Vegetable glycerin (thicker, more vapor) and propylene glycol (thinner, more throat hit / flavor carry). Ratios like 70/30 are common on open systems.
Higher VG can wick slower in small pods. Match ratio to device guidance before you blame a coil for dry hits.

VG / PG questions
What VG/PG ratio is best for pods?
Follow the device insert — many pods prefer 50/50 or 60/40. High VG can wick slowly in small pods and cause dry hits.
Does flavor count as PG in mixing?
In simple DIY math, flavor volume is often treated as PG. The e-liquid mix calculator on WINDBAR follows that convention.
