Best Weed Grinder: 2020 Top Picks and Buying Guide

A finer and more powderized pot delivers a more potent high. Stems and seeds are a useless filler that contain far less THC and could be harmful to your health, so trash them if you find them (unless you want to grow).

Grinding marijuana creates a more workable and efficient form, resulting in smoother, tastier, and more satisfying smoking, vaping or edible experience.

Most popular grinders are built with chambers to separate the potent, tiny trichomes from the flowers. When collected the residue is called kief, a condensed and stronger version of the plants’ beneficial compounds (namely THC). Kief (pictured below) can be added to joints, blunts, bongs, vapes, smoked by itself or used to make cannabutter,  tinctures, oils, and cannabutter.

What is a weed grinder? Well, it’s a small device that makes a cannabis user’s life a heck of a lot more convenient. Basically, it chops up your weed efficiently and consistently produces a smooth grind (or at least, it should). Of course, not all weed grinders are the same. Some are manual while others are electric. Some are duds while others require you to pay top dollar. The list goes on. So, if you’re in the market for a really good weed grinder (read that: the best), then you should know exactly what to look for. This guide gives you an in-depth look at the features of the best weed grinders so you’ll be sure to always get the best high from your bud.

Marijuana has to be shredded or ground so that it burns better; finely ground ganja exposes more of the THC crystals or trichomes to the heat source during combustion and thus gets you higher, giving you more potent effects from whatever cannabis strain you are smoking or vaping – the finer the cut, the more THC is released. Also, ground weed fits in your weed bowl or dry weed vape chamber better. Yes, you can grind weed without a grinder simply by tearing nugs of cannabis flower apart with your fingers. But that is a pretty inefficient way, because you end up burning big chunks in your weed bowl, ashing the outside while the inside is unburned, and when you tear up your buds of marijuana all the cannabinoid-laden resin and kief get all over your oily fingers – that’s THC you aren’t smoking (however, you can rub your fingers together until the resin balls up and grows as it collects more resin, making hash! Believe us, investing in a grinder with proper grinding teeth and maybe even a pollen catcher is well worth it!

From simple weed grinders to ones that collect your kief in a special compartment, all weed grinders generally function the same. You fill a weed grinder's grinding compartment with flower and close the lid. You spin and rotate the lid hard enough to break apart your marijuana until you feel little resistance. This is the sign that your weed has been ground and is in a separate chamber.

A weed grinder with only one compartment will house all the weed in one place, which can make it a bit more difficult to keep from falling out when taking the lid off again. Herb grinders with multiple chambers hold the granulated flower in compartments below and sift kief through a pollen screen below that.

There are two main types on the market – manual and electric.

Obviously, a manual weed grinder requires you to put in some effort. Not as much as cutting up the buds yourself but still a bit of effort – twisting the top of the device to ground down the buds. This isn’t really a hardship but it’s not as fast as an electric weed grinder. However, these give you more control regarding the consistency of the grind. Manual grinders are also easier to clean and generally last longer.

Electric grinders, on the other hand, do all the work for you. If you’re going for one of these, you should look for one that has long battery life (it should last a couple of sessions before recharging), a large grinding chamber, and a kief catcher (if you want one). Your electric grinder should also be easy to use, whether it’s loading your weed into the chamber or pouring it directly into your vaporizer.

Weed grinders differ based on the number of compartments built in the device.

A weed grinder with 1 compartment (also known as two-piece grinders) is just that. The grinding chamber where you load the weed and where it is ground is also where you’ll be retrieving the weed. What people like about this type of grinder is that it’s pretty intuitive compared to grinders with multiple chambers which is perfect for beginners. However, there are times when the size of the pieces isn’t consistent. And collecting the ground herb afterwards can be a pain with all the teeth in the way.

A 2-compartment weed grinder is exactly what the name implies. This device consists of three pieces (the lid and the two chambers). The first chamber is the grinding chamber where all the teeth are and where you’ll be placing the weed. At the bottom of this chamber are holes where the ground herb will fall through. Because only a certain size can fall through, you collect a more even grind compared to the 1-compartment device. Retrieving the ground herb is a lot more convenient as well.

A 3-compartment device is also called a 4-piece grinder. Aside from the two chambers, you get a third one at the bottom that is separated from the second chamber by a fine screen that sifts through the ground herb and lets the kief fall down to the last chamber.

1) Disassemble your weed grinder, remove any leftover weed by scraping the parts with a nail or some sturdy wire.

2) Fill a large, airtight glass container with 91% isopropyl alcohol.

3) Submerge your herb grinder's pieces in the alcohol-filled airtight glass container and seal the lid.

4) Gently shake the glass container to loosen any remaining bits of old weed, set the jar aside and wait ten minutes, letting your weed grinder pieces soak.

5) After you remove your herb grinder from the alcohol-filled airtight glass container, scrub away any remaining resin or material with a cotton swab or washcloth dipped in the same alcohol you soaked the grinder in. For those who have an herb grinder with a kief-collecting metal mesh screen, you can gently scrub the strainer mesh screen clean of leftover pot plant material with a tooth brush or baby bottle brush.

6) Let your weed grinder dry in your dish drainer until completely dry and then reassemble so that it is ready to grind your ganja again!

A Herb Grinders is an essential piece of cannabis smoking and vaping for many reasons. For one, weed grinders enable you to break down cannabis flower into smaller pieces that you can use to roll a joint or pack a bowl. Without a weed grinder, you're still able to use your fingers to crumble your flower, but your hands will be sticky with trichomes by the end.
