Beginners Guide To Sub-Ohm Vaping Beginners Guide To Sub-Ohm Vaping

Even some longtime vapers don’t understand what exactly sub-ohm is and why it matters.

Sub ohm vaping or sub ohming is a method of vaporizing done at resistances lower than 1.0 Ohms. This technique produces the largest clouds possible and is often used by professional cloud chasers. Our guide is perfect for anyone curious about sub ohming but who isn’t quite ready to invest in a whole new setup. Be warned though, the clouds produced with sub ohm atomizers are incredibly large and potent. They are not meant for those merely looking for a higher quality vape; sub ohm is first and foremost a method of creating the largest possible clouds.

Ever since the invention of personal vaporizers, advanced users have sought ways to maximize their cloud size and flavor. Vapers would build lower and lower resistance coils until they reached the sub-1.0 mark, hence sub ohm vaping. After that, it only continued to drop as new advanced techniques allowed for resistances as low as 0.1 ohms! Working at those type of resistances produce beastly clouds regarding both flavor and size. These days it is essential to use a sub-ohm vaporizer if you want to compete in any cloud chasing contest. It’s also a must if you’re looking for the most intense flavor or mouthfeel possible. Nothing quite compares to the power of a sub ohm cloud. So if you’ve always wanted to make insanely big clouds, or never felt like regular vaping was doing it for you, sub ohm vaping is something you may want to try. Read on for our overview of everything you need to know!

How It Works

It use to be quite an undertaking to successfully sub ohm vape. Wanting to do it safely would require a mechanical box mod with external batteries, and specific wire and cotton build. Using a rebuildable dripping atomizer (RDA), the user would secure the coil down using a screwdriver, then thread the cotton inside for wicking. You then drip a small amount of e-liquid directly onto the cotton wick and coil combination. Most importantly, it was vital to have a solid grasp on Ohm’s Law to sub ohm vape safely. While it’s still a good idea to understand something about Ohm’s Law, these days all that is really necessary is a sub ohm tank and any current box mod. With as little as 50W or lower of power, sub ohm vaping is well within reach.

Sub ohm tanks use disposable, premade coils, making them perfect for any beginners who want to give sub ohming a try. This type of tank expanded the accessibility of sub ohm vaping, but rebuildable tank atomizers (RTA) gave advanced users the chance to build custom setups but do so with a tank. Original RTA’s were made for regular vaping, but over the last few years, in particular, most RTA’s are optimized for use with sub ohm resistances. We even have hybrid RTAs now that are mainly a cross between old-school dripping and new school tank sub ohming. There are some who ought to steer clear of sub ohming altogether. Especially those who prefer high nicotine content in their liquid, as you are taking in a lot more nicotine through sub ohm vaping. Most professional cloud chasers use e-liquids without any nicotine at all. Also for obvious reasons if you need to keep a low profile when you vape then sub ohming is just probably not for you.

Safety First

Most any activity can be dangerous if done improperly and without much discretion. This is especially true for vaporizers, as they consist of batteries and heating elements that can be harmful if they fail. That’s why it’s important to understand basic battery safety to sub ohm vape correctly. The first place anyone interested should start is with some good old fashion research. Read the manual carefully, paying particular attention to the safety rules. For instance, one thing that is never safe, no matter what type of equipment you have, is to use a hybrid mechanical mod with a tank not made for hybrid use. Like with most things, it’s best to be sure before doing anything that could be dangerous. You should always check your batteries and components for cracks or damage of any kind. This sort of issue is one of the leading causes of failure, and can quickly snowball into something that will put you at serious risk. But if you’re sure to use caution and diligence whenever operating your mod, sub ohm vaping is as safe as anything.
