A 2026 sub-ohm e-cig setups guide for DMT e-juice vape

[The Sofa Traveler]

I need a Tiny Cork!

Yeah that would be cute I thought a 3D printer could be nice to built the perfect suitable cork.

one could store the entire vape in a sealed container too like a ziplock baggy or a large jar

Also @The Sofa Traveler so 1g DMT per 2ml of juice is a standard ratio, should we double this ratio to 2g DMT per 2ml? or more than that? Im new to vaping so I want to learn tips/tricks & to get dosing down

Yes, but at the very least, the jar or the bag should be vacuum-sealed otherwise the oxygen that is in would oxidize the juice. Of course, your proposition could be combined with mine or can be an alternative possibility for someone who doesn't have cellophane or a suitable cork but it wouldn't be a convenient method for someone like me always switching tanks and mods both for DMT and nicotine, because I'd have to vacuum-seal the bag or jar again each time I want to use the mod on which the DMT tank is.
1g/2ml is very potent with a sub-ohm tank but potency will also depend on the tank model and the coils used. Lower impedance coils will have a larger heating surface, thus delivering more aerosol. So for 1g/2ml, potency might vary depending on whether you use 0.15Ω or 0.4Ω coils but roughly speaking 1g/2ml is rather on the strong side but still offers room for intermediate doses, especially with coils on the higher ohm value end. 2g/2ml - in other words 1g/1ml ratio - might be a little too strong, unless your goal is to chase a one-puff-breakthrough and nothing else but the risk of blacking out will be increased as well. And it would be rather difficult to navigate intermediate doses with such a ratio usually intended for weak delivery systems like carts. With a decent sub-ohm tank and 0.15Ω coils you'll definitely won't need such concentrated juice if you want to blast-off. Overall, there are many possibilities to dial your device and juice according to your needs, by tweaking juice ratio, by tank and coils choice, by power settings, by inhalation tension/pace. It might take time to find your sweet spot, or you might be lucky and find it from the first try.

Thank you so much for the guidance @The Sofa Traveler Im sticking with 1g per 2ml

I tried to vape deems with Legend 5 + Fli 2 tank, 0.15ohm, at 15Watts , only could find 5ml tank. EU vape suppliers seem to only ship TPD-compliant 2ml tank locally, not internationally, so after filling the 5ml tank with e-liquid, it was so harsh, the atomizer got so hot, perhaps due leaking under the base, how do you handle the harshness, and the leaking? Would using fumarate or other salts mitigate the harshness or should I stick to freebase?

Something probably went wrong because 15w with a 0.15Ω coil is very low power wise. Such coil should work fine in the 25-30 watts range. Leaking shouldn't happen neither except in very isolated cases. Tank shouldn't get so hot, especially at 15w.

• Maybe there was a short-circuit due to juice leaking in the bottom cap.
• Maybe the coil or the tank was defective.
• Maybe coil was not well inserted.
• Maybe an O-ring from the tank or the coil is missing.
• Normal mode (= standard watts mode) from the Legend 5 is the one you should use.

I think @TransistorBass is using the same tank and didn't report such problems. Maybe he could help. I've used the Zeus tank sporadically some years ago and didn't encounter such problems neither. That said it happened once I had a defective coil.
Which amount of juice did you have ? Wick of the coil might not be soaked enough if you used very low amount of juice in a 5ml tank. Also, at very first use you should always let the wick soak for 30/60mn to ensure wick is properly soaked.
If you want to use a salt form of DMT, use DMT citrate, don't use fumarate. But honestly, I don't think the harshness problem comes from there. Freebase shouldn't be harsh at all when vaped at reasonable temperature range (so 25-30w for the 0.15Ω coil). I'd suggest to check the coil and tank first before considering using a salt form, because if the problem comes from there, DMT salts won't change anything.
If you're in EU maybe you can get your hands on the BD Vape Precisio Sub-ohm Blaster Edition V1, it is provided with 2ml straight glass as well as 4.5ml bulb glass. Definitely my fav sub-ohm tank. I use it for deemz as well as daily for nicotine and never encountered any problem of leaks, harshness or whatever. The build quality is a cut above.

Going above 15W made the vapor super harsh It made me cough immediately after 1 second toke so I stayed at 15W.

"Maybe there was a short-circuit due to juice leaking in the bottom cap."

Indeed the bottom cap was full of juice, causing a short circuit which in turn was causing overheating, don't know why this happens even on my Zeus subohm tank 2021 model that originally came with my Legend 5 which I use for nicotine salts.

"Maybe the coil or the tank was defective.
Maybe coil was not well inserted.
Maybe an O-ring from the tank or the coil is missing."

It was brand new, freshly unboxed and never ever used for anything before, I bought it specifically to try DMT e-juice.

"Which amount of juice did you have ? Wick of the coil might not be soaked enough if you used very low amount of juice in a 5ml tank. Also, at very first use you should always let the wick soak for 30/60mn before first use to ensure wick is properly soaked."

I used 4ml juice, left it to soak for 10 mins, not 30/60 mins.

"If you want to use a salt form of DMT, use DMT citrate, don't use fumarate."

I'm afraid of citrate decomposing to toxic compounds, and the citric acid attacking the metals in the tank, but I will try it with low-wattage to see if it will smooth things out hopefully! Have you tried Acetate, Fumarate, Benzoate, Malate and other salts or is Citrate simply the go-to salt for some reason?

Unfortunately I'm not in EU, so I can't get TPD-compliant 2ml tanks and will have to use 5ml tanks for now.

I don't know why it went wrong but your problem probably comes from there. There was a time when Zeus tanks, especially Z Series coils, were reported having poor QC (I experienced it once as mentioned above). I don't know if it's still the case nowadays. I don't use anymore my Zeus Sub-ohm neither my Z Max, never enjoyed them much. Less reliable knock-off material (coils as well as tanks) is also on the market, check authenticity.
Nicotine salts are not intended to be used with sub-ohm tanks, they are rather intended for MTL tanks or carts. As they are stronger and have better lungs absorption, it is not advised to use them in high aerosol delivery systems.
Also, nic salts juices most of the time are 100% PG, which makes them very runny for sub-ohm tanks (although it shouldn't leak as hell to the point of filling the bottom cap).

I used 4ml juice, left it to soak for 10 mins, not 30/60 mins.

That's a little short in time but your tank was quite well filled so I don't think the problem is here. What was your juice ratio ? Did you use straight PG or PG/VG mix ?

That's legit concern. I've used the citrate but over time I didn't find it reliable and it was quite sensitive to overheating compared to freebase. Freebase is not harsh when used in adequate temp range. Iirc, citrate was the favored salt because it's the one with the least toxic compounds decomposing profile. If your tank is overheating for some reason, harshness would be even worse with a citrate juice.

That said, I don't think your harshness problem comes from freebase, it seems to be an overheating problem. That's why I suggest to address the leaking, O-rings, tank and coils check first. Start with new coil anyway.

Ultimately, I'd advise to get your hands on another tank model/brand if you can. There is a tank list in the initial post from this thread. If you have in mind a model that is not in the list and are unsure let me know. Which country are you in ? (if you don't mind to answer of course)

 

[TransistorBass]

I think you guys covered everything and more than I could.
I’ve mostly given my new coils a 20+ minute soak before trying to Fire the vape and always been fine. I do notice that that if the vape is held at an angle and it uncovered the juice holes that feed the coil it can give a dry hit of burnt cotton. 30-35watt is where I’m running them at 20-25watt was too much gurgling and not enough vapour.

 

[HumanOcean]

What was your juice ratio ? Did you use straight PG or PG/VG mix ?

1:4, I used 2ml PG, 2ml VG, with 1g DMT

I'm thinking of getting an RDA tank, I read they're less prone to leaking, not sure which brand I should get as I've just started to explore vaping nicotine (and DMT) about a week ago. As for the country, I'd rather say it in a PM/DM instead, but it's an African "French protectorate" lol

I noticed the gurgling which might spit some lips-numbing ejuice at low watts too, but at higher wattages, specifically 20W seems to remedy that, also angle-vaping indeed won't let the cotton absorb properly

So straight PG if I understand well. Sub-ohm tanks are not very optimal with 100% PG, some VG could have been added to the mix. A 1g/4ml or 1g/3ml juice ratio can easily handle 50PG/50VG without re-crystallization. I think 20-30% VG should be minimal amount for such juice in a sub-ohm tank with a 0.15 coil. 100% PG juices are usually used with carts.

That's another option but it's less straightforward, you might experience hits & misses to build the coil with the proper cotton amount before achieving conclusive results. Especially if you're an absolute beginner in vape world (if you are). But once all is well mounted and set it works pretty fine indeed.
No prob for the country, I was just asking to evaluate the e-cig market to which you have access to.

Sorry I made a typing mistake, it's 2ml PG + 2ml VG

That's also what the vape shop told me about RDAs, gotta expect hits & misses, so I opted for regular non-rebuildable Fli 2 tank instead.

This should defo be fine with a sub-ohm tank then.

Try to check all aspects of the tank and coil as aforementioned. Maybe ask the shop where you bought it some help. Ask if there are other models than the Zeus Sub-ohm, like the Zeus Nano if they only have Geekvape stuff. I've had pretty great results with the Z Nano without problems. The B Series 0.2 coil should be fine with the juice you already made. Also, if you have full access to French e-cig market, the BD Vape Precisio Sub-ohm Blaster Edition should be easy to grab.

 

[HumanOcean]

It worked now, I reduced Deems concentration, cleaned the joints and it's no longer leaking and harsh! Very nice!

 

[Evanesce]

I just got a Geek Vape Zeus Z NANO 2 Tank. I mixed up 0.7ml PG 0,3 Ml VG with 300Mg DMT. I put some juice directly onto the coil, filled the tank and let it sit overnight before use. Using the 0.2ohm B Coil from 15-25 watts. About 2-3 hits and I feel a very deep relaxation. Jello body. I yawn and another hit makes me want to pass out. Zero visuals - no trip. I have tried slow and medium rate tokes at 15, 20 and 25 watts. Still no visuals. I load up the Youcan Orbit with about 20Mg take 2 hits and I am off. Good visuals and experience. What can I do to the Zeus to trip? Would getting the 0.3 ohm coil do it?
