If you're a real cloud chaser using a sub-ohm device, you've figured out by now that the bigger the clouds, the more e-liquid you go through. If you're looking for a cheaper alternative than the ready-to-use 10ml bottles, making your own e-liquid is a good option. It may seem intimidating at first, but if you can mix a cocktail you can make your own e-liquid. It's all about finding the right balance, and of course, personal preference.
