E-Liquids can come in a variety of ratios 50pg/50vg and High Vg 30pg/70vg are a couple of the most popular but what does it mean?
In simple terms the PG figure shows how thin a liquid is and the VG shows how thick.
Certain devices work better with certain ratios also different people have a preferred ratio It is often the case that the VG is smoother than PG.
In the main a Sub Ohm kit or Direct to Lung or more cloudy device would require a higher VG content and a Mouth to Lung would require a more balanced ratio like a 50pg/50vg This is where the term E-Liquid Ratio comes from.
