Size guide
Which humidity pack size fits your weed jar?
| Pack size | Flower | Container | Box |
|---|---|---|---|
| 1.5g | 1/8 oz | 1 to 2 oz jar | 10 or 20 packs |
| 4g | 1/2 oz | 5.5 to 7 oz jar | 10 or 20 packs |
| 8g | 1 oz | 8 to 10 oz jar | 10 or 20 packs |
Between sizes? Size up. A bigger pack holds the same 62%, it just has more capacity. More flower than the chart shows? Add a second pack. Filling a lot of jars this harvest? The 20-pack boxes cost less per pack.
Lab-verified, not guesswork
“Truly a game changer. No liquid salts! I tested these out with absolutely dried out flowers and within just a day or two it freshened it up.”
@citygrown, verified grower
In independent MCR Labs (Massachusetts) testing, ATMOSIScience’s two-way fiber held cannabis storage near the 60% RH target across a 30-day study, using the same salt-free, liquid-free fiber inside every Humidi-Cure pack.
Humidi-Cure® 62% is a liquid-less, salt-free humidity pack for weed jars, bags and bins. Drop it in with your cured flower and seal the lid. It holds the air inside at 62% RH, pulling moisture out when buds are too wet and giving it back when they dry out. So your stash stays soft, sticky and smells like it should.


What It Actually Does
- Absorbs moisture when it’s too humid
- Releases moisture when it’s too dry
- Helps preserve aroma, flavor, and weight
No setup. No overthinking. Just drop it in a sealed container and let it do its job.
Built for the Job
- ±2% RH accuracy
- Up to 120 days of control per pack (depending on seal and environment)
- Fiber-based tech, so no sharp edges, no corrosion, no contamination risk
- 100% biodegradable, liquid-less and salt-free design
How to use a humidity pack for weed
- Open the pack. Take it out of its outer wrapper.
- Add it to the jar. Put it in an airtight jar, bag or bin with your flower.
- Seal it tight. A good seal is what makes the pack last. Swap in a fresh one when it’s used up.
Stick to one RH level per container, and don’t mix Humidi-Cure with other humidity products in the same jar.
Humidi-Cure® vs salt-based humidity packs
Most humidity packs run on a saturated salt solution sealed in a film. Humidi-Cure does the same 2-way job at 62% with a dry plant-fiber matrix instead.
- No liquid inside. If a pack gets punctured, nothing leaks onto your flower.
- No salt. Nothing to crystallize, nothing to corrode.
- Same target. 62% RH, lab-tested.

Choosing a pack
What percentage humidity pack is best for weed?
62% for most home growers. Buds stay soft and sticky, terpenes hold, and the jar stays below the 65% where mold risk starts to climb. Prefer a crisper bud, or live somewhere humid? Some growers go a few points lower, around 58%.
Best humidity from drying to storage →What's the best humidity pack for weed?
One that works both ways and stops at 62%: it pulls moisture out of damp buds and gives it back to dry ones. Check the accuracy, and make sure nothing inside can leak. Humidi-Cure® 62% holds ±2% with dry plant fiber inside, so there's no salt solution near your flower.
The complete grower's guide to cannabis humidity →How many humidity packs do I need per jar?
One pack per jar, sized to the flower inside: 1.5g for 1/8 oz, 4g for 1/2 oz, 8g for 1 oz. Between sizes, size up. Jar packed past that? Add a second pack.
See the jar size chart ↑Are humidity packs necessary for weed?
Not for a stash you'll finish this week. For anything you keep longer, yes. A sealed jar keeps air out, but it can't fix buds that went in too wet or too dry. That's how weed ends up smelling like hay, or growing mold.
Weed smells like hay? Here's the fix →Can I make a DIY humidity pack for weed?
You can, but orange peels, damp paper towels and tortilla tricks only add water. They can't take it back out, so it's easy to overshoot and invite mold. A 2-way pack works in both directions and stops at 62%.
Is your storage causing mold? →Using it
How do you use a humidity pack for weed?
Take it out of the outer wrapper, drop it in an airtight jar, bag or bin with your flower, and seal the lid. No soaking, no setup. Stick to one RH level per container, and don't mix it with other humidity products.
How to keep weed fresh for months →Can you use humidity packs for curing weed?
Yes. Once buds are dry enough to jar (small stems snap instead of bending), add a pack sized to the jar. It holds the jar at 62%, so you're not guessing between burps.
How long to burp cannabis jars →Can a humidity pack rehydrate dry weed?
Yes, if the buds are dry but not burnt out. Seal them in a jar with a pack and give it a few days to come back toward 62%. Texture and smoothness usually return. Aroma that has already faded won't fully come back.
How to rehydrate weed the right way →Are humidity packs bad for weed?
No. A 2-way pack won't push a jar past 62%, so it can't make buds soggy, and there's no liquid inside Humidi-Cure to leak. One catch: it's not a dryer. If buds are already wet or squishy, dry them out first, then jar them with a pack.
Weed too moist? What to do →How long does a humidity pack last?
Up to 120 days. The seal decides the rest: a tight lid you rarely open stretches it, and a leaky lid or a jar you open every day shortens it. Storing longer than that? Swap in a fresh pack.

Not sure how many packs your jars need?
Enter your flower weight and jar count. The calculator picks the pack size per jar, adds up the packs and tells you which boxes to buy. Example: 3 jars with 1 oz each = three 8g packs, one 10-pack box.
