch then jar—respects curing science. We're not just following industry standard, we're sharing expertise that protects your investment.
The packs we include are properly sized for our packaging. When you transfer to your own jars, reassess the pack size based on your new container volume.
Keep Your Weed Fresh Without the Guesswork
You now know exactly when to introduce packs—after stems snap—which RH fits your situation based on climate and usage, how to size and replace packs, and where to store jars for best results.
This system, once set up correctly, maintains quality for months without daily intervention.
The combination of right timing, proper RH, quality packs, and stable storage removes the variables that lead to degraded or moldy flower. Follow this approach and stop worrying about your stash.
