- Drying is about even moisture release. Fast outside + wet inside is the classic failure.
- Keep airflow gentle and indirect. Avoid heat spikes and big RH swings.
- Jar only when moisture is stable. If the jar acts “alive,” you jarred early.
You’re not trying to “dry it fast.” You’re trying to dry it even.
The 60-second setup (the vibe)
Your dry should feel boring. No heat spikes. No humidity rollercoaster. No hurricane fan. Slow, steady moisture release is the entire game — because the moment you dry the outside faster than the inside, you create a “wet core” problem that shows up later as harshness and jar drama.
What you want
- Cool-ish temps (avoid warm room heat)
- Moderate humidity (not desert dry, not swampy)
- Gentle circulation (indirect, not pointed at buds)
- Air exchange (stale air out, fresh air in)
- Darkness
What you don’t want
- Fans blasting buds directly (uneven dry)
- Hot rooms (fast outside dry, wet inside)
- Wild swings (temp/RH rollercoaster)
- “The jar is my drying room” thinking
“If the outside feels done in 48 hours, the inside is about to embarrass you.”
The quick decision engine (bookmark this)
Most drying guides give numbers. This gives you actions. Use it like a checklist when something feels “off.”
Jar RH jumps and stays high
You jarred early. You trapped moisture. That’s why the smell starts acting weird and the jar feels “alive.”
- Action: pull buds out for more air time.
- Goal: return to stability before calling it curing.
Outside feels dry inside feels spongey
Fast outside dry + wet core. The jar exposes it every time.
- Action: reduce aggressive airflow / heat.
- Goal: even dry, not fast dry.
Smell changes every single day
Moisture is still moving. You’re not stable yet — you’re still drying (even if it’s inside the jar).
- Action: stabilize first. Don’t “pack-hop.”
Sour / ammonia note
Too much moisture is trapped. Don’t negotiate with it.
- Action: pull out immediately, re-stabilize, then re-jar.
Stop swinging = stop big temp/RH spikes and dips all day. When your room bounces, buds dry uneven: crispy outside, wet inside. That’s where harshness is born.
VGrow controls (use the tech without getting nerd-trapped)
Your safest baseline for beginners (and honestly most people) is simple: run both fans in manual at a low, steady setting — because drying hates surprises. In NYC, swings are common, so triggers can be useful as guardrails, not as a constant “DJ” effect.
Best beginner baseline (no-drama)
- Manual mode for both fans
- Level 1 to start (gentle + consistent)
- Adjust one notch at a time only if needed
If you’re not sure, don’t “get fancy.” Boring wins.
When triggers help (NYC reality)
- Your room humidity spikes at night / after showers / weather shifts
- You’re running a humidifier nearby in winter
- You want the system to “catch” extremes while you’re not watching
Use triggers to prevent extremes — not to constantly chase perfect numbers.
Use triggers like guardrails (not like a DJ)
- Temperature ceiling: prevents fast outside-dry.
- Humidity ceiling: prevents trapped moisture and funk-risk.
- Advanced controls: optional — only if you already understand your room behavior.
If you ever feel the system is “fighting itself” all day, you went too aggressive. Back it off.
Drying mistakes that curing cannot fix
Curing is not a magic eraser. If you dry too fast, you can lock in problems that show up as harsh smoke, unstable jar humidity, and the “why does this smell different every day?” spiral.
“Fast dry = clean outside, messy inside. The jar exposes the lie.”
The biggest mistake: drying too fast
Heat and aggressive airflow dry the outside first, while the inside holds moisture. Then you jar it, and the jar becomes a humidity trap.
How pros define “done” (without arguing days)
Pros don’t debate “7 days vs 14 days.” They care about stability. If your flower keeps changing in the jar — smell, feel, humidity — you’re not done yet.
“Drying ends when the flower becomes stable — not when your calendar hits a number.”
The jar handoff (the moment that decides everything)
Jar only when the outside is dry and the inside isn’t hiding a wet core. If you miss this moment, you end up “curing” a problem you created.
✅ Ready to jar when
- Buds feel dry outside (not wet/sticky)
- Smell is clean/planty (not sour/funky)
- No “spongey core” feeling
❌ You jarred too early if
- Jar humidity jumps and stays high
- Smell turns “cut grass” and won’t leave
- Outside is crisp but inside feels damp
“If your jar smells like lawn clippings, you jarred too early.”
Why jars smell different on day 1 vs day 7
Day 1 is the jar revealing what you trapped. Day 7 is the jar telling you whether things stabilized. If the smell is improving and getting more consistent, your dry/handoff was clean.
- Smell keeps changing daily = moisture is still moving (not stable yet).
- Smell gets more consistent = you’re settling into a real cure.
- Smell gets worse (sour/ammonia) = too much moisture trapped; correct course immediately.
FAQ (questions people actually have)
In-page answers. No extra pages. Just clarity.
What does “stop swinging” actually mean?
It means stop big temperature/RH spikes and dips all day. Swings create uneven drying: crisp outside, wet inside.
If your environment is boring, the outcome is loud.
Is it better to dry “fast” to save terpenes?
No. “Fast” usually means you dried the outside first and trapped moisture inside. That’s harshness + jar drama.
Even is the real goal.
Why does my jar smell different day 1 vs day 7?
Day 1 reveals what you trapped. Day 7 reveals whether you stabilized.
If it’s improving and getting consistent, you’re on track. If it’s getting worse, you trapped too much moisture.
Should I point a fan directly at the buds?
Don’t. Direct airflow dries unevenly and creates that “dry outside, wet inside” trap.
Use gentle circulation in the space, not a blast on the flower.
Do I need a moisture meter?
Nice-to-have, not required. Most beginners win just by controlling swings and timing the jar handoff properly.
If you add tools, add them to confirm what your nose and feel already told you.
Once the dry is stable, curing becomes a timing decision: 62% finishes, 58% locks.
If your glass gets nasty fast and your flower burns harsh/dark, it’s usually post-harvest handling. Start with drying, then use curing packs correctly.

FAQ
What’s the biggest drying mistake?
Drying too fast at the surface (heat/direct airflow). It creates a wet core that causes jar problems later.
Can curing fix a bad dry?
Not really. Curing stabilizes a correct dry. A bad dry bakes in harshness.
How do I know I jarred too early?
Jar RH jumps and stays high, smell changes daily, or buds feel spongey inside.
Do I need a fancy drying tent?
Not if you can keep a stable, gentle environment. Stability beats complexity.
