Here's what we actually do when setting up a CBD vaporizer for a commute:

1. Start half-closed. That's the baseline for flavor.
2. Take a test draw at home. If it feels too tight, open a quarter turn. Too airy? Close a quarter.
3. Adjust for your commute length. Short ride? Slightly tighter for a quick hit. Longer walk? Loosen up for a relaxed pace.
4. Don't chase clouds. Flavor over volume, every time.
5. Recheck after a week. Coils change as they break in, so your ideal setting might shift.

That's it. Five steps, no guesswork.
