Grind, Humidity & Glass: Three Levers That Change Your Flower Experience
Dec 07, 2025
When you pick up a bag of THCA flower from thisthat, the magic isn’t just in the strain — it’s in how you treat it once it’s in your hands. From grind size to humidity and even the glass you smoke from, these little details shape how your flower tastes, burns, and feels.
Here’s how to make every mylar bag hit like it should.
1. The Grind: Finding Your Sweet Spot
How you grind your flower changes airflow, burn speed, and potency.
Too fine: Your bowl or joint clogs, airflow dies, and you lose terpenes to excess heat.
Too coarse: You waste cannabinoids and get an uneven burn.
For pipes or joints: Go for a fluffy, consistent grind — similar to loose-leaf tea.
For bowls or bongs: Slightly finer gives a smoother, fuller hit.
And remember — clean your grinder often. Sticky buildup can dull flavor, especially with terpene-rich strains like Grease Monkey or Super Silver Haze.
2. The Humidity: Keep That Mylar Working
Your mylar bag does most of the work — it’s air-tight and light-blocking to preserve terpenes. But once opened, humidity becomes the deciding factor.
Ideal humidity: 58–62% RH.
Below 55% dries out trichomes and flavor. Above 65% risks mold or terpene fade.
Add a small humidity pack once you open the bag, then reseal it tightly after each use. Avoid the fridge — cold air can shock your flower and cause trichomes to break off.
If your flower ever smells muted or feels crumbly, it’s usually not the grow — it’s humidity.
3. The Glass: How Shape Changes Smoke
Glass isn’t just an aesthetic choice. It changes how hot, smooth, or flavorful your smoke is.
- Straight pipes: Quick and direct, but harsher on the throat.
- Beaker-style bongs: Filtered and cool, letting terpenes bloom.
- Recyclers or bubblers: Best for full-flavor sessions with smooth draws.
Clean your glass often — resin buildup muddies terpenes and adds bitterness. Fresh flower deserves fresh glass.
4. Bonus: Bag Rotation = Flavor Retention
If you keep multiple bags open (say Bubba Kush, MAC #1, or Apple Jacks), rotate them weekly. Opening one bag repeatedly exposes it to oxygen and humidity changes, which dulls the taste over time. Rotate your stash and keep unused bags sealed — mylar only works when it’s airtight.
Quick FAQ
Q: Should I move my flower into jars after opening?
A: Nope — your mylar bag is already oxygen-safe and humidity stable. Just reseal properly.
Q: What if the flower feels dry?
A: Toss in a 62% humidity pack and reseal. It’ll rebound within 24 hours.
Q: Can I reuse a humidity pack?
A: Not really. Once it feels crunchy, replace it — they’re single-use by design.
Good flower deserves good habits.
Keep your grind even, your mylars sealed, and your glass clean — and you’ll taste the care that went into every harvest.
