Vaporescence's Guide to Sub-Ohm Vaping

The vaping industry has been enjoying quite the prestige and attention in the past several years. While regular vaping provides a pleasurable experience to many vapers, there are still others who want bigger clouds and richer flavors and they are able to achieve this through sub ohm vaping.

What is Sub Ohm Vaping?

Some people also refer sub to ohm vaping as sub ohming. The principle of sub ohm vaping is simple: you vape with a device that’s built to accommodate a resistance of less than one ohm (1 Ω). Anything over one ohm is considered as regular vaping. However, the simplicity ends there as sub ohm vaping is a complex concept that each vaper needs to fully understand before taking the plunge.

Sub ohm vaping is rather a controversial subject in the vaping community. In as much as the vaping industry aims to provide a fun, pleasurable yet healthy alternative to smoking, sub ohm vaping presents a different set of unique challenges.

First, it can be potentially dangerous to new vapers or people who don’t know what they’re doing. A sub ohm vaper is in risk of possible fire or explosion if he pushes the battery beyond its limits. It's important to note that this type of vaping is not for everybody and you should take the time to learn and be willing to exercise caution in order to proceed with sub ohm vaping safely.

Difference Between Sub-Ohm Vaping & Regular Vaping

There’s a whole lot of physics involved in both regular and sub ohm vaping, but to make things a little simpler, here are the most noticeable differences between the two:

Sub-Ohm Vaping Requires Specific Devices

You can vape regularly with any vaping device. Whether you prefer a disposable device, vape pens, or complex box mods, the vaping experience is fairly standard across the board. People who are just started to vape usually begin with a simple disposable e-cig and, if they like it, they graduate to more sophisticated devices for a better vaping experience.

On the other hand, sub ohm vaping usually requires specific devices in order to do it safely. Some vaping devices aren’t really engineered to handle less than one ohm of resistance. This poses the risk of fire and/or explosion because the device isn't being used for its intended purpose. In order to address this safety issue, some vapers build their own sub ohm device using specialized tanks, clearomizers, wicks, and batteries.

You Get Bigger Clouds With Sub-Ohm Vaping

One of the most exciting aspects of sub ohm vaping is that you will be able to produce larger, fuller clouds that regular vaping just can't do. If vaping discreetly is a concern, you have decide whether sub ohm is the right way to go for you (or just have two sets of gear).

Sub-Ohm Vaping Uses More eLiquid

Since a sub ohm vaping device heats up the e-liquid quicker causing more of it to turn into vapor, more e-liquid will be used up in a shorter amount of time. Since you’ll be heating the device at a much faster rate, you'll also be replacing your batteries more often (or you’ll have to grab some premium quality rechargeable batteries). This can make sub ohming more expensive than regular vaping. It's part of the gig.

Benefits of Sub-Ohm Vaping

Most people who have been vaping for quite some time end up exploring the realm of sub ohming. Here are the most notable benefits and advantages of sub ohm vaping.

  1. Fatter, thicker clouds. Sub ohm vapers usually have the penchant for bigger and billowy vapor. With the help of a bigger coil and wick as well as more powerful battery, your sub ohm vaping device heats up the e-liquid faster resulting in fatter, thicker cloud. Sub ohm is also the device of choice in cloud chasing competitions. However, if you want to vape discreetly, sub ohm may not be for you.
  2. Richer flavors. Sub ohm vaping unlocks more flavors than regular vaping, for the very same reason that it can produce bigger clouds. Each drag contains more e-liquid, thus making the flavor more pronounced.
  3. Warmer vapor. Also following the very principle why sub ohm vaping produces bigger clouds and more intense flavors, sub ohmig also produces warmer vapor. When the coils heat up a larger portion of the e-liquid, you’ll drag in warmer vapor. Some vapers prefer the sensation of warmer vapor into their lungs, while others may not like it.
  4. Less Nicotine. If you’re looking into lowering your nicotine consumption while vaping, sub ohming may be right for you. Using a sub ohm tank will mean you will be getting more nicotine than from a regular vaping tank. Vapers who vape at 18mg nicotine find it better to vape sub ohm at much lower nicotine level in order to normalize the nicotine hit they get. This can be good for people who are looking to reduce their nicotine levels without suffering from withdrawal symptoms.

How Sub Ohm Vaping Works

The very first thing that you need to know in sub ohm vaping is both Ohm and Joule’s law. Simply put, when your device increases its overall power output, the coil’s resistance also drops. The coils will need to work extra hard to heat up the e-liquid, putting some strain into the batteries.

With lower resistance and higher wattage, the demand for power is greater. Higher wattage means the juice is heated much faster, but lower resistance also means straining the batteries. It is therefore highly important that you don’t exceed the recommended amperage of your device in order to vape sub ohm safely.

Requirements for Sub Ohm Vaping

The success of your sub ohm vaping experience will depend largely on three factors: your mechanical device, the battery, and the e-liquid.

Sub Ohm Vaping Mechanical Devices

Regular vaping devices aren’t the best choice for sub ohm vaping simply because they come with pre-set amperages and resistances. Nowadays, you can vape sub ohm with these three devices:

  1. Rebuildable Dripping Atomizers (RDAs): These devices are also called drippers wherein a tank is attached to a box mod. With RDA, you will be able to build your own coil with a resistance you desire. Before taking a drag, you will drip a small amount of juice into the coil and wick.
  2. Rebuildable Tank Atomizers (RTAs/RBAs): These devices still allow you to build your own coil without having to drip the juice every so often. With RTAs/RBAs, there’s a tank that holds the e-liquid, instead of the traditional reservoir that comes with RDAs.
  3. Sub Ohm Tanks: These devices come with pre-made coils and wicks, eliminating the need to build your own. Sub Ohm tanks are especially ideal for people who have just started vaping sub ohm and are still learning their way around.

Sub Ohm Vaping Batteries

The battery is one of the most important parts of sub ohm vaping. Your battery supplies power to the device and if the batteries are pushed too hard, they can become overheat to the point of fire or explosion.

It is important that your mod is equipped with a battery that’s safe and efficient enough to meet the demands of sub ohm vaping. For sub ohm vaping, you will mostly need an IMR battery rated between 15 – 30A. IMR batteries are also the best option because of their high discharge capacities and safer chemical makeup.

Sub Ohm Vaping E-Liquids

The choice of e-liquid can also have a profound impact on your sub ohm vaping experience. Unlike regular vaping where the base of your e-liquid is a typical mixture of PG and VG, you will need maximum VG in your juice for sub ohm vaping. VG is essential to making bigger and fatter vapor when you exhale from your vape. Furthermore, more VG also helps lessen the throat and lung hits, making the vapor feel smoother (and not harsher). It’s also important to pick an e-liquid with lesser nicotine content to reduce hit. If you’re looking for the best juice for sub ohm vaping, there are tons of vendors offering maximum 100% VG both in store and online.

Risks of Sub Ohm Vaping

People often ask, “is sub ohm vaping dangerous?” The truth is, there’s no straightforward answer to this question. Yeah, vaping itself is inherently risky, but knowing what you’re doing plays a very important role in doing it safely.

First, you need to consider that sub ohm vaping involves a great amount of physics. You don’t have to be a genius in the subject, but you have to at least understand the Ohm’s law and its very important role in keeping sub ohm vaping safe. It’s also critical that you only use the appropriate mods, batteries and other devices especially if you’re trying to build your own sub ohm device from scratch.

For many people, building their own sub ohm device is half the fun in vaping; the other half is seeing how big of a vapor cloud they can produce from their masterpiece. A lot of vapers have succeeded building their own devices for sub ohm vaping, but this also takes skill and knowledge. You might be tempted to make your own as you go deeper the vaping rabbit hole, but do proceed with caution. Your device could explode in your hands or mouth if you build it incorrectly or push it beyond its limits. Know your battery’s limits and only vape within it.

The best advice would be to approach vaping slowly and with caution. Start out with regular vaping and see if you like it. Learn the ropes as you go and only go sub ohm when you know exactly what you’re doing.

Best Practices for Sub Ohm Vaping

In order to continue sub ohm vaping safely, here are the most important practices that you need to keep in mind:

  • Don't use cheap, sub-standard batteries. Don’t mind the savings if it’s your life on the line. Instead, invest on standard best quality batteries that are specifically designed to meet the needs for sub ohm vaping.
  • Measure low ohm resistance with a dedicated device. Generic and cheap multimeters could show the wrong ohm measurement and lead you to build a sub ohm device that’s potentially dangerous.
  • Monitor your batteries regularly and check for any signs of stress; 1) the batteries discharge quickly, 2) the batteries display higher voltage drop.
  • Regularly inspect the condition of your mod. Use a known and reliable battery, check if the mod’s discharge is higher than usual. Check all the connections and disassemble the device if required and determine where the problem lies. This can be a little time-consuming but it’s also critical to keep using your mod safely and efficiently.
  • Keep your mod as simple as possible. You may have to pass on certain features that a sophisticated mod carries, but if you’re just starting out, it’s always best to stick with the basics.
  • If your mod has a spring-loaded switch, make sure to check its stiffness regularly. Replace the spring when it’s starting to feel soft and weak.
  • Make sure that your mod is well-vented to allow air flow and gases to escape. An unvented mod is like an accident waiting to happen.
  • Keep your mod clean. It helps ensure good airflow and ventilation and prevent potential clogs and malfunctions.
  • Avoid overloading your batteries. Replace them on a regular basis to ensure that your mod is safely powered by a high quality battery.

Sub Ohm Vaping: Is It For You?

Sub ohm vaping may or may not be right for you. Like vaping, sub ohming is a matter of personal preference and decision. Obviously, sub ohm vaping is a whole new level in vaping and it can be potentially rewarding or dangerous depending on how you treat it. As long as you keep safety in mind and invest in good quality sub ohming products such as what Vaporescence offers, sub ohm vaping should be a fun and pleasurable experience for you.
