2 ohm vs 3 ohm atomizer, which one should I use in my lavatube and why

[waynebrady]

It is my intention to create an awesome vaping experience for myself. With that in mind, I just purchased a lavatube variable voltage battery as an upgrade from my not-even-a-week-old eGo-C. I've been googling and lurking this forum for ideas and tips so I think I have a good idea of a nice budget setup.

Here would be the setup so far:

Lavatube from Apollo -Apollo VTube
Boge 2 or Boge 3 cartomizer with momandpops mini-sub tank - Tanks - Mom and Pop Vapor Shop100% VG juice, 0mg, from popular vendor - Organic Kona Coffee Milkshake E-liquid | Virgin Vapor | Electronic Cigarette Organic e-Liquid | Electronic Cigarettes
Reasoning:

Lavatube because it's cheap and has a year long warranty. I know the batteries are going to be a big question mark so I'll get AW versions of that eventually.

100% VG juice because I read that you get the most vapor from VG juice. I like vapor. Lots and lots of vapor. And I heard that the flavor is just fine in general. I read that VG juice is really thick though and that the thickness of the fluid might be a concern when it comes to pick out a particular atomizer.

Boge 2 or Boge 3? I really only selected the momandpop mini-sub because other folks on the forum mentioned it. The side entry on the tank looks like a good idea as well. The only concern I have with this vendor is that I read they poke three holes in the cartomizers they ship with the setup. Sometimes this causes the setup to flood really easily and ruin your cartomizer. I'm not exactly sure if "ruin" means that you can't use it anymore or if it means that you just have a lot of cleaning or maintenance to do.

Ok all the concerns so far have only been minor, not very important, concerns. My more important concern is the OHMS!

With a lavatube and a 2 ohm atomizer, my rig could reach up to 12 watts in power. With a 3 ohm atomizer I can only reach up to 10 watts of power.

But, with all the things I've mentioned so far like 100% VG, how do I know which ohm size is right for me? What factors am I not considering? I need some guidance or some clue to help me pick the 2 ohm or the 3 ohm.

Which one will last longer with my VG juice?
Should I care about maxing out at 12 watts or is 10 watts fine?
Do either of the two have an advantage when it comes to vapor output or even flavor?
Why 3 ohm? Why 2 ohm?

Help?

I would go with the Boge 2.0

The reason is either the 2.0 or the 3.0 will work fine on a VVPV like the Lavatube. But the Boge 2.0 will also work with your eGo.

Whereas the Boge 3.0 probably will not give you much of a hit on an eGo.

It works like this:

The more power a battery sends to the coil the more juice that can be vaporized.
power = watts
More volts = more watts = more hit, vapor and flavor.
Lower ohms = more watts = more hit and vapor and flavor.

With the same voltage you will get a lot more hit and smoke with a 2.0 ohm cartomizer than with a 3.0 ohm cartomizer. Low ohm cartos also need to wick fast enough to keep up with the larger amount of juice being vaporized. So you are more likely to get a burnt taste.

Using more watts will also drain your battery faster.

You can also thin vg with Ethel alcohol or even water. I use everclear but vodka will work if that's not available.

I use 3ohm Boge cartos on mine at 6v and am happy with it.

100% VG juice is kind of thick for cartos though. It doesn't wick well and you have to worry about burning them. It's ok if you just take a puff every few minutes, but if you chain vape (like me), it just doesn't cut it.

I doubt you'll notice too much of a difference between 10 and 12 watts (I don't). If I really want some hot vapor I run my Roughstack at around 24 watts. I like only having to take a 1-2 second drag instead of my normal 6-7 second ones when it's setup like that.

Should I really consider rig inter-comaptibility? I didn't even factor that into my decision making process. Seems like low fruit at this point. But, I suppose it's better to be able to switch around parts with my current setup if I want than to be restricted to just rigid systems. Thanks for the input.

Low ohm cartos also need to wick fast enough to keep up with the larger amount of juice being vaporized. So you are more likely to get a burnt taste.

In that case, what would be the best atomizer setup for 100% VG? I want the most vapor I can get, without the burnt taste.

I chain vape. Is there no option for a chain vaper to use 100% VG? If not carto's, then what should I use to pull this off?

And if it's just not possible, then what VG/PG ratio is best for the most vape without the burnt taste?

Phil Busardo has a great review of the L-Rider VV device. It may help you with your cartomizer question. After watching it I went with the Boge 3.0ohm cartos for mine. pbusardo's Channel - YouTube

I watched that twice yesterday. But he doesn't cover juice at all. From that video I still can't tell what setup to use for 100% VG.

+1 on the Boge 3 ohm works great on the LT

 

[GhosT81]

If you plan on running 5-6v I would do 3ohm

 

[GhosT81]

Check out an io6 atty from ikenvape.com. get a 3.5 ohm since they don't have a 3

Heat (watts) = Voltage squared divided by ohms (resistance).... (V*V)/R. You have a vv device. Memorize this equation. You can also use an ohm's law calculator if you wish: Ohm's Law Calculator

Once you know your target wattage, you can adjust your vv device's voltage for whatever ohm rating you have. That said, I find the higher ohm stuff more robust for atomizers. Probably true for cartos too. However, if you ask 100 people to give you opinions on cartos, you'll get 100 answers. So some of this is trial and error and your personal preference. Different designs will be different. You have to try em.

Of course, like zoiDman said.. you may wish to consider cross-device compatibility.

Note: The LT has a 2.5 amp limit (use the calculator to check).

No Problem.

I don't like to have to buy One Type of Carto for this PV and One Type for that one. I just want to reach for a Carto and use it on whatever I choose.

You might find that the LT isn't the Greatest Device to carry around with you. It doesn't fit well in a Shirt Pocket or Purse. Whereas an eGo is a nice size when you want to run down to the Store for a Quick Trip. So buying Cartos that work on Both makes sense to me.

If I was you, I'd buy a pack of each of the 2.0 and 3.0. Cartos are Cheap. Then do you own testing and see what works best for you and your e-Liquids.

I use ethyl alcohol thin my vg juice. Everclear has the highest proof but vodka also works. Even distilled water helps. Start at about one percent and if that isn't enough for the cartos you use add more.

Find the watts you like best on your lava tube then get a carto or atomizer that will give the same wattage with you other battery. Now you can use that cartomizer on both by setting the voltage on the lavatube to get the same watts.

I ended up doing this. Got the mini-sub 2ohm and 3ohm carto's + tanks. Should be in sometime this week. I'm direct dripping until then.

Thanks guys for all the help.
