What is Sub Ohm Vaping?

Ever seen a vaper exhaling big plumes of vapour and wondered what it’s all about, or heard the term ‘sub ohm’ but have no idea what it means? In short, sub ohm is vaping using a vape kit with particular specifications, which creates large clouds of vapour.

What Are The Benefits of Sub Ohm Vaping?

  • Produces thicker clouds of vapour than standard kits
  • Warmer vapour
  • More vapour means more nicotine in one hit, which can be more satisfying
  • Greater range of kit options

Is Sub Ohm Vaping Safe?

Initially, sub ohm vaping was only really accessible to experienced vapers who understood Ohms Law and had a technical knowledge of how e cigarettes work. The wrong combination of power and resistance in a coil can be dangerous so this form of vaping was only pursued by very experienced users.

Sub ohm vaping is now much more accessible and kits are regulated to ensure safety for users. Some kits come with batteries that allow you to adjust various settings, for example the wattage and voltage outputs. Others are simple to use and already set up for a great sub ohm experience with just the press of a button. Examples of great beginner sub ohm kits are the Aspire PockeX & the Innokin Adept Kit, both available from our online store.

Provided you follow safety guidelines for e cigarettes and batteries and buy a kit from a reputable supplier, then sub ohm vaping is just as safe as regular or ‘classic’ vaping.

What Else Do You Need To Know Before Buying Your First Kit?

Styles of Vaping – Mouth-to-Lung (MTL) and Direct-to-Lung (DTL)

As a general rule, sub ohm kits will provide a direct-to-lung vaping experience. This simply means that you should inhale the vapour directly into your lungs.

Classic kits are suited to the mouth-to-lung style of vaping. Mouth to lung vaping is similar to how a cigarette is smoked, where the vapour is inhaled into the mouth, then into the lungs. With this in mind, we recommend that you choose a classic kit if you are completely new to vaping.

Sub ohm vaping can take a little getting used to. If you find you cough when trying a sub ohm kit for the first time, practice inhaling the vapour directly into your lungs. Also, make sure that the nicotine strength isn’t too high. As mentioned above, the nicotine delivery is faster with sub ohm kits so you generally won’t need as much nicotine as you would with a standard kit.

Which E Liquids Should You Use With Sub Ohm Kits?

The main ingredients in e liquids are Propylene glycol (PG), vegetable glycerine (VG) and flavourings. Some vape juices will also contain nicotine which will be stated in mg on the product packaging.

It’s important to know a little about PG and VG as the ratio of these two ingredients in an e-liquid determines which kits and/or coils it is suitable for.

Sub ohm e liquids will contain a higher ratio of vegetable glycerine (VG); usually 60% and above. The OK Vape range of Sub Ohm e-liquids have an 80VG/20PG ratio.

Classic e-liquids will contain a higher percentage of propylene glycol (PG) and are suitable for classic (mouth-to-lung) kits. The OK Vape Classic e-liquid range has a 70PG/30VG ratio.

You can also purchase vape juices with a balanced 50/50 ratio of PG & VG. These are generally well suited to most kits and tanks so are a great option for most. However, these might not be suitable if your tank is using coils with a very low resistance.

Using high PG juices in a sub ohm tank or kit will generally produce a harsh vapour and burnt flavour and vice versa for high VG juices in a kit designed for classic vaping.

You can find out more about e liquid ingredients on our ‘What is PG/VG’ page.

Which Nicotine Strength is Best for Sub Ohm Vaping?

As mentioned above, the increased volume of vapour with sub ohm means you will need to use a much lower nicotine strength. The most common nicotine strength for sub ohm vapers is 3mg (0.3%). If you’re new to vaping, you may want to try 6mg, or use a short fill e liquid where you can add your own nicotine to get the desired strength.

More information regarding choosing a nicotine strength can be found in this guide.
