The Complete Guide to Cannabis Grinders

The purpose of a grinder is to shred and cut the cannabis into smaller particles. This process makes it easier to smoke marijuana. It also increases the surface area of the plant matter, which ensures better flavor. This guide looks at how a cannabis grinder functions, the different types, and outlines how to clean one.

How Does a Cannabis Grinder Work?

The best grinders make it easy to shred marijuana buds. Doing this makes it simpler to pack a bowl or roll a joint. It also provides a smoother smoking experience. You don’t necessarily need a grinder. You can use your hands, keys & cards, scissors, a coffee grinder, or other household items. However, a grinder does a far better job.

It is a tool specifically designed to grind cannabis. It should also have ‘extras’ such as a handy kief catcher that gathers the potent crystals knocked off the plant material when you grind it. You can use kief to increase the THC content of a joint or bowl.

Why Not Buy Pre-Ground Cannabis?

It is unwise to buy pre-ground herbs because dried buds become stale over time. If you see already ground bud, there’s a good chance it has already lost much of its flavor. To get the best out of your cannabis, you need to keep the buds intact until it is time to use them. This is where a grinder comes in useful.

Type of Cannabis Grinder

In general, you’ll find four types of cannabis grinder available for commercial sale. The following relates to hand grinders capable of handling a few grams at a time.

Two-Piece Single-Chamber Grinder

This is the grinder of choice for marijuana users on a budget. It is a basic design with both parts containing sharp teeth. Using it is very easy. Place your buds in one part, close the two pieces together and start rotating. These grinders have no kief catcher, and the crystals usually get stuck to the chamber’s sides. Typically, these items are made from metal, plastic, or wood.

Four-Piece Three-Chambers Grinder

This is the cannabis grinder best suited to regular users. Each of the three chambers has a specific function:

  • One for the bud you want to grind
  • One for the bud you’ve already ground
  • One for catching kief

Using this one is slightly more complicated but is still fairly easy.

  • Remove the top lid and add the buds to the chamber designed for grinding. It is helpful to use your hands to reduce the size of the buds. Avoid putting anything in the middle, as this is where the grinder’s magnet turns. As a result, buds you place in this area don’t get shredded.
  • Put the lid back on and rotate the grinder. Keep rotating it for as long as it takes for all of the plant material to fall through the holes. Remove the lid and tap it against the grinder’s side to loosen the bud stuck in the teeth.
  • Unscrew the chamber that holds the ground bud, and you’ll see the fruits of your labor. Load the bud into a bowl or joint and enjoy the experience.
  • You should also check the kief chamber regularly to see if there is enough to add to a joint or bowl.

Electric Grinder

These are quite expensive but provide you with an immense level of convenience. It is best to find a battery-powered one. Otherwise, you’ll need to find a power outlet for a plug. The other downside with electric grinders is that they can demolish your cannabis. In general, you should only use one of these devices if you need to grind a large amount of marijuana in a short timeframe.

Card Grinder

This is the least popular option, and you won’t find much of a difference between the top brands. Advantages of card grinders include low cost as well as being easy to store and carry. The design is very basic: A metal card with numerous small holes for grinding. They look like food graters but using one typically results in a mess.

How to Clean a Cannabis Grinder

There will come a time when you have to give your grinder a deep clean. Incidentally, make sure you clean it thoroughly when you first buy it. The shipping process could leave residues that you don’t want in your cannabis. In an ideal world, you’ll clean your grinder after every single use. This ensures that you’re not mixing old buds with new plant material.

If you don’t clean your grinder for a while, you’ll eventually notice a resin build-up. It will cause the threading on the sides where you screw the pieces together to get sticky. This means you won’t be able to twist them. If this happens, here’s what to do:

  • Use salt and isopropyl alcohol on the stickiest parts.
  • Knock the kief loose with a small brush.
  • Consider freezing your grinder before cleaning the kief, as this makes it harder for the resin to stick to things.

Alternatively, you can soak your grinder in a warm water, salt, and isopropyl solution after each use. This should make it easy to wipe clean.

If your grinder no longer functions well, even after a deep clean, it is time to replace it. You should also buy a new one if you’re unable to clean the sticky kief properly. It is possible to get a reasonably good four-piece grinder for around $50. However, the top brands can charge over $100. Care for it correctly, and it should last you a long time.
