With conduction, material is heated through direct contact with a hot surface. With convection, hot air flows through the material. Convection is considered more efficient and flavorful.
For optimal performance, we recommend light cleaning after each session and thorough cleaning with isopropyl alcohol every 1-2 weeks.
170-185C for light vapor, 185-200C for balanced effects, 200-210C for maximum extraction. Start low and work your way up.
