When it comes to the world of vaping cannabis, there are really only two methods to understand, conduction and convection. Today, we will quickly explain what thees two methods are and the pros and cons of each method.
The definition of conduction is the transfer of heat through a solid object. This is the most traditional way of vaping cannabis. The conduction process in vaping is quite simple. There is a single heat source, usually a heat plate, that is in direct contact with the cannabis. This plate heats up and applies that heat directly to the cannabis in order to vaporize it. Pros of this method are faster warm up times, and cheaper devices since devices using conduction are easier to make. Cons of this method include a higher chance of combustion, minimal temperature control, and the requirement to shake around the herb in between draws.
Convection is the transfer of heat through a liquid or gas opposed to conduction, which's through a solid object. Similarly in vapes, rather than having the cannabis directly in contact with the heat source, the convection method transfers the heat through the air which vaporizes the cannabis without being in direct contact with it. Pros to the convection method include a smaller chance of combustion, more even heating, and steadier temperature control. A major con of the convection method is the longer warm up times versus conduction method. However, the biggest con may be the price. Vaporizers that use convection are generally regarded as having a higher quality and are harder to make, therefore, they are typically more expensive. If you have the budget for good quality though, this would be the way to go.
Overall, both methods are effective and hold their own set of pros and cons. While vaporizers using the convection method are more expensive, this doesn't mean there are not high quality devices that use conduction.
