When it comes to using a dry herb vaporizer, most beginners focus on the device—its temperature settings, portability, or battery life. But there’s a small detail that makes a huge difference: grind size.
Whether you're using cannabis, lavender, or another herb, getting the grind right is key to flavor, vapor production, and even efficiency. Let’s break down why consistency matters and how to find the best grind for your device.
Why Grind Size Matters
Grind size affects how evenly your herb heats up in the chamber. Too coarse, and heat doesn’t distribute well—resulting in weak vapor. Too fine, and airflow gets restricted, possibly causing harsh hits or clogging.
A proper grind ensures:
- Even heating
- Better airflow
- More efficient herb use
- Improved flavor and vapor density
Types of Grinds and Their Effects
1. Coarse Grind
Looks like small chunks or leafy bits. Best for convection vaporizers (which rely on hot air to heat the herb).
Pros: Good airflow, doesn’t clog screens
Cons: May require higher temps or longer sessions to fully extract
2. Medium Grind (Most Recommended)
Fluffy and balanced, like dried oregano. Works well with most vaporizers, especially hybrids.
Pros: Great balance between airflow and heat contact
Cons: Might need stirring during long sessions
3. Fine Grind
Almost powdery, like sand. Ideal for conduction vaporizers that heat through direct contact.
Pros: Fast, dense vapor production
Cons: Can clog screens and restrict airflow if packed too tightly
Tips for Getting the Perfect Grind
Use a Quality Grinder
A 3- or 4-piece herb grinder gives the most even consistency. Avoid scissors or coffee grinders—they’re messy and inconsistent.
Know Your Vape
- Convection = use a looser, coarser grind
- Conduction = go finer and pack more firmly
- Hybrid = medium grind works best
Don’t Over-Pack
Even with a perfect grind, airflow matters. Pack the chamber lightly so air can move easily through the herb.
Stir Mid-Session
Especially if you’re using medium or coarse grinds. A quick stir helps expose fresh surfaces to heat and improves consistency.
Bottom Line
Your grind size can make or break your vaping experience. The right consistency helps you enjoy better flavor, smoother vapor, and more efficient use of your herb.
Pro tip: When in doubt, go for a medium grind—it’s the most versatile and vape-friendly choice.
