Herb Prep & Grind
Herb Prep & Grind is a core practical topic for the M7 XL. Build a stable baseline with fixed temperature and airflow, adjust one variable per session, and keep short notes to find a reproducible setup.
Check draw rhythm, chamber fill, and cleaning intervals in a regular routine. Most quality gains come from consistency, not from extreme settings.
- Start with one repeatable profile.
- Change only one parameter at a time.
- Track taste, vapor density, and session duration.
- Clean cooling path, screens, and seals regularly.
