How works a Hybrid Vaporizer.
To date you can't choose which you want. They work in tandem, and each hybrid vaporizer is built differently. Some are more convection to start, and then move over to conduction. Some are 50/50, some are 25/75, some are 75/25 ETC (rough estimates)
In a simple sense, the technical detail is that there are 2 heaters. One is the chamber itself, one is a mass underneath the chamber that cold air is pulled through.
Cold air enters the device, passes over / through the heated mass under the chamber and heats. Then the hot air passes through the chamber heating the herb.
The oven directly transfers heat to the herb.
I hope that helps!
