Quick Answer
Dry hits usually happen when oil flow cannot keep up with heat demand, especially with thick CBD oils.
Technology
Thick oil causes dry hits when the heating area is not replenished quickly enough during use.
- Dry hits are often flow-related.
- Power, intake, and oil viscosity interact.
- Testing should include repeated-use patterns.
Root cause
The heating zone can run short of oil when viscosity, intake design, or power settings are mismatched.
