Sometimes buds can be extremely dense or sticky and it can be hard to crush weed for rolling. This is where a weed grinder comes in handy. Whether the bud is compacted regs or the stickiest of green, a grinder always transforms them into perfect form for rolling joints, blunts or packing bowls. Using a grinder will save you lots of time and it optimizes the way weed burns so that you always get great hits. Most grinders, like the 4 piece grinders featured here, also collect the pollen crystals, or kief, that fall off the buds when grinding and over time you'll have a really nice treat.
