Sub Ohm Vaping

Sub Ohm Vaping

When in your local vape shop or speaking with other vapers you may have heard the phrase sub-ohming and be wondering what it is and if it is right for you. In this post we hope to answer any questions you may have about sub-ohming and help you make an informed decision on whether to give it a try.

What Is Sub-Ohming?

When you hold down the fire button on your e cigarette you send an electrical current through your coil. When this current gets to the coil it meets resistance, and if this resistance measures at less than 1 ohm (Ω) then this is classed as sub-ohm vaping. An atomiser built for sub-ohming will often be bigger than a higher ohm atomiser, as this allows for more cotton to be in contact with the coil, and more e liquid to be vaporised. In some cases, such as the Smok V8 Baby T8 atomiser which reads at 0.15 Ω and is best run between 60 – 80 watts, there are multiple internal metal coils within the atomiser, allowing the coil to be run at a higher wattage.

Why Move Onto Sub Ohming?

For some people vaping quickly goes from being a stop smoking aid to being a hobby. For these people the main appeal of sub-ohm vaping is more flavour and bigger clouds, many of the hobbyist vapers will tell you that they are chasing bigger and bigger clouds. It also produces a warmer vape, which some people prefer over the cooler vape of a higher ohm device.

Changes You Will Need to Make

Should you choose to begin sub-ohming there will be some things that you will first need to take into account.

Firstly, sub-ohm vaping could require a different inhalation technique than what you are used to. Most starter kits require a mouth to lung (MTL) pull, whereas most sub-ohm devices are better used with a direct to lung (DTL) pull.

Another consideration is that you may require a lower strength nicotine when sub-ohming. Due to the increased amount of vapour production the nicotine feels much harsher in a sub-ohm tank.

It is not unusual to find you go through e liquid much quicker once you start sub-ohming. Unfortunately, more vapour production equals more e liquid vaporised. A popular way to combat this issue is to move from using the single 10ml bottles that are popular with newer vapers, to bigger shortfill bottles.

E Liquid Tips

Finally, most people prefer a high VG e liquid in order to minimise the throat hit, that could be too harsh with a high PG e liquid. Another reason that high VG liquid is favoured by sub-ohmers is that it produces bigger clouds, further adding to the plumes a sub-ohm tank can produce.
