Guide to Sub Ohm Vaping

If you walk down the street in just about any city, you’ll probably see someone blowing out clouds a freight train would struggle to match. How are they doing it? Sub Ohm vaping. If you feel like you’ve clocked mouth to lung vaping and are looking for something a little more exciting, you might want to consider getting into Sub Ohm vaping. More power, more cloud and a whole lot more options - we’ll clear up all the terminology and tell you how best to try it out.


If you’re totally new to the whole vaping vocab, there are two main differences in style you need to know about. The first is mouth to lung (MTL) vaping. You’ll probably be familiar with this one - it’s the way people smoke conventional cigarettes and the same method you’d use for an entry level kit. It’s where you inhale some vapour into your mouth and then down into your lungs. This style is utilised by people with lower powered vapes with pods or coils that have a resistance of 1.0ohm or more.

DTL (direct to lung) vaping is pretty much just the exact opposite. You’re inhaling more quickly and breathing the vapour straight into your lungs. In order to vape this way you’ll almost always need a coil with a resistance of less than 1.0ohm. You’ll also need more power - so kits with bigger batteries and more wattage are the go to.

"The giveaway is in the name - Sub Ohm vaping is when you’re using an e-cig with a coil resistance of less than 1.0ohm"


That’s cool and all, but why do people actually do it? There are a bunch of benefits you’ll be able to enjoy with more power and a lower resistance coil:

  • Less throat hit. Mouth to lung kits are made to replicate the feeling and style of smoking - which goes hand in hand with the kind of liquid you use. When you Sub Ohm vape, you’ll need to change your vape juice choice (more on that later). In turn, you’ll experience a smoother inhale with a negligible throat hit, if at all.
  • More clouds. Again, with the e-liquid choice, more power and a faster inhale means the clouds you get from a direct to lung inhale are impressive. Depending on your set-up wattage wise and coil resistance, you could be blowing enough vapour to create a smoke screen and perform a disappearing act in your own living room.
  • Way better flavour. With more power comes more responsibility flavour. Direct to lung vaping pack a whole lot more flavour in that you’ll have ever experienced, making your experience more enjoyable.
  • More options for e-liquids. When you use a lower powered device with a plus Ohm coil, you’re usually going to stick to higher PG liquids and nic salts. Once you get into Sub Ohm vaping you’re opening yourself up to the wonderful world of high VG liquids and shortfills. There are more brands, flavours and unique flavour combinations to choose from than you’ll have ever had before.



We can hardly tell you about Sub Ohm vaping without talking about e-liquids (we’re E-Liquids Superstore for a reason after all). There are a couple of things you need to look at with your vape juice choice when you get into Sub Ohm vaping.

This is an important one, you don’t want to be getting head spins or end up feeling like you’re taking in far too much. When you use a Sub Ohm vape two things are different here: you’ve got a much more powerful device on your hands, there’s more vapour and you’re taking it straight into your lungs. All these factors combined means using a 6mg is going to hit more like a 10mg-12mg strength. Most of the time people find 3mg is fine which works out nicely as that’s the strength you’ll get when adding an 18mg nic shot to a 50ml shortfill.


When you use a mouth to lung device, you’ll typically use a 50:50 PG:VG ratio. There are a few reasons for this. The first one is that most people are looking to experience that throat hit feeling you get from smoking. PG is the ingredient that achieves this effect and it also serves to carry flavour. The second reason is that PG is more easily evaporated because it’s thinner in consistency. Mouth to lung devices like pod kits have less power and can’t function properly with high VG e-liquids. When you have more power in your vape with a low resistance coil, too much PG will produce a very harsh throat hit. Aside from that - more VG is going to give you much more cloud payoff which is probably at least part of the reason you switched over to a Sub Ohm vape.


Sub Ohm vaping is pretty simple once you get used to it and it doesn’t take long to adapt for most people either. You’ll only need a couple of things:

  • A vape with a Sub Ohm coil. Starting out with a 0.8ohm is fine though you can go as low as 0.1 or 0.15 with many tanks with replaceable coils). We recommend a vape pen to start with as they’re a good middle ground between a starter MTL kit and a heavier duty DTL kit.
  • A high VG liquid. Most people start out with a 70:30 VG:PG because it strikes the right balance between vapour and flavour.

The principle behind it is pretty simple. Fill up your tank in the same way you would with a pod or mouth to lung tank and let the juice settle for a while to saturate the coil. Then, when you activate the firing button you want to inhale more deeply and quickly straight into your lungs. You might have the odd cough or hiccup in the first few puffs but you’ll more than likely get the hang of it pretty quickly.

Once you start, chances are you probably won’t want to go back to mouth to lung vaping. More flavour? Check. More vapour? Double check. More fun? Absolutely. As you get used to it you can move to something like a box mod kit with variable wattage, more power and an even lower resistance for more of all the good stuff.
