VG and PG in Vaping: What You Need to Know

If you’ve been around vaping for a while, you’ve probably seen the terms VG and PG on e-liquid bottles or device descriptions. They might look a little confusing at first, but don’t worry — they’re just the two main ingredients that make up almost every vape juice out there. Let’s break them down and see why they matter.

VG: Vegetable Glycerin

VG (Vegetable Glycerin) is a plant-based liquid that’s thick and a little sweet. In vaping, VG is what gives you those big, fluffy clouds and a smooth inhale.

• It’s thicker than PG, so it works best in bigger devices.

• If you’re into cloud chasing, you’ll want a higher VG blend.

• It smooths out the throat hit, making each puff easier on the lungs.

 Think of VG as the “cloud maker.”

PG: Propylene Glycol

PG (Propylene Glycol) is the opposite — it’s thin, flavorless, and not sweet at all. But don’t underestimate it — PG is what carries the flavor and gives you that sharp throat hit a lot of ex-smokers look for.

• It’s runnier than VG, so it soaks into wicks and coils easily.

• It makes flavors pop more.

• It delivers that stronger, cigarette-like throat hit.

PG is the “flavor booster.”

VG vs. PG – The Balance

Most e-liquids are a mix of VG and PG. A 70/30 blend (VG/PG) is common for smooth clouds, while a 50/50 blend gives you a stronger flavor and sharper hit. It’s all about what you prefer — smoother and cloudier, or sharper and more flavorful.

What VG/PG Ratio Should I Use?

There isn’t a one-size-fits-all answer — it really depends on the kind of vaping experience you’re after. Here are a few common scenarios:

Throat Hit – If you enjoy a sharp, cigarette-like hit, go with a higher PG vape. Many ex-smokers prefer this, since PG (along with nicotine) gives more of that “kick” at the back of the throat. PG also carries flavor a bit better, so the taste may feel more pronounced.

Smoothness – If you prefer a smoother draw, a higher VG fluid is the way to go. It gives a thicker mouthfeel and softer hit, though the flavor can be slightly muted. You can make up for this by using more power to produce more vapor — just be mindful not to exceed your device’s wattage limits.

Stealth Vaping – Want to keep it lowkey? High PG produces less visible vapor, making it better for discrete use. That said, always follow local rules and common courtesy — vaping in waiting rooms, on public transport, or in other restricted areas isn’t appropriate.

Cloudchasing – If your goal is massive clouds (some people even compete in it), then you’ll want high VG — the higher, the better. VG is what fuels those dense, show-stopping clouds.

Why It Matters for Devices

Not every vape device works with every liquid. High-VG juices are thicker, so they need more power and cotton wicking to vaporize properly. High-PG juices are thinner and work better in smaller coils.

That’s why we designed our new Rocket device specifically with a cotton core for VG/PG liquids. It’s different from our cannabis-focused hardware — built for nicotine-style vaping, with a huge 14ml tank, 650mAh rechargeable battery, and a large digital screen that shows puff count and battery life.
