Use coconut coals whenever possible. A half kilo of coals cost under $6 and will supply you for at least 12 smoke sessions.
Most serious smokers and premium hookah lounges today use coconut coals. They take longer to light, about 10 minutes, but they last much longer than other coal options and have a cleaner taste. Easy Light and Quick Light coals have a place in the market for those who require coals to be lit quickly (perhaps you’re running home to make a hookah during your work break) or those who are outdoors and don’t have a proper heat source for starting up coconut coals. It’s extremely simple to ignite Easy or Quick Lights with any lighter and they are fully lit in just a few minutes but you need an electric burner or grill fire to start a coconut coal.
You don’t have to worry at first if your coconut coals are a flat- or cube-style and if they are 22mm cubes or 25mm cubes. They all work and will get your bowl smoking for a long time. With more experience in heat management, you’ll learn which coconut coal style and size best suits your heat preferences.
