When it comes to using a grinder or hand crumbled, if available always use a grinder and ensure that the grinder is clean. Using a grinder will allow your fresh herbs to be ground up evenly to ensure a more fluid burn. When using a grinder, you ensure the consistency needed to break down each bud and saving as many trichomes to be consumed, plus nothing is wasted on fingers and thumbs (as with hand-crumbled).
