- PG (Propylene Glycol) is a thin, tasteless liquid that increases throat hit and allows for more flavor to come through in the vape. Due to its properties, more often than not it will be a main flavor "carrier" in the liquid you purchase to vape.
- VG (Vegetable Glycerin) is a thicker, sweeter liquid that increases vapor density (cloud production), has no throat hit, and typically will dilute the overall flavor that you get.
There are many pro's and con's for each individual blend of e-liquid that you may find on our site or other sites in general. The usefulness of each blend, however, will be greatly determined by the setup that you are currently using.
If you are prone to using "Mouth To Lung" setups that frequent higher ohm coils with smaller wicking holes you are going to benefit more from a higher PG blend (and depending on your preference a higher nicotine level as well). Due to the smaller wicking holes, you are going to want a thinner liquid that will be able to make its way to the cotton and be vaporized completely. Higher VG blends will have a tendency to clog these holes and cause the coil to give off burnt hits- essentially ruining the vape you are getting.
On the other hand, if you are in the realm of "Sub-Ohming" and are using tanks/RDA's that rely on lower ohm coils with larger wicking holes (which generally will also use much higher wattage levels) you will want to be in an opposite range. Due to the higher amounts of heat/power being pushed into these coils along with more space for the liquid to run through; a sub-ohming vaper will benefit greatly from a higher VG based liquid to ensure that both the coil is wicking properly and that the chance of leakage happening is cut down significantly.
- Going hand in hand with these sub-ohm tanks is the need to save your throat. With larger and more concentrated amounts of vapor being produced at hotter temperatures- higher PG based liquids will tend to cause a very harsh vape that will not be too enjoyable regardless of the elevated flavor that you may be getting. In order to combat this, higher VG blends (typically at a 50/50 or well above) are going to be a sub-ohm vapers best friend.
While these recommendations are basic and provide a good structure for getting your overall setup and e-liquid selected initially, vaping is all about customization. Everyone will have different preferences and it is more than possible that what works for someone will not work for another; or that one may enjoy a different type of blend in their sub-ohm tank apart from what was recommended here. That is completely okay. One should never feel obligated to conform to a specific blend based solely on the recommendations of another vaper but should feel free to experiment and find what works for them to keep them vaping happily. Hopefully this will still provide a good starting point for you in your vaping journey!
