Convection, Conduction and Combustion: The Three C’s of Buying Portable Vaporizers

Vaporizers have rapidly grown in popularity recently and while it’s good news that there is such a choice now available to consumers the issue is that with such a wide array of options and models to choose from, deciding which one is best for you is hard to do.

Here is a buying guide to help you work your way through the minefield of options and features so that you end up with the right portable vaporizer for your needs.

There is a look at why temperature control is so important, why the combustion method is not a great idea, plus an overview of the pros and cons of conduction and convection vaporizers.

Getting the right temperature

It is generally considered that vaporization is one of the healthiest ways for you to consume cannabis and this is because the vaporizer heats the herb to the optimum temperature in order to release the resin in steam form, without filling your lungs with hot ash in the process.

Achieving the right temperature with your vaporizer is essential to the success of this process which is why reliability and performance are essential when it comes to temperature control with the portable vaporizer you choose.

It pays to remember that different cannabis compounds have varied boiling points and without the specific amount of heat they need you won’t be able to successfully transform the material from a solid into a gas.

Be aware that not all vaporizers offer the feature of adjustable temperature controls. Without that feature, you might encounter problems using various products so if you like to vary what you consume and want to be able to vaporize each product successfully, look for a vaporizer that gives you the option of varying the temperature.

Avoid the combustion option

There are a plethora of portable vaporizers available and one option available utilizes the combustion method.

You can find some vaporizer pens around that use combustion, which is achieved when the herb comes into direct contact with a hot coil causing it to combust. It might sound like a more advanced technique that could enhance your smoking experience but combustion is really no different to using a hot flame.

Producing smoke instead of vapor is not going to create any additional health benefits over the traditional method of smoking in the traditional way. Avoid vaporizers that work on combustion as they are not bringing any discernible advantages or health benefits.

Conduction or convection?

Having established that combustion is not a technique to go for with your vaporizer you will be looking at products that offer conduction or convection methods.

Conduction involves placing the herb on a glass screen directly above a coil or heating element which then raises the temperature to the optimum level of between 350°F – 450°F. The glass screen is designed to make sure that the herb doesn’t overheat and end up combusting.

The average vaporizer should take no more than about 25 seconds to reach the right temperature and produce a vapor.

A potential negative for the conduction method is the fact that the herb is always being heated which means that you could suffer unnecessary waste. You might find that you have to stir the herb regularly to get even heat distribution, although it should also be said that the quality of vapor produced can also be influenced by how well you grind and pack the herb.

The popular alternative to this method is convection.

Convection involves heating the herb by drawing hot air through your vaporizer, using a mesh screen which you place the herb on so that the product doesn’t come into direct contact with the coil being used to generate the heat.

The obvious advantage to this method is because the herb is heated by hot air, wastage is minimum which is not something you can always say with conduction.

Both conduction and convection vaporizers take an almost identical amount of time to reach their optimum temperature and deliver the product so there is no real time advantage between the two options.

It is probably fair to say that convection vaporizers have to be considered superior to conduction simply because you don’t experience any wastage, although that fact is often reflected in their price tag, and they tend to be bulkier too, so that might be a consideration.
