Intro

Welcome to the realm of Sub Ohm vaping, known to most as just “Sub Ohming”. This has nothing to do with Sub-Zero from Mortal Kombat and everything to do with atomizers that are capable of firing at under 1 Ohm of resistance. At the end of the day, Sub Ohm vaping comes down to three words: big ass clouds. If that means anything to you, then you may want to look in to Sub Ohm vaping. Hopefully this article will help answer all of your questions and help you decide whether or not Sub Ohm vaping is right for you. If you just want a better tank with good flavor stick with your Nautilus. This is mostly for the extreme vapers.

Why Sub Ohm?

  • Huge Vapor Production – If you are looking to blow bigger clouds than the guy or girl next to you then this is for you.
  • Intense Flavor – Once you try a tank with a low-resistance (Sub Ohm) build using organic cotton wicking it is hard to return back to your high-resistance ceramic fiber or silica-wicked clearomizers.
  • Warmer Vapor – With higher wattage comes a slightly warmer vape. Of course the wide airflow help to cool this down so that it doesn’t burn your lips, but many people enjoy this warmer type of vape because it helps to simulate the experience of smoking traditional (analog) cigarettes.

Being that Sub Ohm vaping simply produce bigger plumes of vapor, this can also contribute to providing a mouthful of flavor with each puff. More intense clouds paired with rocking flavor is how it all started. Vapers began building lower resistance coils until they reached below 1 Ohm, hence the name, Sub Ohm. Soon it just became a race to the bottom as builders found new and ingenuitive ways to achieve lower resistance setups. Chances are if the guy in the vape shop is blowing bigger clouds than you, it is because he or she is running a Sub Ohm build. In other words, nobody will ever win a Cloud Comp with a build over 1 Ohm.

How do I Sub Ohm?

The vape game is picking up steam (no pun intended) and is rapidly changing. In the past, if you wanted to Sub Ohm this would first require buying a Mechanical or Box Mod that uses rechargeable 18650 batteries, Kanthal wire and organic cotton for wicking. A basic understanding of Ohm’s law and coil building was a must. Fortunately, these days all it takes to start blowing out colossal clouds is the purchase of a Sub Ohm Tank and pretty much any Mod on the market that can push out 30 watts or higher, such as the iStick 30W.

These are the main three ways that you can enjoy Sub Ohm vaping:

RDA’s (Rebuildable Dripping Atomizers) aka Drippers, were the original way people were able to Sub Ohm. These are usually smaller devices than tanks that attach to Mechanical or Box Mods. They contain a deck where coils are built and attached using a screwdriver and wicked with cotton. Users drip a small amount of juice directly on to the coils and wick before every few puffs.

RTA’s (Rebuildable Tank Atomizers) are for people who want to build coils but do not want to drip. RTA’s are essentially clearomizers that require the user to build the actual coil(s) inside. This gives them freedom to create a coil that will give them the exact type of vape they want. Recently many RTA’s have been geared towards the Sub Ohm vaper with the appropriate airflow options.

Sub Ohm Tanks, similar to RTA’s except that the coils are disposable and pre-made. This is a great option for people who are new to the whole Sub Ohm thing but do not want to start building. Sub Ohming has never been more accessible since the invention of tanks such as the Atlantis by Aspire and the Kanger Subtank Line. These tanks are getting closer to that RDA/RTA experience.

To Sub Ohm, or not to Sub Ohm?

Here are some reasons why you might NOT want to:

  • Mouth to Lungers – Some people just do not want that lung hit that Sub Ohm vapers live for. These people are often referred to in the vape community as mouth to lung hitters. These kind of vapers prefer a more constricted draw that emulates that of an analog cigarette versus a massive lung hit.
  • Stealth Vapers – Many people vape as a way to get their nicotine fix without having to actually smoke cigarettes. Sub Ohm vaping can draw a lot of attention to you when out in public so for that reason many people will stay away from it.
  • Juice Guzzlers – The bigger the cloud, the more juice it takes to produce. Therefore, Sub Ohming will require larger quantities of e-liquid which will cost more money than your standard setup. For those looking to conserve juice and save money, Sub Ohm vaping just might not be in your budget. Also keep in mind that you are probably going to want to lower your nicotine level when Sub Ohming because bigger vapor also means you are getting a bigger blast of nicotine. Most people that Sub Ohm tend to use lower than 6mg of nicotine and some even go with 0mg.

Is Sub Ohm vaping safe?

Are hammers safe? Nobody wants to hear this answer but: yes and no. If you are looking to get into Sub Ohm vaping, please educate yourself first. You do not need to major in electrical engineering but a basic understanding of Ohm’s law and basic electronics would greatly ensure the safest usage of these products. Read the instructions carefully and two words: battery safety! Do your homework and if you are too lazy to do any of this, talk to somebody knowledgeable on forums like Reddit and ask questions. Go to a local vape shop that you trust or read more articles about battery safety.

Sub Ohm Health/Safety

The safest way to enjoy the benefits of Sub Ohm vaping without the risk would be to use a regulated box mod such as the IPV4 or the Vaporfi Vox 2 with a tank such as the Atlantis 2 or Subtank Mini. Do not use a mechanical mod with a hybrid top cap when sub ohm vaping as this is very dangerous.If using a mech mod with a sub ohm tank, be sure that it is properly vented and never use an unvented mod.

Also be sure to use proper authentic batteries that are suited to sub ohm vaping. Most sub ohm vapers will use 18650 batteries and these can bought fairly cheaply from a trusted vaping vendor. We use Efest 35A 18650s in our box mods and mechanical mods. Be sure to never exceed the AMP limit of your batteries!

Do I have to Sub Ohm?

The truth is that Sub Ohm Tanks can also be used with lower wattage devices such as the iStick 30W, for example, by using the 1.2 Ohm coil heads. This is great for people who like the wider airflow options and the organic cotton aspect of a Sub Ohm tank without actually Sub Ohming. The truth is these tanks will still produce a ton of flavor and mountains of vapor with a slightly higher resistance coil head. This is another option for anyone who wants to upgrade to a Sub Ohm tank without having to go out and buy a new Mod.

Conclusion

Hopefully you now have a better understanding of what Sub Ohm vaping is all about. Don’t just follow the trends blindly. Do some research and think about whether or not this is for you. Like anything else, vaping started as a means of quitting cigarettes but has quickly evolved into a hobby. This hobby is now becoming into a sport much like people who rebuild cars for racing. Welcome to the fast and furious world of vaping!

  • Joey Gilbert

    can I use a 18650 3.7V 11.5Wh 3200mAh Li-ion Rechargeable Battery for sub ohm vaping?

  • Sam loops

    Hi I have a question about sub ohm I want to know if I buy joyetech ego one or the aspire cf sub ohm battery with the non removable battery or others just like that are those the same as Mechanical mod with removable battery are the joyetech and aspire are little safer then the Mechanical mod. I just trying to say do i need to follow the same rules as.

    • Both of those you mention were made to use with sub ohm tanks, so are safe to use. They work like mechanical mods. Mechanical mods with hybrid caps are the ones you need to stay away from when using sub ohm tanks.

      I would take a look at this regulated tube mod by Apollo:http://vaping360.com/apollo-v-tube-4-review-50w-regulated-tube-mod-capable-of-0-2ohm/

      You can adjust the wattage up to 50W and it fires down to 0.2ohm. This is in my opinion far superior when using a sub ohm tank, as you can adjust the wattage unlike those you mention above!

  • Hannah Lee

    Okay so I’m VERY new to the vape community and am looking into buying an eleaf istick 50W (50 being max wattage). I’m not buying a kit just the battery so the world is my oyster as for choosing the tank. I’m leaning towards the Atlantis 2, but my question is what would be the best coil to use at 30W?

    • Hi Hannah! Do note that the Atlantis 2 will be a direct lung style inhale, which if you are coming from smoking is something you might not be used to. If you want a mouth to lung style draw I would look at something like the Nautilus Mini. If you are happy with a direct lung inhale, then the Atlantis 2 is a good tank, although Aspire are launching a new one next month, which will be a top filler, so might be worth waiting on that. If you want the Atlantis 2 the 0.5ohm coil will work well at 30W. The new Kanger Subox kit might also be another good 50W option that comes with a good tank and looks pretty cool!

      I hope that helps.

  • casey

    hey how many mls would you be able to use on the nautilus minis coils before you need to change em

    • Hi Casey. This is a difficult question to answer as it comes down to many factors. You can probably get 2 weeks from one coil with medium usage.

  • yasmin

    I was recently given a IPV4S and a herakles by sense tank. Are these two safe together? Ive been reading about and realised the batteries in the set is not safe to use (ICR18650-26F samsung). Can you advise what battery I should purchase for the set up I have? Thanks!

  • David Davis

    Hello, I just got my first vape kit yesterday. I have only smoke a couple of cigs since getting this. But I want that big cloud of smoke. I have a ITaste MVP 3.0 30W MOD. AND A Ijust 2 atomizer tank. And just put in a sub ohm coil in it. Hits like a bitch now, but still can’t get that cloud. Any help would be great.

    • What is the resistance of the coil you are using? You might want to try a .3 ohm coil instead of .5. You may want to invest in a nice RTA or RDA if you are looking to get even bigger clouds.

    • Adam levine

      The Aspire Atlantis 2 tank is great for for sub-ohm cloud chasing without the hassle of having to rebuild your own coil. Use zero or low nicotine e-liquids if you’re into making vast amounts of vapour clouds.

    • PJ

      No idea if you’ve picked up advice elsewhere. Before sub ohming, you’re going to want a very good understanding of how watts, amps, and ohms work.

      In the meantime, if you’re looking for big clouds, use a juice that has a higher VG percentage. Bear in mind that VG is sweeter, so it will likely influence the flavor of your juice. But the higher the VG percentage, the bigger the clouds you’ll get.

  • Tonya

    Has anyone had the popping sound that comes with the I-sub G tank? Is that normal?

  • Joseph Carnes

    is running .1 ohms safe with a single sam 18650 with smpl mod and a rda? Joseph

    • Dave @ Vaping 360

      In my opinion, not really. Of course it does depend on the type of 18650 as some have higher amperage than others however, for the most part, I would not recommend it. My advice is to stay in the .3 range to be on the safe side.

    • To be 100% sure please take a look at our battery safety section: http://vaping360.com/category/guides/battery-safety/

    Hi, I have a Smok X-cube II mod with the Smok TFV4 tank. Currently using 0.22 ohm coil which came with the tank and the liquid I have is 75/25 but i’ve noticed I’m not getting a heavy cloud (pretty much the same if not less than what I was getting on my Joyetech EgoOne). How can I increase my vapor production and get thicker nicer clouds?

    • Dave @ Vaping 360

      How many watts are you vaping on? Try bumping it up! I would also try playing with the RBA section and learning how to build it. I’m getting huge clouds of pure flavor with TFV4 right now with a fused clapton coil at only around 30-40 watts, and it can handle way higher.

      -Dave

      • Doug

        I was vaping at 50 watts but I noticed that the puff setting on the smok was on soft. Bumped it up to hard now and getting a much thicker cloud. Also I think my air intake was too much before which was thinning it out. I will check the RBA articles and try and make a build eventually. Still quite new to vaping in general so I didn’t want to mess around too much. Thank you for your help!

      • João Garcia

        How is the right way to big clouds ? im with tfv8+xcube2. Is it necessary to use higher VG when sub ohming for big clouds ? or just sub ohming and 50/50 make big clouds ?

        U sad u are getting big clouds of flavour with 30-40wtts, how % the liquid ? and about the ohms ?
        @DaveVaping360:disqus

  • Saif Adel

    Hi, I’m using a reuleaux rx200 with a smok tfv4 tank and a tf-t3 coil head but the problem is after priming it correctly and filling the tank and leaving it for like 5 minutes to soak in the e juice after like 3-5 hits on 60 watts i get a burnt taste idk why please help.

    • Dave @ Vaping 360

      Hey sorry for the late response but try starting below 60W (probably around 20-30W), and working your way up every few hits next time you change your coil. Hope that helps!

  • Jayson Del Rosario Fernandez

    good day everyone! I’m using Cuboid 150W + iJoy Tornado T4
    0.45 ohms
    40watts
    9.43 amps
    other forum said that sub-ohm is very dangerous, do you think i should go with 1.0 ohms just to be safe? or i’m good with kind of settings?
    thank you

    • Dave @ Vaping 360

      They were most likely talking about using rebuildable atomizers and mechanical mods. You are not using either one so there is no major risks involved. Hope that helps!

      -Dave

  • Fred

    I have never read such a total load of hipster nonsense in my life. You people really hang around in ‘vape shops’ and care about who can blow the biggest cloud?

  • Aaron Bee

    I just started vaping and was wondering if i can vape a 70pg/30vg blend in a sub ohm tank?

    • Dave @ Vaping 360

      Yes, that sounds good to me.

  • Shannon

    I have a 40 watt battery with the Atlantis 2 tank is this safe

  • Gerry Elanda

    I have a 40A 3.7V AWT 18650 Batteries , using tesla invader 3 mod and 0.09 Ohm (24g kanthal A1 – parallel coil build)

    Is this safe ?
