Quick answer
Most DIY humidity packs only add moisture. Orange peel, a damp paper towel, a tortilla or a lettuce leaf will soften dry buds, but none of them stops at a target humidity, and all of them can bring mold into the jar. A real two-way pack also takes moisture back out when the jar runs humid. If you DIY, treat it as a short, supervised rehydration of a few hours, never as storage.

Dry weed and no humidity pack in the house: this is when the kitchen hacks come out. Some of them do work, in the narrow sense that they put moisture back into the jar. The trouble is what else they put in, and the fact that none of them knows when to stop.
One-way vs two-way
Everything in your kitchen is a one-way source. It gives off moisture until it dries out or until the jar is far too wet. A two-way humidity pack is built around a target, 62% RH for cannabis. Below that it releases moisture, above it it absorbs. That second half is what keeps a jar out of mold territory, and no DIY method has it.
The common DIY methods, rated
| Method | What it does | Risk | Verdict |
|---|---|---|---|
| Orange or lemon peel | Adds moisture fast | Mold, and the citrus smell carries over | A few hours at most, not touching the buds |
| Damp paper towel or cotton ball | Adds moisture | Wet spots, mold if forgotten | Short use, wrapped so it cannot touch the flower |
| Tortilla or bread | Adds moisture slowly | Mold, crumbs in the jar | Skip it |
| Lettuce or fresh herb leaf | Adds moisture fast | Mold, plant smell | Skip it |
| Soaked terracotta stone | Adds moisture, reusable | Easy to overdo, no target | Workable for rehydrating, not for storage |
| Salt and water in a pouch | Holds a fixed humidity | Table salt settles near 75% RH, too wet for cannabis, and pouches leak | Not for weed |
Why a homemade salt pack misses the number
A wet salt does hold a steady humidity, which is why the idea keeps coming back. But each salt has its own number. Ordinary table salt and water settle near 75% RH, well above the 55 to 65% range used for storing dry flower. Landing on 62% takes a specific formulation, and then a wrapper that lets vapor through without letting liquid out. That is the part you are paying for in a real pack.
If you DIY anyway, follow five rules
- No contact. Keep the moisture source off the buds, in a small open container or wrapped in foil with a few holes.
- Short sessions. Check after an hour or two. Stop as soon as the buds feel springy again.
- Take it out. Never leave food or anything damp in a jar overnight or longer.
- Use a hygrometer if you have one. Stop at 62%, and never let the jar sit above 65%.
- Trust your nose. If anything smells musty or you see fuzz, throw that flower away.
What a real pack costs
About $1.40 a pack in the 20-pack, and one 8 g pack looks after an ounce jar. Against the price of the flower it is protecting, that is small, and it does both halves of the job.
Not sure which size fits your jar? One pack per ounce is the rule of thumb. The details are in how many humidity packs per ounce and which pack size for which jar.
Rehydrating dry weed with a 62% pack
A pack is slower than orange peel. Expect days, not hours. In exchange it stops at 62% by itself, adds no smell, and can stay in the jar afterward to keep the flower there. The full method is in how to rehydrate weed, and why cannabis dries out explains how to stop it happening again.
Skip the orange peel
Humidi-Cure 62% is a two-way pack with a plant-fiber core. No liquid or gel inside, nothing to leak, nothing that adds a smell.

Frequently asked questions
What can I use instead of a humidity pack for weed?
For a short rehydration, a piece of citrus peel or a damp cotton ball kept off the buds will add moisture. Neither holds a target humidity, so remove it after a few hours and do not use it for storage.
Does orange peel rehydrate weed?
Yes, quickly. It also adds a citrus smell and can bring mold into the jar, so keep it off the flower and take it out within a few hours.
Can I make a 62% humidity pack with salt?
Not with table salt. Salt and water settle near 75% RH, which is too humid for cannabis. Reaching 62% takes a specific formulation and a wrapper that does not leak.
How long can I leave a DIY humidity source in the jar?
A few hours, checking as you go. Anything damp or edible left in a sealed jar for longer is a mold risk.
