The 5 Best Methods for Collecting Kief 420 Culture

Here at PotGuide, we recently covered some of the ways to put your kief collection to good use, and we figured that it might be a good time to go over some of the ways to collect that kief in the first place. In general, there are three ways of collecting kief without the use of solvents: shake it off, freeze it off, or force through a screen to be caught in some form of reservoir. The best collection methods combine these methods to capture as many trichomes as possible. Take a look below to learn more and start collecting that precious kief!

Four-Piece Grinders

The standard and by far most popular method of collecting kief is to use a four-piece grinder. The distinction from a two- or three-piece grinder is that it will have a “kief catcher,” a chamber in the bottom beneath a fine screen to catch the kief that falls off of your buds when shredded.

A quality grinder need not be expensive, budtenders and head shop workers will usually have a good tip on which work best.

Many utilize the “coin trick” to get better efficiency out of their grinders’ kief catchers. Putting a coin in the middle chamber helps to knock trichomes off of the flower as well as push them through the screen to the collection chamber below. It’s important to wash the coin well before putting it in with your flower to avoid contaminants and ridge-less coins tend to work best (better surface contact). 

Pollen Boxes

Small pollen boxes, can be slightly time consuming for getting large yields, but are easy and tidy for small personal batches. Simply put some buds in the top and shake. The biggest benefit of pollen boxes are that they keep everything nicely contained, so you don’t have to worry about a gust of wind or clumsy roommate coming by and scattering your work to the wind. However for larger yields, you’ll want to scale up.

Silk Screens

Silk screens can help you collect a pretty decent amount of kief in a short amount of time. To do so, you’ll need to take a trip to your local art store to grab a silk screen, the very same you might buy to DIY a few band t-shirts. For this method, a basin or clean surface is set to catch the kief underneath (a pane of glass or mirror works well) and then ground or shredded cannabis plant material is gently run over the screen to separate out the kief.

This method is ideal for medium-sized batches of plant matter. One downside to using silk screens is that they can tear easily from stems. It’s best to be gentle and work slowly, picking out any jagged pieces that might tear. Metal screens are available in this size as well, but can be harder to come by. 

Hashish Drums

The oldest kief method is to create a drum with a silk screen. The screen is stretched over the whole drum basin (often just a plastic bucket), and then covered with a selection of bud or trimmings. Next, a tarp is secured over the top with a rubber band or tight rope, locking the plant material in between the tarp and the silk screen. This is then beaten with sticks and the kief falls through the silk screen. With the right micron-gage silk (the unit of measurement for small particles), one could easily make a traditional Moroccan kief drum at home. This is an ideal setup for larger amounts of plant matter, but also easy to scale in size.

Freezing Methods

For the ultimate kief collection method, we start introducing a little science. THC is not water soluble, meaning it won’t dissolve in water, and colder trichomes become more brittle and fall off with greater ease. This means that any method of freezing won’t disturb the THC, while making the kief easier to agitate and collect. Dry ice alone, or (or even your trusty freezer) can be used to cool the buds to a point where the kief can be shaken off in a jar or container. Freezing prior to using the coin and grinder trick will also improve yields.

However, submerging the plant in an ice bath with get the most out of it, one just needs to be able to collect the kief back out. To do so, hash producers use a dry ice bath and what’s known as a “bubble bag,” a type of sieve sleeve (say that five times fast) traditionally used for making bubble hash. Plant matter is put in the middle of the bag then stirred in the ice bath forcing the bud against the screen. The resulting kief is collected underneath the screen.

This is essentially the freezing method with a screen and collector attached to it and is ideal for collecting some of the highest quality kief, as the process can be repeated with finer and finer screens bags to get only the head of the trichome (ensuring the least possible amount of plant matter). It works well for large batches, a it’s possible to get quality hash out of things like trim and clippings this way as well.

Naturally, a large factor in how much kief accumulates is the quality of the cannabis plant to begin with. Buds with heavy trichome coverage will yield more kief and produce a higher quality smoke.

Ask your budtender to help select well-sugared strains in order to maximize yield. Also, wearing gloves, or using an object to manipulate the plant matter is ideal to minimize oil residue from your hands (which will also make the kief clump up). Happy kief collecting!
