Want better looking weed? Here’s how to increase trichome production.


Trichomes are the tiny, glittery crystals that cover the surface of your weed plant. These crystals are actually made up of cannabinoids, terpenes, and other compounds that give cannabis its unique effects.

Not only do trichomes make your weed look pretty, but they also play a big role in the plant’s overall potency. So, if you’re looking to grow better-looking weed, you’ll want to focus on boosting trichome production.

What are Trichomes

What are Trichomes?

Trichomes are an important part of the cannabis plant, and they play a big role in its ability to defend against insects, fungi, and other pests.

They also help to protect the plant from damage during harsh weather or exposure to harmful ultraviolet rays. Trichomes are not exclusive to cannabis plants, however; they are found on the majority of plant species.

Trichomes are tiny, crystal-like structures that cover the surface of the cannabis plant. These glandular hairs produce a resin that contains high concentrations of cannabinoids and terpenes, which are the active compounds in cannabis that give it its unique effects.

Cannabinoids like THC and CBD interact with the human body to produce various medicinal and psychoactive effects. Terpenes are responsible for the plant’s distinct aromas and flavors.

The resin produced by trichomes also helps to protect the plant from herbivores, pests, and extreme weather conditions.

The high concentrations of cannabinoids and terpenes make the resin unpalatable for most creatures, deterring them from eating the plant. The resin also has antifungal and antibacterial properties, which help to keep the plant healthy and free from disease.

How to Increase Trichome Production

Correct Grow Lights

As a home grower, you’ll need to be especially mindful of your plants’ lighting needs. Make sure to set your lights up directly above your plants, and adjust them as needed as your plants grow taller.

The light should be evenly distributed across the upper leaves and flowers for best results. Keep an eye on your plants and make sure they’re not getting too much or too little light – both can cause problems.

If you’re using LED lights, you’ll need to be especially careful not to overdo it. LEDs are very powerful and can easily overwhelm your plants if they’re not set up properly.

Make sure to consult with an expert before using LEDs, and start with a lower setting before gradually increasing the intensity.

Proper Nutrition

When your cannabis plants are flowering, they need different nutrients than they did during vegetative growth. During this stage, you’ll want to focus on providing them with macronutrients, micronutrients, and additional vitamins and amino acids.

The primary macronutrients can be remembered using the acronym NPK, which stands for nitrogen (N), phosphorus (P), and potassium (K). When your plants are flowering, they need less nitrogen and more phosphorus and potassium.

Other important macronutrients include calcium, magnesium, and sulfur. The micronutrients you’ll want are manganese, boron, iron, molybdenum, zinc, and copper. There are a lot of fertilizers on the market – make sure they contain these primary ingredients for a healthy grow cycle to produce lots of trichomes.

Monitor Temperature and Humidity

As cannabis growers are always looking for ways to produce more trichomes, one of the questions that often comes up is whether or not cold temperatures can encourage increased trichome production.

While you don’t want your plants growing in freezing conditions, colder temperatures can indeed promote greater trichome development.

Since heat is a natural enemy of trichomes, it stands to reason that cooler temperatures would be more favorable.

In fact, researchers have found that exposing cannabis plants to colder temperatures (around 10 degrees Celsius) for a period of two weeks can result in up to a 30% increase in trichome production.

Controlled Irrigation 

One way to increase your plant’s cannabinoid production is by keeping them in controlled hydric stress conditions. By giving them just enough water to survive, you can actually encourage them to produce more trichomes and cannabinoids.

Studies have shown that overall cannabinoid yields can increase by as much as 50% when plants are kept slightly drought-stressed. So, if you want to maximize your plant’s potential, consider letting them experience a slight drought during the flowering stages.

Just make sure not to overdo it and starve your plant of the water it needs to grow.
