How to Use a Herb Grinder for Cannabis

Break your flower into pea-sized pieces, load them into the top chamber, close the lid, and twist three to five full turns in one direction. Unscrew the middle section and tip the ground cannabis onto your tray. A grinder turns a single bud into pieces of the same size, which helps the flower burn or vaporize with less waste and a smoother pull.

What You Need

• A clean herb grinder (two-piece, three-piece, or four-piece)
• Dried and cured cannabis flower
• A rolling tray or clean flat surface
• Isopropyl alcohol and a small brush for maintenance

Step-by-Step

1. Pull any stems and seeds out of the bud with your fingers.
2. Break the flower into pieces about the size of a pea.
3. Open the top chamber and drop the pieces inside.
4. Fill the chamber about halfway. A packed grinder jams and tears the flower instead of cutting it.
5. Set the lid back on and turn it in one direction with firm pressure.
6. Count three to five full turns, then stop.
7. Open the lid and check the texture. Large chunks need another two turns.
8. Unscrew the middle section and pour the ground flower onto your tray.
9. Tap the bottom chamber over your tray to release the kief that fell through the screen.
10. Close the grinder and store it somewhere dry until the next session.

Pick the Right Grind Size

• Fine: rolling papers and most vaporizers. Burns faster and hits harder.
• Medium: pipes, bongs, and one-hitters. Keeps airflow open.
• Coarse: large bowls and blunts, where you want the material to breathe.

Turn the grinder fewer times for a coarse grind and more times for a fine one. The same flower gives you either result, so match the texture to how you plan to consume it.

Clean Your Grinder

1. Take the grinder apart into its separate pieces.
2. Scrape stuck plant material off the teeth with a brush or a plastic card. Metal tools scratch the coating.
3. Soak the metal parts in isopropyl alcohol for 20 to 30 minutes.
4. Wipe plastic and acrylic parts with a cloth dipped in alcohol instead of soaking them.
5. Rinse every piece with warm water.
6. Let the parts dry on a towel before you put the grinder back together.

A gummy grinder smears flower instead of cutting it. Clean it once a month if you grind daily, or sooner if the lid starts to stick.

Common Mistakes

• Loading whole buds, which stalls the teeth.
• Filling past the halfway mark.
• Twisting back and forth, which crushes instead of cuts.
• Throwing out the kief in the bottom chamber.
• Grinding flower that is too moist. Let damp buds dry for a day first.
