You'd be forgiven for thinking that choosing an e-juice is all about flavour and nicotine levels, but there's more to it than meets the eye. One thing newcomers to vaping often don't consider when choosing an e-juice is how it might work with their vape tank of choice. Getting your vaping setup just right takes time and patience, and there will probably be a lot of trial and error involved until you find the right experience for you, but getting your e-juice and vape tank combination right from the start will pay dividends.
Your vape tank is more important than you think
When you break a vaping device down, the basics are all essentially the same. A heating element, an atomizer and something to vape are all that's required to get started, but there are so many nuances and mods in play that you vaping experience can be hugely different from someone else's. That makes vaping a rather personal thing, and it's why many aficionados spend a lot of time tweaking and experimenting - almost like a hobby. Some vapers may want a low key vape, whereas other may want huge, dense clouds. Some might want a strong throat hit, others may want a more mellow and frequent experience - we're all different and finding that perfect balance while you're vaping feels great. One of the things that makes the experience unique is your choice of vape tank. There are countless vape tanks available, but to make things easier for yourself you could easily break them down into two main types - MTL (mouth to lung) tanks and Sub-ohm tanks
MTL (Mouth to lung) tank
Mouth to lung is a vaping technique which you can learn more about here. It's one of the most common methods of vaping and one which will come most natural to those who have experience with cigarettes. Most MTL-geared tanks are designed with in mind, using factory built coils with a more restrictive juice flow and air flow. Because they usually offer a tighter draw, those with high nicotine preferences often use this style of tank. It's also perfectly suited for thinner, PG based juices due to the somewhat restricted airflow.
If you're relatively new to vaping the term 'sub-ohm' might send you packing, but don't be intimidated. The 'ohm' is a measurement of resistance, and sub-ohming refers to vaping using a device with a resistance level lower than 1.0 ohms, as suppose to 1.5 ohm to 2.8 ohms used in regular vapes. Naturally, this impacts the vape tank. Most vape tanks geared toward sub-ohm vaping will be capable of using coils with a resistance of lower than 1.0 ohm, and they typically have much larger juice channels. Larger juice channels means more juice on the wick, which can produce huge, dense clouds (one of the perks of sub-ohm vaping for those who like to cloud chase). These tanks typically demand more power and liquid consumption.
Which juice with which vape tank?
If you imagine your vaping device as a car with modifactions, then the juice is kind of like the fuel running the show. You need to pick the right fuel for your car to ensure a good ride, and e-juice is no different. MTL vaping is generally enjoyed at a lower heat and doesn't need copius liquid flow to saturate the wick. That means a thinner juice (50% PG or higher) will deliver the best rounded experience. Using a high PG (thicker) juice in an MTL tank is doable, but not recommended as it's far too easy to end up with dry hits and scorched cotton as the viscous liquid will have a hard time finding its way through your device.
Sub-ohm tanks on the other hand are far better with thick, heavy liquids. Because it's all about big hits and even bigger vapour production, sub-ohm vaping requires a lot more heat and wider juice channels to get more on the wick. For this, a high PG juice is perfect as it will withstand the heat and be able to move freely through larger juice channels.
At the end of the day, your setup is your choice, and you may find a configuration that other people don't quite understand. However, there are general guidelines like those mentioned above that can seriously help you on your journey.
