Grinding dry herbs for vaping is a must. No matter what vaporizer you get yourself you should also avail yourself of a good grinder. Grinders keep your dry herb fine and vaporizers will always work much better with a finer than coarse herb. Also using one will help you conserve your herbs by giving you those more consistent textures. It helps increase surface area ensuring you are having minimal wastage and take in as much vape as possible.
