How do you prepare marijuana plant trimmings?

If you want to make the hash, the trickiest part is the extraction and manipulation of the cannabis trichomes. In order to remove as many cannabis trichomes as you can, you should do a couple of things. Here is what to consider:

1. Dry the plant materials

When making the hash, you should always ensure the plant material is as dry as possible. Therefore, you should not use freshly harvested marijuana in making the hash. Before making the hash, you can give the harvest at least ten days to dry.

2. Freeze the marijuana leaf

When the trichomes in the weed plant are sticky and gummy at warmer temperatures, it is not easy to extract them. Therefore, it is advisable to freeze the cannabis trimmings if you want to use them in making some quality hash. 

3. Get to a cold room

It doesn’t take too long for trichomes to warm up because they are tiny. That means you should do the last 24 hours of drying well. If you can, get a cold room in your home to make the hash. 

You should ensure the room temperature is at least 15 degrees Centigrade and below when making the hash. 

What are the Simplest Ways to Make a Hash?

1. Use a blender 

Cannabis plants pass through several stages of growth before they are ready for harvesting. During these development stages, the plants require different amounts of nutrients, water, and light. You must understand these stages, their durations, and what each plant needs at every stage. This will help you know when to train your plants. when to trellis them, and when they are ready for harvest. 

You can make hash using a blender from home. The first step is to fill the blender halfway with the cannabis plant matter. Add some cold water and ice into the blender to fill it up. Blend the mixture for a minute at full power, and then allow it to rest for some time, say five minutes. You can repeat this process at least five times. The more you blend the plant matter, the more hash you can extract.

Use a strainer to pour the mixture into a bowl to get rid of plant matter. Get a coffee filter and fill it up with the mixture until it’s 65% full. Pour some water into the filter to fill it up. This will make the solids in the mixture settle at the bottom of the filter. After an hour, pour out 65% of the mix to get rid of excess water and keep the residues at the bottom of the filter.

To collect the hash from the coffee filters, slowly pour the mixture into a second jar. If you want to make the process less tedious, dry it on the filter then remove it later using a credit card or a spoon.

2. Dry sifting

The first step to making hash from trimming is to freeze and cure the cannabis harvest. It is essential to ensure the marijuana is colder to break off the trichomes easily. Lay the marijuana across the screen, spread it out, and break it.

Spread the weed around by shaking it using a silkscreen. Ensure the screen you are using has a raised frame around it, or simply put it in a box. This way, you won’t lose a lot of plant matter to the wind. You can easily collect the hash when it goes through the screen.

3. Use a tumbler

You can try using a tumbler to make hash instead of using the silkscreen to turn cannabis trimmings into buds. Tumbler is a simple electronic device that can shake cannabis trimmings and shift them to a fine screen. Get some fine hash at the end and use less energy compared to the dry sifting method.

If you are only producing a small amount of hash, you may find it expensive to invest in a tumbler. It takes less effort to clean up when using a tumbler to make a hash. Also, if you are making large amounts of hash, you should get a tumbler to save time.

4. Hand rolling 

Hand rolling is probably the simplest way to make hash from marijuana trimmings. This method requires no special equipment and is therefore considered the most traditional method of making hash. It is also time-consuming and tiring.

When making hash by hand rolling, you should get non-dried cannabis and ensure your hands are as tidy as possible. You can use unscented and non-residual soap to wash your hands. Follow these steps to make the hash:

  • Remove all the stems and leaves in the cannabis bud
  • Place the cannabis bud between your palms and start rolling it in a circular motion. To avoid contaminating the hash with plant matter, you should avoid applying too much pressure on the bud.
  • When you begin to see some black and thick resin forming on your palms, this is the hash you should collect. Scrape the resin off your hands and press it to form a ball or block. 

How do you keep your hash from molding? 

Making hash from cannabis trimmings is not that easy. When you have your hash ready, you can keep it for the longest time away from mold by:

  • Ensuring the hash is completely dry before you can store it in a container. You can dry the hash in a room with 35% humidity and 55 degrees Fahrenheit. Also, you can invest in a freezer to ensure perfect drying.
  • Keep the hash in an airtight container or an amber glass jar. Always ensure no warmth gets into the container to stop bacteria from thriving and mold growing on the hash.


1. What is Hashish?

Hashish is a concentrated form of cannabis that has been compressed and heated to create. It can be smoked in a pipe or bong, the same way you would smoke marijuana.

2. What is the difference between hash and marijuana?

Hash is a type of cannabis that can be extracted from the plant. Hash is made by collecting and processing the resin that comes from marijuana plants, typically using ice water to separate it from other substances. Hash oil, which is created by extracting THC-rich resins with solvents like butane or hexane, has become popular for recreational use because it can create an intense high when smoked.

3. What are the effects of Hash?

The effects of homemade hash can vary depending on the person and the amount taken. Some people have reported a sense of euphoria, as well as increased appetite. Others report feeling more relaxed or sleepy. The most common effect is an increase in heart rate and blood pressure.

4. How long does it take to make 1 gram of hashish?

The process of making a hash takes a lot of time and effort. The first step is to harvest the Cannabis plant. Next, the leaves are trimmed off and then they are dried out in a dark place for about one week. After that, the stems are removed from the leaves by hand or with machinery, depending on how much is being processed at once. Then, it’s ground up into a powder form using either an electric grinder or mortar and pestle until it becomes flour consistency (see also grinder pens).

5. What is the best way to store hashish?

Hashish can be stored in a freezer, refrigerator, or in a sealed container at room temperature.

I discovered the benefits of Cannabis at a young age in 2002, with years of trial and error, my knowledge grew just like my plants. As my love for cannabis unfolded I began to teach and learn, trying to gain as much information and practical growing experience.

  • Head line says how to make hash from trimmings but it talks about growing it and nothing about making hash. If I didn’t know how to grow it I sure wouldn’t be looking on making hash from it. Been growing for 50+ years.

    • Thank you for pointing that out, James! We accidentally pushed the wrong post. Everything should be updated now!
