For a more smooth and flavorful vapor try using a temperature range of 180 – 200° Celsius (356 – 392° Fahrenheit). For a stronger and thicker vapor try using a temperature range of 200 – 220° Celsius (392 – 428° Fahrenheit). Also keep in mind that different temperatures are required for different herbal blends, so you may need to adjust the temperature to achieve the same result with the different types and qualities of herbs that you use.
