Low Temp dabs, in my opinion are one of the best ways to consume wax. Keeping the temperature between 350f and 450f will help to produce a smoother, more flavorful pull, which is better on the lungs. It also preserves the flavor.
Concentrate is not only high in THC is also has amazing terpene and cannabinoid profiles which attribute to the flavor & effects. Taking a dab at a high temp will destroy not only the flavor profile but it will also burn off some of the THC.
Electronic Rigs (like puffco) have pre-determined temp settings! I suggest to follow the directions that came with the device came with.
How do I know if the temp is between 350 and 450? Is there an easy way of doing this?
