Tips & Guides

Sub-ohm vaping is a vaping practice using electronic cigarettes with resistances below 1 ohm (Ω). This style of vaping is popular for its ability to produce dense vapour, intense flavours and pleasant throat sensations. Here is a detailed overview of sub-ohm vaping, its benefits, its drawbacks and the precautions to take.

Understand sub-ohm vaping
- Definition: Sub-ohm refers to the use of resistances with a value below 1 Ω. These resistances allow more current to pass, heating the e-liquid faster and at higher temperatures.
- Hardware: Sub-ohm devices include sub-ohm tanks, rebuildable dripping atomisers (RDA) and rebuildable tank atomisers (RTA). They are often used with powerful box mods.

Benefits of sub-ohm vaping
1. Dense vapour: Sub-ohm resistances produce abundant and dense vapour, ideal for cloud-chasers.
2. Intense flavours: Higher temperatures release flavours more intensely, providing a tastier vaping experience.
3. Smooth throat sensation: Compared to MTL (mouth-to-lung) vaping, sub-ohm vaping provides a softer throat sensation, while delivering a satisfying "throat hit".
4. Direct inhalation: Suited to direct-to-lung (DTL) inhalation, similar to a deep breath, providing a more powerful experience.

Drawbacks of sub-ohm vaping
1. Increased liquid consumption: Sub-ohm devices use more e-liquid due to the increased production of vapour.
2. Battery consumption: Higher temperatures and currents require more powerful and durable batteries.
3. Cost: Sub-ohm devices and accessories can be more expensive than standard hardware.
4. Less suitable for nicotine: High-PG e-liquids and higher nicotine levels can be unpleasant in sub-ohm vaping due to the strong throat hit. High-VG e-liquids and low nicotine levels are usually preferred.

Components of sub-ohm vaping
1. Sub-ohm tanks: They have replaceable resistances under 1 Ω. They are easy to use and maintain.
2. Rebuildable Dripping Atomisers (RDA): These atomisers require frequent application of e-liquid directly to the cotton. They offer great flexibility for vape enthusiasts.
3. Rebuildable Tank Atomisers (RTA): They combine the benefits of sub-ohm tanks and RDAs by allowing user-mounted resistances while having a tank to hold e-liquid.
4. Box Mods: Powerful and customisable devices that can deliver the energy needed for sub-ohm vaping. They have features such as wattage and temperature adjustment, as well as removable batteries.

Safety and best practices
1. Battery safety: Use high-quality batteries suited for sub-ohm vaping. Make sure they are in good condition and that the device's contacts are clean.
2. Choice of resistances: Use resistances from reputable brands. Check the resistance and condition of the wires before each use.
3. Building and maintenance: For experienced users using RDAs and RTAs, make sure the resistances are well built and securely mounted. Replace cotton regularly to avoid bad tastes.
4. Compatible e-liquid: Use high-VG e-liquids (30/70 or 20/80) for an optimal sub-ohm vaping experience. Avoid high nicotine levels to prevent unpleasant sensations.
5. Power and ohms: Adjust your device's power according to the resistance used. Stay within the manufacturer's recommendations to avoid damage and risks.

Conclusion
Sub-ohm vaping is a great option for those looking for a more intense vaping experience, with dense vapour and pronounced flavours. However, it requires good knowledge of the hardware and adapted safety practices. By choosing the right e-liquids, adjusting your device correctly and using quality batteries, you can fully enjoy sub-ohm vaping. Whether you are a beginner or an experienced vaper, take the time to learn about the specifics of this practice to ensure a safe and pleasant vape. Happy vaping!
