VAPORIZERS – ACCESSORIES – GRINDERS A good grinder is a key to the effective vaporising. After all, you want to make the most of your vaporiser, don't you? Make sure you buy a grinder that crushes the herbs into fine pieces. This will guarantee that your herbs are perfectly ground and that it is easier for the heat to penetrate them. The closer the herbs get to the consistency of powder, the easier it will be for the vaporiser to get your favourite substances out of them. You just cannot underestimate it – a good grinder is half of success.
