How to Sub Ohm and Blow Big Clouds of Vapor

What is sub ohm vaping?

Sub ohm vaping, also known as sub ohming, is a style of vaping that produces large clouds of vapor. Sub ohm devices utilize low resistance coils that are less than one ohm, hence the name sub ohm. They also provide enough airflow suitable for direct lung inhalation. Sub ohming typically requires vape mods capable of putting out a minimum of 40 watts, but the higher levels can reach and exceed 200 watts.

Around 2014, sub ohm tanks began to dominate the market. Sub ohm vaping became the default standard for most new vapers until around mid-2016 with MTL coming back in style. Now the market is more diverse, with a broader range of vapes for every style of vaping.

The term sub ohm has evolved over the years with the technology. It typically refers to direct lung devices with coils that are 0.5 ohms or lower. Technically there are mouth to lung coils below 1 ohm found in devices like pod vapes, but those are not considered sub ohm because they’re low-power devices designed for stealth vaping.

Learn more about sub ohm vaping and cloud chasing in the guide below, and decide if it is right for you.

Advantages of sub ohm vaping

Aside from just big clouds, there are many other advantages of sub ohming over other styles of vaping.

  • Intense flavor: Sub ohm coils are capable of vaporizing a lot of e-liquid at a time, so your taste buds get hit with tons of flavor with each puff.
  • Warmer vape: Some vapers enjoy a warmer vape, which is easy to attain with sub ohm vaping, especially with high-wattages and low-ohm coils.
  • More airflow: Sub ohm vaping goes best with a direct lung inhale and unrestricted airflow. More airflow is necessary for cooling down the higher heat produced from the coils.
  • Big clouds: Blowing clouds appeal to many vapers. For the biggest cloud production, sub ohm vaping is a must. Sub ohm devices are a prerequisite for becoming a competitive vaper.

What is cloud chasing?

Cloud chasing is the act of blowing huge clouds with a vape. Cloud chasers are constantly trying to invent new ways to produce the biggest clouds of vapor. That means lower ohm coils, higher wattages and tons of airflow. Cloud chasing requires knowledge and experience in order to be done safely and properly.

Not all sub ohm vapers are necessarily cloud chasers, but cloud chasers are most certainly sub ohm vapers. Sub ohming is the only way to achieve such voluminous cloud production. Cloud chasing has become more accessible today with the popularity of sub ohm vape tanks because it doesn’t require as much knowledge as before.

Still, safety is extremely important! That means having a good understanding of Ohm’s law and battery safety. Cloud chasing can be fun and enjoyable if done properly and respectfully.

Best cloud chasing vapes

The easiest and safest way to start cloud chasing is to get a sub ohm vape pen like the Mig Vapor Morpheus. It comes with a tank and powerful battery all in one and is very easy to use, even for beginners. They make it very simple to get started right away, without having a ton of knowledge.

If you want something more advanced, the best combo for clouds is a high-wattage box mod paired with a rebuildable atomizer, preferably a dual-coil dripper. There are also rebuildable tanks that are geared for sub ohming and some great sub ohm tanks that don’t require a ton of experience to use. A lot of these modern subtanks utilize multiple mesh coils which allow for high wattages and rich dense clouds.

How to get bigger clouds of vapor

Use appropriate batteries: Shop for batteries with high amp ratings, suitable for high wattages.

Keep airflow all the way open: Most sub ohm devices come with adjustable airflow. Generally speaking, the airflow should be at its most open setting to achieve the biggest clouds for the atomizer you’re using.

Use max VG vape juice: While PG and VG both make vapor, the higher the content of VG in your juice will allow for the biggest clouds. Consider it high-octane fuel for your tank!

Use a mod with power above 40 watts: When sub ohming, you will want a lot of headroom for power. You likely won’t use it all, but being able to go up an additional 10 watts or so can make a big difference in your vapor volume.

Use a somewhat forceful and fast draw: Along with using unrestricted airflow, the speed and forecefulness of the drag will increase cloud production. A bigger and faster draw will also aid in keeping the coils cooler.

Use coils rated below 0.5 ohms: Low resistance coils that are 0.5 ohms and below can handle more wattage and generally produce bigger clouds.

Best coil builds for clouds

Here are some videos they will show you how to build coils for some serious cloud production.

In part 2 of Rip Tripper’s Cloud Chasing 101 series, he teaches you how to do a simple cloud chasing build and goes into more depth about proper inhale/exhale technique.

In this video, Twisted Messes shows you how to do his signature 26 gauge twisted dual coil.

Sherlock Hohms shows you how to do a cloud chucking fused clapton for cloud chasing.

Originally, cloud chasing was done almost exclusively with low-ohm coils on a mech mod. Eventually builders realized they could use two strands of wire to create an ultra-low resistance coil, with tons of surface area, which eventually gave way to twisted and parallel dual coil builds.

Cloud chasing has advanced with the popularity of powerful regulated mods and exotic coils. Cloud chasers no longer need to build to the specifications of their device and batteries. Now they can just chuck big, beefy coils on any regulated high wattage mod, giving them more freedom than ever before.

Dual coils are standard for clouds but many vapers have taken that to the next level with triple and even quadruple coil configurations. This cuts the resistance down and greatly increases surface area. Fused claptons, aliens and other exotic builds are also very popular these days for cloud chasing.

What is competitive vaping?

In competitive vaping cloud chasers compete with each other to see who can create the biggest clouds and pull off the best vape tricks. Just like any hobby or sport, some people are going to be competitive, so cloud chasing is no exception. Competitions are held all over the world for cash prizes and endorsement deals. The US is home of many of the bigger cloud comps like the VC Cloud Chasing Competition, with the prizes ranging from custom gear and sponsorships, to thousands of dollars in cash.

Competitive vaping started as a way for vapers to express themselves and spread awareness about vaping. These days, it’s rampant in nearly every major city. Professional vapers gain fans, money and sponsorship deals through these meet-ups at local shops and vape conventions. Social media sites like Facebook and YouTube have played an instrumental role in the popularization of competitive vaping.

Public spaces are not meant for cloud blowing unless there’s reason to believe it won’t cause a problem. For example, at an outdoor concert with a tolerant audience. In general, most non-vapers don’t understand what the vapor is or isn’t, so it’s advisable to not literally put it in their faces.

Born in Brooklyn, New York, Dave has always had a passion for helping people quit smoking. As a former smoker himself, he knew how hard it could be. As soon as he learned about vaping, he instantly became obsessed with it and helped many people stop smoking. Vaping360 has given Dave a platform to do this on a much larger scale, by educating the public about the wonders of vaping.

I have a rig V1 with a dead rabbit rda, Im using a single green Samsung 3.7v 2500mah 18650, what is the lowest build you would recommend before it gets to be dangerous?


need some help please.

I reside in Sri Lanka all vaping product is banned therefore have to buy on the black market or have your goodies hand carried in.

Im a neweee to vaping trying to give up the 2 packs a day I initially bought a vipato P111 which stopped working after 4 weeks fire button not working …… no guarantees I got it out of hand.the tank came with two atomisers both failed in few days. I then bought a eleaf atomiser which really works well but the pod failed . now got a Ijoy quad I’m really trying to find out how to use the thing as I’ve just now got it in my hand. I have lots of juice and coil wire and now can re build a coil etc but need to understand how to gear this mod to use the wire I have obtained namely vapour tech nic 28 gauge to get the best vape ?

Dave Kriegel

Hey John, that’s terrible that vapes are restricted in Sri Lanka! I understand you have the iJoy Quad, juice and wire… which atomizer do you have? You will need either a rebuildable tank or an RDA.

And this guide will get you started making coils in no time.


i have teslacig xt mini 220W mod with vaporesso skrr tank i use 0.15 ohm 65 watts in mesh coil is it good combination for bigger clouds or not? kindly inform mee i am wating..

Dave Kriegel

Hey Abdullah, that sounds like a great combination for big clouds. The SKRR tank can actually handle even higher wattages, especially with the 0.15 coil, so you can bump it up a few watts until you get the amount of clouds you desire. Just don’t go too hot or you will burn your coil out. I hope that helps, best of luck.


Can we please stop promoting cloud chasing. These are the people that will get vaping banned from everywhere again. Blowing crazy clouds, stop acting like a 5 year old, it’s not cool……


So blowing clouds is grounds for criminalizing vapor? Sorry but that’s just foolish. People have been smoking disgusting smelling cigarettes in public since the beginning of time. They kill people and have caused burns and fires everywhere yet they are still around. Vapor is infinitely healthier, smells good, doesn’t kill people, doesn’t burn shit, and helps people quit smoking. How can anyone justify banning that over cigarettes just because the clouds are bigger? Silliness.


Hello. I am not here to get into sub ohm vaping but would really appreciate it if someone could tell me the ohm of a juul pod coil. Thanks! Anything helps.

Jim McDonald

Somewhere between 1.5 and 2.0 ohms.


is ijoy captain pd 270 with geekvape blitzen safe to go all the way down to 0.05ohms cuz like i made the coils that fit perfectly . im not so sure bout it as it has those tesla like batteries -20700


Hey, I just got my new Innokin Riptide Crios Starter Kit, its a sub ohm, and i believe its Mech mod too, so i want to know more about the safety and i heard that if i firing it for too long it can over heat and explode?

Dave Kriegel

Hey Kezia, congrats on the new setup! It looks like a really nice kit. The Riptide Crios kit is not a true mech mod, but it is made to look and perform like one. Your mod has built-in safety features and a chip that regulates the power output.

It will not overheat and explode from firing it too long, plus it will cut itself off at some point. Make sure it is off when not in use and don’t leave it in extreme cold/hot temperatures.

Innokin is known for making some of the safest products on the market so I wouldn’t be scared of that happening, but of course always take the proper safety precautions. If you would like to learn more about mech mods check this out:


Hey everyone. I have a Vaporesso Swag Kit 80W with an NRG SE tank. My current coil is a GT4 .15 Ohm (though my display reads it at .17 Ohm). I generally vape on Normal Mode, but I have been using CCW mode with an “A” shape ramp up (I heard this is a good setup for chain vaping?)

Is this sub Ohming? A 2-3 second hit at 70W with max air flow just doesn’t seem to produce as big a cloud as it should. Also the cloud isn’t very thick/heavy. The juice is a house juice and I don’t know the PG/VG ratio. (VG produces more cloud, correct? I can never remember which is which. Is PG more for flavor?)


Thank you I understand now. Vaped for a year until these sub ohm tanks took over and I was back to smokings ciggs. Now I know to get my wicks above 1 ohm and it keeps me from smoking.


eleaf istick tc60w melo 2 tank with aspire atlantis 0.5 Ω–is this safe? please suggest me..

Alessandro Marcheselli

Hey, newbie here, i need a quick tip: i purchased an alcohol-free, max vg liquid which is “compatible with sub-ohm tanks”, i have a Smok micro tfv4 tank is it fine or do i need to buy another one?

Robin Bartels

The SMOK TFV4 is fine to use, since it is a sub-ohm tank. In case you want to check some newer sub-ohm tanks out you could also go to

Lucas Torstensson

I’m using the Cuboid 150W with the tfv4 tank and the quadruple coil that is at 0.15Ω. I’m very new vapor I have maybe been vaping 3-4 months and I’m vaping on 80-90 watts and I’m wondering if I can use 80/20 VG/PG or even 90/10 VG/PG e-liquids?? And how long do you think I can Use it until I should change coil?? And because I’m so new vapor I was also wondering if you know how to get in to RBA coils and wicking because I don’t think We have any vape stores here and if you know any webbsites That can help me and things like That and I also Would like to know what you think and if you think I should change something or have some advice to a new vapor


Best way I found to learn yo rebuild coils or to build coils is watch videos on Youtube. Just put what tank your trying to rebuild for in the search engine. Watch the videos and practice building.


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 ?


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


I am using a Uwell crown, .5ohm ni coil temp set at 450F. on a wismec 100w. I find that I burn thru coils every 2 days. I am home and a heavy hitter. How can I make my coils last longer?


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

Dave Kriegel

Yes, that sounds good to me.


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?


I understand your confusion, but the point in blowing big clouds is for people who are trying to do tricks and create very thick clouds. As it was talking about this is for cloud blowing competitions that can win you large amounts of money. Its not like they want to show off their big clouds its that they want to have very thick clouds, for more visible tricks.

Jayson Del Rosario Fernandez

good day everyone! I’m using Cuboid 150W + iJoy Tornado T4
0.45 ohms
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 Kriegel

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!



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 Kriegel

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!


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 Kriegel

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.



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 ?


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!


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

Alex Kendell

To be 100% sure please take a look at our battery safety section:

Dave Kriegel

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.


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


It’s the sound of lubrication.

Alex Kendell

Yes, this is normal.


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.


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.


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.

Dave Kriegel

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.


If you’re worried about the extra heat burning your juice, don’t worry. There is more heat overall, but each specific point will be receiving the same amount of heat. The extra vapor is produced by the fact that it is spread out over a bigger surface area.

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!


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

Chris Kendell

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.


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?

Chris Kendell

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.
Best regards


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.

Chris Kendell

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:

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!


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

Dave Kriegel

Sorry for the late response but no, I don’t think those are suitable for vaping at all. Try Sony VTC4’s or VTC5’s for Sub-Ohm vaping.

Alex Kendell

Hi @disqus_7amvL80bRj:disqus , sorry for the late reply. It normally comes down to what your battery’s max AMP output is. Normally with high mAh battery’s you have a lower AMP output, I am guessing you have the Nitecore 18650 as there are not exactly a lot of 3200mAh battery’s on the market at the moment. Now the nitecore you have has a max AMP output of 4amps, that is not enough for vaping under 1.0 ohm. If you where to use a standard 0.5 ohm coil at 30 watts you would be using around 7.7 amps. That is already a lot more than you max 4amp output of your battery. We always recommend the Efest 18650 2800mAh 35AMP for usage on sub-ohm tanks and RDA’s. Conclusion: Do NOT use your battery for sub ohm tanks. Please read into Battery Safety & Ohms Law/a> before you jump into the sub-ohm market. It is always highly recommended to know what battery you need to use for your sub ohm tanks as this can always be dangerous if used wrongly. Have a great day and vape on!
