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.”
