Things to consider before buying:

Benefits of weed grinders

It’s good to grind your dry herbs because it makes your herb to have a larger surface area, making it easily exposed to heat. The large surface will eventually lead to smooth heating of your herbs. Therefore, you can enjoy powerful vapor and a bigger draw from your vaping instrument.

Grinders allow you to maximize the use of dry herbs even in minimal quantities. Smoothly grinding your herbs always results in optimal effects with little effort.

The use of a grinder also saves your budget because you get to spend less money on herbs. You also get to save money used on batteries and less time spent on vaping session.

Grinders can also accumulate kief from dry herb. Kief is the most potent component of the cannabis plant which is known to make the user very high. A grinder can help you extract kief which can further be used to make hash. The kief that remains in the grinder can be used for different purposes.

Types of weed grinders

Weed grinders can have two, three, four parts based on your preferable style. Consumers can choose between 2-piece Grinder, 3-piece Grinder, and 4-piece Grinder.

2-piece Grinder

A 2-piece Grinder has just a single compartment for herbs. It can grind and store your cannabis. Since it’s relatively cheaper than ordinary grinders, users have complained about it producing inconsistent sizes of herbs. People on a budget should preferably get this grinder because it offers convenience at a lower price.

3-piece Grinder

A 3-piece Grinder has two compartments for herbs. The link between the two compartments is made possible by holes at the bottom part of the upper layer, which leads to the second compartment. The holes can accommodate only specific sizes of herbs, and this makes the first compartment to have a larger surface area. Therefore consumers can enjoy evenly ground herbs from the three piece grinder in contrast to the 2-piece version. Users can also easily retrieve their herbs from the second compartment. 

4-piece Grinder

A 4-piece Grinder has three compartments for herbs. The third and second layer are connected through a single mesh screen. The third compartment also known as the pollen catcher is meant for storing kief.

The Pollen catcher can store all the fine particles that fall off from the 2-piece and 3-piece compartments. Four piece grinders can grind all types of herbs including cannabis

    Frequently Asked Questions

    What are grinders made out of?

    There exist different types of weed grinders to choose from including wood, metal, and acrylic. Premium grinders are manufactured from quality metals including stainless steel, anodized aluminum, and even titanium. Grinders can also be made out of wood, but most wood grinders have only a single chamber.

    Most grinders contain magnets which form part of a reliable and straightforward lid closure system. Grinders also include textured grips and ergonomic designs that are useful to patients suffering from severe conditions.

    What are the different parts of weed grinders?

    Grinders consist of chambers that are manually operated such as single-chamber, two-piece models and three-chamber, and four-piece varieties. Grinders with a single chamber are very easy to use and are often inexpensive.

    The first compartment to have a larger surface area which can grind large quantities of herbs without any issue. The second compartment then stores the cannabis which has been grounded, so users can easily retrieve their herbs from the second compartment.

    Most three-chamber and four-chamber grinders have an established fine screen for capturing the trichomes of the bud while blocking most plant matter going through. There is also a spare chamber within the grinder which stores kief. Premium grinders have an additional chamber which allows storing dry kief, or trichomes and trichome heads, which can be used for other essential purposes.

    How do you clean weed grinders?

    There are several methods for cleaning a grinder. A preferable approach is by taking the grinder apart and place the individual parts in the freezer for about an hour. After the parts become frozen, you can tap it into a paper towel or your rolling tray to remove the debris. Clean grinders are very sharp, and they tend to last longer.

    Another preferable method for cleaning a grinder is by dipping by using alcohol. Just soak cotton into rubbing alcohol and clean the edges of the different parts surrounding the teeth. Alcohol functions by removing any grime or residue.

    When alcohol weakens the resin, use a toothpick to remove the grime until the grinder becomes clean. After removing the dirt, you can rinse the grinder well in warm water and dry thoroughly.

    Can grinders grind fresh herbs?

    Grinders can grind almost anything. They are best suited for semi-dry to dry herbs, spices, and large seeds, but can undoubtedly grind fresh herbs as well. If you are grinding basil or oregano or other delicate herbs, you should preferably dry the herbs overnight or for a few days for the best outcome.

    How do you regulate the outcome of the grind?

    Grinding your cannabis through the teeth and into the collection chamber will result in a medium grind. But you can grind harder by turning the grinder sideways and turn the top lid several times. This will lead to a powerful grind. Turning your grinder upright for a few times will make your ingredients to move through the holes into the lowest chamber.

    How much weed should you put in the grinder?

    Grinders work at their best if you don’t over pack them. Start filling the grinder with little amounts of the dried flower until it becomes full. Purely grounded herbs can pass freely through the pipes. After filling your grinder, you can begin grinding until when you notice that there is no more resistance while twisting the separate parts of the grinder. 

    What type of weed do you put in a grinder?

    It’s preferable to use the dry herb in a grinder because it’s smooth and won't block the holes of your grinder. Also, dry herbs release kief in powdery form.
