How to Cure Weed: The Simple, Repeatable Method

Curing is what turns a decent harvest into smooth, great-tasting flower. Drying gets buds safe to store; curing finishes the job so the smoke is velvet and the aroma pops. Follow this straightforward process once and you can repeat it every harvest.

Drying vs. curing (why both matter)

• Drying: 7–14 days in the dark with gentle airflow. Goal is to remove surface moisture so buds don’t mold.

• Curing: 2–8 weeks in airtight jars. Moisture equalizes from the center out, chlorophyll breaks down, terpenes bloom, and the burn turns clean.

Skip curing and you’ll still have weed—just not the smooth, flavorful kind you were growing for.

Tools you actually need

• Clean glass jars with airtight lids (a few small, a few large)

• Two-way humidity packs (58% or 62%)

• Hygrometer for at least one jar

• Cool, dark shelf: 15–21 °C (60–70 °F)

• Tape and marker for strain and date

Step-by-step: how to cure weed in a jar

1) Make sure the dry is finished

• Small stems should snap, not bend.

• Buds feel dry outside but not crumbly.

• If stems are rubbery, keep drying.

2) Trim

Dry trim for maximum trichome protection in drier climates; wet trim if humidity is high. Either way, trim over a clean tray and wear gloves.

3) Jar it

Fill each jar 70–80% full so there’s some air space but not a huge pocket of oxygen. Add a 58% or 62% pack and seal.

4) Burp on a taper

• Week 1: Open once or twice daily for 5–10 minutes. If jar RH stays over 65–70% an hour after closing, spread buds on parchment for 30–60 minutes, then re-jar.

• Week 2: Open every other day.

• Weeks 3–4: Open twice a week.

• After: Once a week, or not at all if jars are only for storage.

5) When is it “done”?

Two weeks is the minimum for a smoother burn. Four to six weeks is the sweet spot for most strains. Heavier dessert/gas profiles love six to eight weeks.

Quick fixes for common issues

• Too wet: RH won’t drop below 65% → remove packs, air buds briefly, re-jar.

• Too dry: RH sits near 52–55% → add a fresh 62% pack for 24–48 hours, then switch to 58%.

• Grass/hay smell: You dried too fast or are curing too wet. Hold 58–62% and give it more time—most of the “green” note fades in a couple of weeks.

• Musty or fuzzy growth: Mold. Don’t salvage—discard, sanitize, and tighten up your dry next run.

Drying that sets you up for a great cure

• Hang whole branches in a dark room at 55–60% RH, 15–21 °C.

• Move room air gently; never blast buds directly.

• Expect 7–14 days until small stems snap.

• In very dry places, leave more leaf on. In very humid places, lightly defoliate mid-dry for airflow.

Flavor targets by style

• Bright/citrus/pine sativas: Cure 4–6 weeks at 58% for a snappy, clean finish.

• Dessert or gassy indicas/hybrids: Cure 6–8 weeks at 62% early on for creamy mouthfeel, then store at 58%.

• Balanced hybrids: Most land perfectly at 4–6 weeks, 58–62% RH.

Storage habits that keep jars great for months

• Keep a small “daily” jar and leave your best colas sealed.

• Store cool and dark. Sunlight and heat flatten terpenes fast.

• Consolidate into smaller jars as you smoke through a batch to reduce air space.

One-page workflow (save it)

1. Dry 7–14 days (55–60% RH, 15–21 °C, dark).

2. Trim, jar 70–80% full, add 58–62% pack.

3. Burp daily in week 1, taper in weeks 2–4.

4. Cure 4–6+ weeks at 58–62% RH.

5. Store cool, dark, minimal headspace; use a separate daily jar.
