If you’ve ever watched someone blow out a thick cloud of vapour and wondered how they do it, chances are they’re sub-ohm vaping. This style of vaping is all about maximising vapour and flavour – a step up from the standard experience many vapers start with. But what exactly is sub-ohm vaping, and is it something you should explore?

In this guide, we’ll walk you through the essentials of sub-ohm vaping – from what it actually means, to how it differs from regular vaping, and what kind of gear and e-liquid you’ll need to get started.

What Does Sub-Ohm Vaping Mean?

The term “sub-ohm” refers to the resistance of the coil inside your vape device. In basic terms, when the coil has a resistance of less than one ohm, it’s classed as sub-ohm. This lower resistance allows more electrical current to pass through the coil, which in turn heats the e-liquid faster and more intensely. The result? Bigger clouds, bolder flavour, and a warmer vape overall.

But sub-ohm vaping isn’t just about the coil – it represents an entirely different style of vaping. Unlike the typical mouth-to-lung (MTL) approach that mimics smoking, sub-ohm vaping is direct-to-lung (DTL). This means you inhale vapour straight into your lungs, similar to taking a deep breath, making the experience much more intense and immersive.

How Is Sub-Ohm Vaping Different From Standard Vaping?

The differences between sub-ohm vaping and traditional MTL vaping are significant – not just in terms of the experience, but also the equipment and e-liquids used. Standard vaping typically uses higher-resistance coils and lower wattages, producing a modest amount of vapour and a stronger throat hit. It’s ideal for those who prefer a discreet vape or are looking for a sensation similar to smoking.

Sub-ohm vaping, by contrast, is designed for those who want to push their vape to the limit. The vapour is thick, the flavour is rich, and the overall draw is far smoother. It’s a popular choice among seasoned vapers who enjoy the performance aspect of vaping – whether for cloud competitions, flavour exploration, or simply a more satisfying hit at lower nicotine levels.

What Do You Need for Sub-Ohm Vaping?

If you’re thinking of making the switch to sub-ohm, it’s important to understand the gear involved. Not all vape kits are built for sub-ohm use, and using the wrong setup can lead to poor performance or even safety issues.

Sub-ohm vaping starts with the right device – typically a more powerful vape mod or kit that supports adjustable wattage and airflow. These devices are capable of pushing enough power to handle the demands of low-resistance coils without overheating or draining the battery too quickly.

Speaking of coils, these are usually rated somewhere between 0.1Ω and 0.5Ω and are specifically designed to produce more heat. This higher output means they vaporise more e-liquid with each puff, which brings us to another key part of the setup: high-VG e-liquids.

Vegetable Glycerine (VG) is a thicker ingredient that produces dense, silky vapour. Sub-ohm vaping relies on e-liquids with at least 70% VG content, as these can keep up with the high power levels and fast vapourisation rates. Thinner, PG-heavy juices just won’t cut it – they’re more suited to MTL vaping and can cause dry hits or leaking in sub-ohm tanks.

Finally, you’ll need a strong battery setup. Many sub-ohm devices use external batteries or have built-in cells with high mAh ratings to deliver consistent power. Understanding battery safety is essential here, especially if you’re using mechanical mods or building your own coils.

Superior Vapour stocks a wide range of sub-ohm kits, high-VG e-liquids and compatible accessories, so whether you're upgrading or diving in for the first time, you'll find everything you need in one place.

Why Choose Sub-Ohm Vaping?

There’s a reason sub-ohm vaping has become a go-to for many experienced vapers. First and foremost, the cloud production is unmatched. If you enjoy making big, dense clouds or simply like the visual appeal of vaping, sub-ohm setups deliver in spades.

Beyond the spectacle, sub-ohm vaping also offers a noticeably richer flavour profile. With more heat and more vapour, e-liquids reveal deeper layers of taste that are often muted in standard setups. Many vapers find that they enjoy their favourite flavours even more when vaping sub-ohm.

Another perk is the smoother draw. Thanks to the high VG content and the DTL inhale style, sub-ohm vaping tends to feel less harsh on the throat – even at lower nicotine strengths. In fact, most sub-ohm vapers use juices ranging from 0mg to 6mg of nicotine, since the volume of vapour makes higher strengths too intense.

However, it’s worth noting that all this power and performance comes at a cost. Sub-ohm vaping uses up e-liquid much faster than MTL vaping, and your device’s battery will need charging more frequently. It's also not the most discreet option – both in terms of vapour production and the size of the devices.

Is Sub-Ohm Vaping Right for You?

Sub-ohm vaping isn’t for everyone, and that’s absolutely fine. It’s best suited to those who’ve already spent some time with vaping and want to take things to the next level. If you’re someone who enjoys experimenting with flavours, wants a smoother inhale, or simply likes the idea of big clouds, sub-ohm could be a great fit.

On the other hand, if you’re just starting out, trying to closely replicate the sensation of smoking, or prefer a more portable, subtle vape, then you might be better off with a standard MTL setup. Sub-ohm vaping involves a bit more maintenance and knowledge, so it’s not usually recommended for complete beginners.
