How To Trim Your Cannabis Flowers

What is Trimming?

Harvest day has come, and we all know what that means; trim time. Also known as manicuring, trimming is a process that involves removing fan leaves and sugar leaves from cannabis plants so only the bud remains. The flowers contain the majority of the cannabinoids we are aiming to produce, so most growers tend to aim for as much bud as possible. Leaves and stems are not harmful to smoke, but they contain sugars and other compounds which are not desirable for a smooth smoke.

Why Trim Cannabis?

Most growers are on a mission to produce the purest cannabinoid product they can muster up. Depending on your level, trimming takes a fair amount of work and it's easy to get lazy or try to speed through it quickly. Most of the time, a trimmer shaves the leaves off around the bud, which means a large part of the leaves still remain in the bud. Weed still tastes perfectly nice this way, but a deeper trim could take it that step further.

Trimming cannabis is done for various reasons and it depends on how the final product is going to be consumed. If the plan is to smoke the final product, then a more thorough trim is favoured to remove anything except the flower. For edibles and other types of extract, a proper trim isn't as necessary because the goal is to collect as many trichomes as possible.

However, one can still perform a decent trim and still have plenty of trichome-rich sugar leaves to make extracts from. Although the result may not be as potent (you'll need more volume of plant material), sugar leaves are a great way to squeeze some extra juice out of your ladies.

Materials for Trimming Cannabis

In order to trim buds quickly and efficiently, it helps to have the proper tools. Otherwise you may unnecessarily spend way longer than you need to and the process begins to drag on. Learning to trim takes practice, but it will be much easier if you use the right equipment.

  • Disposable gloves (preferably ones without talcon powder) - Gloves help to protect both you and your plants. Wearing gloves while you handle buds help to reduce the damage and removal of trichomes. In addition, the resin won't stick to your skin, which is difficult to remove and smells strong.
  • Spare clothes - Even with gloves, you're likely to stink of weed after a trimming session and you probably won't even notice the smell after having been surrounded by buds for hours. If you do a lot of work trimming, it's best to keep a spare set of clothes for the job.
  • Shears - A pair of high quality garden clippers allows you to remove branches from a cannabis plant with ease in preparation for trimming. These are ideal for cutting through tick, fibrous growth but are not designed for trimming, which requires more precision. Of course, you can use these to trim with too if you want, but they won't be as efficient.

Resin Builds Up On Scissors From Wet Trimming

  • Precision trimming scissors - This is your main trimming tool and it needs to be taken care of. Trimming scissors can be cleaned with rubbing alcohol or vinegar. The longer you allow resin to build up on the ends of the scissors, the less effective they become. However, you'll likely be giving them a bit of a clean regularly anyway to sample some of that stinky scissor hash.
  • Bucket or tray - Having some kind of container over which you can trim means you can easily collect all the sugar leaves for processing later on. A sterile bucket or tray does the job nicely and will save you some cleaning at the end of the day.
  • Drying rack or hangers - Whether you are dry or wet trimming, you need an appropriate place to dry your buds. Knowing how you are going to dry your buds has an effect on the trimming. Some growers trim and hang whole branches, others trim them down into individual sections and place them on a drying rack.

Drying Cannabis

How To Trim Cannabis Flowers

There are two main ways growers manicure their buds. Wet trimming and dry trimming are both acceptable ways of removing excess leaves, but is one better than the other? This depends on the environment you are drying/curing in, as well as how much effort you want to put in and whether you mind potency being affected over flavour.

Wet Trimming

Wet Trimming

Trimming your weed before it dries is called 'wet trimming'. Leaves still hold most of their moisture when they are freshly harvested, making them much easier to access.

When a cannabis plant is still wet, more of the leaves are exposed, and they point outwards. As the leaves dry, they curl and shrink into the bud, meaning they are trickier to remove without damaging the trichomes or breaking the flower.

On the downside, wet trimming is a sticky process and things can get pretty messy. Be ready to clean you trimming scissors regularly, otherwise you'll quickly get resin build up that becomes particularly hard to deal with. Sugar leaves get stuck everywhere.

Be sure to monitor humidity levels for drying and curing. High humidity during drying is a recipe for mold disaster so many growers prefer to wet trim. However, be careful not to dry your plants too quickly. Fast-drying plants results in a bad tasting product, so wet trimming is best performed when the humidity is not too low.

Benefits of Wet Trimming:

  • Good for overly humid climates
  • Helps to prevent mold
  • Leaves are more accessible
  • Less damage to trichomes

Dry Trimming

Dry Trimming

As you might have guessed, dry trimming is the process of removing leaves after the buds have already dried. Once the stems 'crack', usually after 10-14 days (if the buds have not dried too quickly), it is time to dry trim.

The process is much faster than wet trimming, as most the leaves just break off without trouble. Dry trimming is also cleaner and you won't be going nuts over a few sugar leaves constantly clogging up your scissors.

The ease of trimming this way comes with a price; a loss of the precious trichomes we worked so hard to create. If you have ever dry trimmed you may have noticed how easily the trichomes 'shower' off a bud with just a snip of the stem below it. The trichomes become brittle as they lose their moisture.

Although it might not make a huge difference, buds are likely to lose potency because of dry trimming. It may be necessary to dry trim if you have problems keeping the humidity levels up. Slow drying helps to remove chlorophyll and generally the final product has a better taste.

Benefits of Dry Trimming:

  • Cannabis can be dried slowly
  • Improved flavour
  • Useful for extremely low humidity areas
  • Faster than wet trimming

Making Use of Trim

While you're trimming, you may be wondering how you can make use of all that sparkly stuff you just chopped off. Trim can be processed in a few ways but the idea is to strip it of all the cannabinoids it has left to make other cannabis products.

It helps if you separate the sugar leaves from fan leaves during the trimming stage. There's no point trying to make extracts from leaves that don't have any resin on them.


Hash Can Be Made From Cannabis Trim

Making kief or hash is a great way to make use out of the sugar leaves. There are loads of different ways to extract the trichomes to make all kinds of different hash. Most methods involve using a type of screen to sift or catch trichomes, which are collected and normally pressed.

For example, bubble hash is usually made by freezing sugar leaves, rinsing them in an ice cold tumbler then filtering out the water through special screens (bubble bags), which catch the trichomes. These are collected and the remaining moisture is evaporated/soaked out of the 'hash' to leave a pure cannabinoid product.


Cannabutter Made With Trim

Alternatively, there are plenty of extraction techniques which allow you to cook more easily with your leftover trim. Cannabis butter, oil and tinctures are a few of the more commonly made cooking ingredients using trim. The trim can be simmered or soaked using different edible substances, which act as a base to hold the cannabinoids and help to strip the goodness off the leaves.
