How Vaporization Works: Conduction vs Convection Explained
Share
Vaporization heats dry herb below combustion so aromatic compounds become inhalable vapor. Conduction does that through contact with hot surfaces; convection does it with hot air moving through the load. Most modern devices blend both. Understanding the difference helps you pack, draw, and pick accessories that protect terpene timing.
Conduction
- Heat from walls/floor touching the material
- Can start flavourful quickly
- More scorch risk if packed as a dense brick against the heater
- Spacers and even packs help on glass-stem conduction-leaning ovens
Convection
- Heated air passes through the load
- Often more even when airflow is steady
- Technique-sensitive — weak draws under-extract
Hybrids in real life
Many portables mix contact and airflow. Arizer glass-stem devices, S&B cooling-unit devices, and on-demand tips each bias differently. Cooler paths — XL stems, short glass, bead stems — help you run honest temps on any bias.
Practical takeaways
- Conduction-leaning → respect heater gap and pack edges.
- Convection-leaning → steady airflow and clean screens.
- Judge by even colour and terpene clarity, not brand slogans.
Bottom line
Conduction vs convection is how heat arrives. Pack and path decide whether that heat becomes flavourful vapor or toast — learn the bias of your device, then accessorize accordingly.
Practical takeaway
Match the accessory to the friction you actually feel: hot vapor, tight draw, messy oven, or dull flavor. Keep one spare of the part that fails first. Clean on condition. Step temperature instead of jumping to maximum. Those habits protect terpene character and comfortable potency better than a drawer of unused glass.

Care that keeps the upgrade honest
Soak glass in isopropyl when film appears, rinse, and dry fully before heat. Replace screens on condition. Store stems dry and protected. Never chase flavor with a dirty path — residue flattens strain character faster than any stem length can fix.
