Why You Need a Cannabis Grinder and How to Best Use it

Breaking up cannabis, whether you do it with a grinder or manually, is a minor but essential aspect of the smoking session. Every seasoned cannabis user has a preferred method for grinding their cannabis.

It doesn’t matter if you’re a recreational or medical cannabis user – investing in a good marijuana grinder can benefit you in many ways. Most cost just $10 a piece – you’ve got absolutely nothing to lose and, for a fact, you’re making things a lot faster and convenient for yourself at the end of the day.

If you prefer to consume your cannabis in edible form, a grinder can be very useful as it will quickly let you prepare your herb for cooking or baking, even if you’re not using an extractor.

What is a Marijuana Grinder Exactly? Components Explained

It’s unfortunate that grinders don’t get as much press like the rest of the ‘cool cannabis accessories’ like vaping devices, dabbing rigs and blunt rolling papers, for instance. However, they are an essential piece of the cannabis preparation process that no connoisseur should bypass.

Before we explain how to make the most of a cannabis grinder, let’s quickly go over what it is and how it works.

A grinder is a small palm-sized container that has ‘teeth’ capable of effortlessly grinding chunks of cannabis into, well, smaller and finer chunks. It’s also one of the best ways to extract kief from your herb.

All cannabis grinders have three main components: the grinding chamber, teeth/pegs to do the grinding, and a lid to keep it secured inside.

Sounds pretty basic, right? Sounds simple in theory but grinders are available in several sizes – it’s up to you to decide what you need. At a glance, there are three types of grinders common among cannabis users:

  • Single chamber 2-piece grinder
  • Twin-chamber 3-piece grinder
  • Tri-chamber 4-piece grinder

If you find these naming conventions potentially confusing, here are brief explanations to set the record straight:

Single Chamber

Two-piece grinders, as one might imagine, has 2 basic components: a hockey-puck sized bowl (the single chamber) and a lid. When you secure the lid over the bowl, you have a single chamber.


Imagine a 2-piece grinder which has a lid and a bowl. Add one more piece underneath. So you have three pieces, isn’t that right?

Starting from the top, you have the lid, which has teeth/peg to do the actual grinding. Right below the lid is the grinding chamber, which may also have teeth/pegs. So, in a 3-piece twin-chamber grinder, the base of the grinding chamber has holes so that the ground-up bud can fall through – the former (2-piece grinder) will not have those holes.

When you chop up your herb into fine pieces in the grinder, it falls right through the holes and into the collection chamber. All you have to do is unscrew the bottom chamber for the collected herb to be used.

To quickly reiterate – you have a collection chamber, grinding bowl and a lid – this constitutes a 2-chamber/3-piece grinder.

In this configuration, the collection chamber houses a tiny mesh screen rather than a solid, flat bottom. Right under the collection chamber is the ‘magic compartment’ – the kief chamber.

As you keep grinding, the larger ground-up buds collect up in the collection chamber. Without pausing, the consistent grinding will lead to small materials that resemble pollens – these fall through the mesh screen and into the bottom chamber. That’s your kief.

Just to reiterate – you have a collection chamber and screen, grinding bowl, lid and kief chamber at the very bottom – which constitutes a 3-chamber/4-piece grinder.

Since we’re now familiar with the common types of grinders available and their underlying components, let’s shed some light on why so many cannabis users prefer using grinders:

Benefits and Uses of Cannabis Grinders

Cannabis bud trichomes is where the highest concentrations of cannabinoids (CBD and THC) as well as terpenes are found. You really want to extract these tiny, frosty crystals, especially if you’re consuming high quality cannabis strains.

Grinding cannabis in a grinder is done mainly for two reasons – first and foremost, to get a nice and even, solid burn in your bowl, blunt or joint; and second, to have heat evenly distributed over nearly every trichome – allowing you to extract the most ‘goodness’ from your cannabis bud material.

An important aspect to consider when it comes to cannabis grinding, is that the grinding consistency fairly depends on how you intent to consume your herb. For instance, if you prefer smoking your herb in a bong, you definitely do not want to make the mistake of grinding too finely as it may actually enter the pipe, causing you to cough unnecessarily due to the much harsher hits.

It’s a no-brainer that cannabis needs to be grinded properly to enjoy the best effects – in addition, here are specific benefits of using a cannabis grinder:

Improved Consistency

Without a doubt, the best way to ground your cannabis evenly is through a grinder. This is an important step because it ensures that the extraction of the plant’s compounds is even – whether you prefer using a traditional pipe or a vaporiser.

If you happen to be a blunt or joint smoker, consistently ground cannabis makes for an even burn all the way to the end, and also ensures easy rolling.

Ideally, you’d really want to get a grinder just to cut your herb to an even consistency every single time.

Larger and Denser Bowls

You’ve probably heard many consumers swearing by the fact that loading up whole or loosely broken buds into bongs or pipes produces really potent hits. However, we would suggest grinding your product every time to get the best, most potent hits.

When you grind your stuff, you can easily pack it into bigger and denser bowls. Sure, you’ll end up using more product to fill out the bowl properly – but you don’t have to do this every time and can certainly fill your bowl up half way if you like.

By grounding up your cannabis properly, what you’re doing is increasing the surface area of the stuff that’s in your bowl – which equals not only a more potent, but a cleaner burn. Furthermore, ground bud in your bowl means easier draws, making the overall experience more enjoyable.

Thicker Vapour

Many among us prefer to use a vaporiser and that’s great too! In this case, we’d highly recommend cannabis that’s grounded properly. Since vaporisers work on the basis of the convective heating or conductive heating principle, grinding your cannabis means you’re exposing a higher surface area to the heat – allowing for improved extraction of those wonderful compounds present in the buds.

On the other hand, if you attempt to load a whole bud or one that is not properly grinded, you’re not going to get that highly desirable thick and consistent vapour – due to insufficient heat from the vape which is needed to toast the bud’s core.

Your Super-easy Guide to Using a Marijuana Grinder

Here it is – an easy-to-follow, step-by-step guide:

Load Your Grinder

Twist and remove the lid. Using your fingers, break the initial piece of cannabis into smaller pieces. There’s no need to place anything in the middle of your herb grinder because this space is simply there to allow everything to pivot.

Grind Your Herb

Now replace the lid and firmly hold the base of the grinder with one hand. Rotate the lid with the other. You may feel a bit of resistance at first, so simply rotate the grinder until this resistance is gone.

Tap the Grinder

It’s important to follow this step before you remove the lid on either one of the collection chambers – give the grinder a tap against the palm of your hand or a table top. This will dislodge your stuff into the collection chamber. Why do we do this? To push as much kief as possible through the mesh screen.

Collect Your Herb

Now, we’ll go ahead and separate the collection chamber from the grinding chamber to scoop out the freshly ground herb. If you’re using a tri-chamber (4-piece) grinder, be extra careful as we don’t want to damage the screen.

Upon your very first attempt, you may notice that hardly any kief comes out – however, upon separating the kief chamber from the collection chamber, you’ll notice that it will be eventually full of the wonderful powdery delight.

You’re All Set!

We’re done with the grinding. Now, it’s up to you to decide what you want to do with the cannabis grounds. For example, you could:

  • Steep a little marijuana tea
  • Make a batch of edibles
  • Roll a joint
  • Pack a bowl

If you’re the patient kind, however, you can take this a step further to make cannabis extracts, oils, tinctures or isolates.

To conclude, there are hardly any downsides to using a grinder – in fact, now that we think about it, there are none!

What’s the best cannabis grinder?

In order to smoke or process our buds, it’s usually necessary to break up the buds first, especially if they’re really dense!

Most growers chop or grind their marijuana buds so they are easier to use!

When smoking, grinding help your buds go further by “aerating” the buds (make them fluffy) so they burn more efficiently. This is can make buds feel stronger and last longer compared to breaking it up with your fingers!

Dense buds like this are extremely difficult to break up properly with your fingers

Most common tools for grinding or chopping cannabis:

  1. Hands/fingers – just okay
  2. Scissors – a little better than using your hands
  3. Grinders from Around the House – tools that are meant to grind herbs, coffee and tobacco all do a pretty good job with cannabis, too. However, these usually don’t have any way to catch kief that falls off your buds.
  4. Specially Made Cannabis Grinders – these can go from terrible to great, depending on the model!

There are a millions ways to chop up your cannabis, and many work well, but if you are serious about getting the most from your buds, there’s a style of grinder that rules them all.

Grinders that are made for marijuana come in many different colors and models….

But which grinder works the best for weed?

4-Piece Cosmic Case – The Best Cannabis Grinder!

Important Note: Unfortunately, production of the Cosmic grinder seems to have halted. We’re devastated by the loss of this first-rate grinder, but we’re currently testing dozens(!) to find the next best thing. For now, we’re using our old Cosmic grinders and the Santa Cruz Shredder, which has been a good backup. If you have a grinder for us to try, let us know here!

I’ve used dozens of grinders over the years, and some are definitely better than others! Many of them can be a really great choice, but there’s one to rule them all.

Now-a-days, I will only use a 4-piece Cosmic Case grinder. It may not look like anything special (though they do come in various colors and sizes), but that’s not what makes it great. Its greatness lies in the fact that it is has been designed by cannabis connoisseurs from the bottom up.

First, let me warn you about the price… They’re realllllllly expensive. I’m talking up to $90 for their large models!

That may seem obscene, and it honestly is an obscene price for a grinder (which are normally closer to $15).

But if you grind up a lot of bud in your life, I think it’s worth it to invest in a Cosmic Case. I only got one because a guy at a head shop convinced me, but I’m glad he did because I’ve used them ever since.

About the Cosmic Case Grinder

It’s a sturdy piece of metal with good weight to it, and it has an overall very solid design.

The 4-piece “Large” version looks like this when you open it up.

Like all high-end grinders, it comes with a kief trap to collect all the kief/trichomes/glitter that naturally comes off your buds during the grinding process. That way you have kief for later!

Note: When a grinder is labeled as a “4-piece” grinder, the 4th piece is the kief trap (often called a “pollen trap” by sellers).

Kief/trichomes collect in the pollen trap so you can use it later!

It also has a very strong magnetic top that lets you easily open it up, yet the magnet is strong enough that it won’t fall off on its own even if you hold it upside down or keep it in a purse or backpack all day. This may seem like a small thing, but it’s a huge improvement over grinders with weak magnets (where the top comes off all the time) or screw-on tops (which get all gunked up after a while and won’t screw off easily anymore).

Those are great features that you should get from any high-quality grinder! However, the Cosmic Case has something else that makes it special….
What Makes It the Best Grinder?

The thing that makes this grinder so great is the weird holes it uses. They look like they’re going to let all your bud through in huge pieces because they’re so much larger than standard holes, but it doesn’t actually do that.

For whatever reason, these oddly shaped holes are just plain better (in my opinion) than the regular round ones. They shear the buds into a different consistency than normal grinders, and buds never get ground to dust.

The uniquely shaped holes shear your buds instead of grinding them into powder

The shearing makes any buds kind of fluffy, even if you’re using dense buds that are tough to break up.

I have found that buds actually seem stronger/more potent compared to not grinding them because the ground bud burns all the way through evenly in just one breath. This makes buds last longer since you use less at a time (though it can give you a head rush!).

The buds become fluffy due to the shearing action – this extra air makes buds burn better and they’ll often actually feel more potent!

It works great even with extremely dense buds!

Check out the 4-Piece Cosmic Case on Amazon!

When you use a great grinder like this, your buds will feel more potent and as a result, your buds will last longer. Despite the cost, these are a good investment! It’s a top-notch present for a fellow enthusiast, or as a present to yourself, and I know you’ll become a believer as soon as you try one the first time!

What is a Grinder and how do I use it?

Weed grinder is one of the many objects and devices that have emerged in the Grow shop market over the last few decades. The professionalization of the sector has led to the emergence of hundreds or thousands of gadgets that make life easier for both growers and consumers of cannabis. Grinder is one of the best-selling cannabis paraphernalia products, but do we know what it is.

⭐ What’s a grinder?

The Spanish translation of grinder is “amolador”, which would be something like a chopper or shredder, so when we say “grindar” or “grindear” we mean to chop or grind the weed.

A grinder is a small object composed of at least 2 parts, which are separated to leave a gap between the two to place our buds. This hollow or internal chamber contains different protrusions or spikes that, when turned, intertwine with each other, crushing the dried flower to leave it in small and homogeneous pieces, perfect for rolling and consuming.

Cannabis grinders are usually metallic, made of wood or plastic, originally they were made of wood and with internal steel spikes. Nowadays there are thousands of different models of grinders, of many materials, colors and even different uses. Would you like to see some of them? Continue reading…

⛳ What is a grinder used for?

Their main mission is to grind cannabis. When we chop weed and it is crushed in a homogeneous way the joint combustion in an adequate way, this is due to the fact that it can be pressed better when the pieces of bud are smaller. In this way it burns uniformly, achieving a more consistent taste.

Another advantage is that marijuana is used more, because when you grind the weed by hand a lot of resin remains attached to our skin, and they are lost trichomes, the most valuable part of the plant. And how did we do to grind cannabis before the invention of the grinder?

Normally scissors or hands were used directly, but it took longer and as we saw before it was much worse.

✨ Types of grinder

It would be impossible to name all the types of Grinder for chopping cannabis that we have on the market, so we will make a selection of the best of each kind:

    : Right now they are the most common, their low manufacturing price has led many companies in the grow sector to have their own grinders for advertising, giving them away massively at fairs, cannabic cups and other events.
  • Metallic grinder: They are usually the most expensive, but they can also last much longer than plastic grinders. They are usually magnetized, very easy to clean, and there are many different models.
  • Wooden grinder: It is the favorite bud chopper of the puritans, many have engraved drawings, and with good maintenance can last forever.
  • Quick grinder: It is metallic, made with first quality materials, and the finish seems to have left the Apple factory, turns like a Mercedes engine and chops up the marijuana like no other. To facilitate the evacuation of the cannabis once chopped, contains 2 external buttons so you do not even have to clean it so much. : For the most comfortable ones, with this grinder you won’t have to turn to grind, just put the bud, press the button, and your weed will be chopped.
  • Grinder card: It was one of the last models on the market, its operation is similar to that of a cheese grater, rubbing the bud against the blades of the relief and gradually crumbling.
  • Grinder with pollinator: Probably they are the ones that take advantage better of the marijuana, since they contain a lower chamber where the Kief that the buds release is deposited. This way nothing escapes.
  • Grinder clock: This is a occultation model, at first it looks like you wear a normal watch, but contains a simple grinder that goes completely unnoticed.
  • Homemade grinder: We’ve seen friends or customers make their own homemade grinder, in some cases it even worked well, but most, made with caps and other everyday objects, weren’t worth it. Honestly, because of the cost and the work involved in making it at home, I don’t think it’s a good solution.
  • Grinder with storage: It is a mixture between a jar to store and transport buds, and a grinder. It is made of very hard and resistant plastic and is very practical when you leave home.
  • Grinder with mill: It has a crank to turn the mechanism that chops weed, it is striking and some contain a pollinator to collect the Kief.

Apart from these there are many more types, shaped like dice, others that look like billiard balls, comic characters, or even insects.

How to use a weed grinder?

Well, this depends on the model of course, but in general what is done is to separate the parts of the grinder, place the dry cannabis inside, close by joining both parts, turn while squeezing a little, and reopen to evacuate the ground pot.

So it is done with the great majority of models, those of plastic, wood, Quick grinder and many others are based on that performance. The one with mill also, although in this case contains a crank to facilitate its operation.

Here are some animated gifts that show you how a normal grinder works step by step:

How to use a grinder with pollinator?

The operation of the grinder with pollinator is similar to other types. The difference is that this model contains a chamber at the bottom where it accumulates the kief released by the buds during crushing.

The grinder is uncovered and a bud is introduced, closed and turned a few turns, so far it works as usual. Then the lower half is unscrewed, which contains both the compartment where the ground weed is, and the chamber that holds the kief, which is also unscrewed and separated. These 2 lower parts are separated by a mesh of approximately 150 microns.

How do I get pollen out of the grinder?

To evacuate the pollen or kief accumulated in the grinder is very simple. You only have to unscrew the lower chamber, and with the help of a spike, or a small spatula we scrape well inside, also the mesh where is usually trapped enough resin, and throw it on a baking paper or similar.

When we remove the kief or pollen the ideal is to take advantage to clean the mesh that filters and the rest of the grinder with the help of alcohol, so that it always works perfectly.

How do I use the grinder card?

It is very easy, its operation is similar to a cheese grater. As you will see, the grinder card contains some small holes in the surface, which have sharp edges. These holes are used to filter the small pieces of buds when they are cut.

The ideal thing is to prepare a tray so that those pieces of weed fall on it, it is also worth a paper or any container. Then we take the grinder card with one hand, and with the other the bud we want to consume. We rub the bud on the surface of the card where it has the holes, from one side to the other and doing some pressure, as when we grate cheese, but controlling that the chopped weed falls on the tray or what we have prepared. Then all that’s left is to roll or carry the cannabis and enjoy.

This is an invention with a very simple operation, which added to its low price, small size and easy maintenance, make it a very interesting article for smokers.

✅ How to crush or grind grass without a grinder?

Years ago scissors were used to cut weed and still some purist users use them today. It takes more time and work but the result is not bad to roll a joint, although the grinder is much more efficient.

Another way to grind weed without a grinder is to chop marijuana by hand, we’ve all used this method once and we have found that it is not a very interesting option. A good part of the bud resin remains adhered to our fingers, the better is the marijuana that we are going to grind, the more resin is wasted. This is bad because apart from losing many of our trichomes, it prevents you from rolling the joint easily afterwards, since the paper sticks to your resinous fingers.

Tips for using and maintaining the grinder

One of the most important things when using the grinder to grind cannabis is to consider our health. I see a lot of people who take a whole bud, put it inside, make 3 or 4 turns, open it and make a joint with all crushed vegetable material, even stems! Don’t do it please, before grinding the cannabis make sure you have removed all the stems that the bud contains, you must try to reduce the risks associated with combustion.

The central part of the grinder chops less than by its perimeter, this is because in the center no matter how much you turn there will be hardly any friction, that’s why it is more interesting to put the dry flowers in any part of the perimeter that in the center.Another important point in the maintenance of a grinder is the cleanliness. As we know, cannabis resin is very sticky, it adheres to any surface, especially when we squeeze and break. With each joint we make, we accumulate resin in the spikes and chambers of the grinder, and gradually begins to have an impact on how it works, which is increasingly difficult to turn or close it properly.
