70/30 on vape juice refers to the ratio of two primary ingredients: 70% Vegetable Glycerin (VG) and 30% Propylene Glycol (PG). This ratio is a key indicator of how the e-liquid will perform, influencing everything from vapor production to throat hit and flavor delivery.
Understanding VG and PG
To fully grasp what 70/30 means, it's essential to understand the roles of Vegetable Glycerin (VG) and Propylene Glycol (PG) in vape juice. These two components are fundamental to the vaping experience.
- Vegetable Glycerin (VG): A thick, slightly sweet, plant-based liquid. It is responsible for producing the large, dense clouds of vapor associated with vaping. High VG e-liquids tend to be smoother on the throat.
- Propylene Glycol (PG): A thinner, odorless liquid. PG is known for carrying flavors more effectively and providing a stronger "throat hit," which simulates the sensation of smoking traditional cigarettes.
Characteristics of 70/30 Vape Juice
A 70/30 VG/PG e-liquid is characterized by its high VG content, making it thicker and ideal for producing large vape clouds. This ratio delivers a distinct vaping experience tailored for specific preferences and devices.
- Cloud Production: With 70% VG, this type of e-liquid excels at creating substantial and dense vapor clouds, making it a favorite among cloud chasers.
- Throat Hit: The higher VG content provides a smoother, less harsh throat hit compared to e-liquids with a higher PG ratio. This can be more comfortable for vapers who prefer a gentler sensation.
- Flavor Intensity: While PG is better at carrying flavor, 70/30 still offers good flavor delivery. However, the flavors might be slightly more subdued or "mellowed out" compared to a 50/50 blend due to the lower PG percentage.
- Consistency: The higher VG makes the e-liquid noticeably thicker. This thickness impacts its suitability for different vaping devices.
VG vs. PG: A Quick Comparison
| Feature | Vegetable Glycerin (VG) | Propylene Glycol (PG) |
|---|---|---|
| Consistency | Thick, viscous | Thin, runny |
| Vapor Production | Large, dense clouds | Less vapor, smaller clouds |
| Throat Hit | Smooth, gentle | Stronger, more pronounced |
| Flavor Carrier | Slightly sweet, can mute flavors | Excellent, sharp flavor delivery |
| Primary Use | Cloud chasing, smoother vape | Strong throat hit, intense flavor |
Ideal Usage for 70/30 E-Liquids
Due to its specific characteristics, 70/30 vape juice is best suited for certain vaping styles and devices:
- Sub-Ohm Vaping: This ratio is highly recommended for sub-ohm tanks, rebuildable atomizers (RDAs), and other high-wattage devices designed to produce large vapor volumes. These devices have larger wicking ports capable of handling the thicker liquid.
- Direct-to-Lung (DTL) Vaping: 70/30 is excellent for DTL vaping, where vapor is inhaled directly into the lungs, mimicking the sensation of breathing rather than sipping.
- Vapers Seeking Large Clouds: If your primary goal is to produce impressive vapor clouds, 70/30 is an ideal choice.
Considerations When Using 70/30 Vape Juice
- Coil Life: Thicker e-liquids can sometimes wick more slowly, potentially leading to dry hits or faster coil degradation if your coil isn't designed for high VG.
- Device Compatibility: Avoid using 70/30 e-liquids in smaller pod systems, vape pens, or mouth-to-lung (MTL) devices, as their coils and wicking ports are often too small to handle the thick liquid, leading to poor wicking and dry hits.
In summary, 70/30 vape juice is formulated for vapers who prioritize substantial vapor production and a smooth throat hit, typically using more powerful vaping devices.
