Convection

Convection vaporization heats cannabis flower or extracts through indirect heat, as opposed to conduction, which heats through direct heat, and which most cannabis vaporizers use. These processes are analogous to a convection oven in your home, which heats air, which in turn cooks food (convection), and a pan on a stovetop (conduction). Since convection does not involve flower or concentrate touching the heat source, there is a much lower risk of combustion occurring, whereas combustion or charring often occurs in conduction vaporizers. 

“When I vape, I prefer convection vaporizers because I know I won’t accidentally burn the flower.”
