Beginner’s Guide To Sub Ohm Vaping

What Is A Sub Ohm?

In short, Sub Ohm vaping means the heating coil has a resistance value of less than 1.0 ohms. ‘Sub’ simply means ‘below’ in Greek, so it can be considered ‘below’ one ohm.

A low resistance coil such as a Sub Ohm allows for a higher amount of current and more electrical energy to reach the coil quicker, and this means the coil will heat up at a faster rate, and will reach a higher temperature. A hotter coil will allow for a larger amount of eliquid to be vaporized at one time, and when combined with an open airflow, will increase both flavour and vapour production.

Sub Ohming with Nicotine and Eliquid

Due to the increase in temperature when using a Sub Ohm coil, a larger quantity of vapour is produced than with a coil rated above 1.0 ohm. Within this larger quantity of vapour will be a higher percentage of nicotine, as more has been vapourised due to the increase in heat. As such, we don’t recommend using a strength higher than 6mg, as higher strengths tend to taste harsh under these conditions for the vast majority of vapers.

Vapers who Sub Ohm also have a tendency to use eliquids high in VG, as it has almost no throat hit on its own, and also produces larger and denser clouds. Heating eLiquid at higher temperatures allows for these bigger clouds and flavour, but one of the downsides is that you’ll also be vapourising more of your ejuice at a higher rate, meaning you’ll be refilling your tank sooner than you may be used to.

Mouth to Lung VS Direct to Lung

If you’re just starting, or are already on your vaping journey, it’s fair to assume that you’ve been a regular smoker for a period of time. Traditional tobacco cigarettes are consumed by first drawing smoke into the mouth, and then inhaling into the lung; a two-stage process that’s referred to as Mouth-To-Lung.

While this method is also applicable to vaping, the Sub Ohm method requires a slightly different approach, and is referred to as Direct-To-Lung. This method requires the user to inhale straight into the lungs, bypassing the mouth stage, and is similar to using a shisha pipe.

Is Sub Ohm Better?

In short, yes and no. It depends what you’re looking to get out of your vaping experience. Both high and low resistance coils offer a different vaping experience, and each have different benefits and drawbacks. A lot of vapers have been quite happy and continue to use regular coils (between 1.0 – 2.0 ohms), and devices such as Aspire’s Nautilus tank have stood the test of time and remained exceptionally well-regarded among the vaping community.

Generally speaking, Sub Ohming is suitable for more experienced vapers looking to push the boundaries of flavours and vapour, whereas mouth-to-lung vaping is better suited to beginners and those looking for just a simple way to consume nicotine without smoking tobacco.

Sub Ohm Vape Kit – What You’ll Need

In order to successfully Sub Ohm vape you’ll need four main things; a tank with a wide airflow, a Sub Ohm coil that’s compatible with your tank, a mod capable of providing enough power (usually at least 30w), and an eliquid high in VG (60% and above) and low in nicotine (6mg or below)

A wide airflow on a tank is needed to cool down the coil, and also to produce the large cloud of vapour. You’ll need a coil that’s capable of allowing a large amount of electrical current though, and also a mod that’s powerful enough to reach to around 30w. Use eliquids that are high in VG to get the best experience, as these particular eliquids create the smoothest vapour without the harshness that high PG can create.
