Read on to get to know more about this wonderful strain or buy your seeds directly.

What is Harlequin and what about her lineage?

Our breeders who bred the Harlequin feminized cannabis seeds have done well again. Test results have shown that the Harlequin CBD seeds grow plants with an extremely high CBD content of no less than 15-17% and a very low THC content of approximately 3% to 6%.

With the descendants of Columbian Gold, Thai Sativa, Nepali Indica and Swiss Sativa, the Harlequin strain is a great reliever in many ways. It is therefore not without reason that this species has become enormously popular among those who seek relief but at the same time want to remain clear in their head. Our Harlequin seeds are therefore an interesting choice for anyone who wants to grow a weed to relax with, without experiencing psychoactive effects.

Growing our Harlequin strain

Growing the strain is with the use of our Harlequin seeds fairly simple and straightforward. To get the best results growing outdoors is preferred where the strain receives sufficient (sunlight).

Top: whether you grow the Harlequin strain indoors or outdoors, the strain develops best when it’s about 22 – 29 degrees and the humidity around 50%.

Flowering time

Customers who buy our Harlequin seeds should take into account a flowering time of approximately 8 – 9 weeks when growing indoors.

Harvest and yield

Harlequin is known for its great yield potential. Outdoors, one plant can yield up to 600 grams. Indoors, the yield can reach up to 700 grams per m2.

Harvest time is approaching when pistils begin to change color from white to a red or a deep orange, brown like color. By that time the buds are covered with a thick layer of CBD trichomes and the quality is at its best. Yet, if you are chasing the highest CBD levels possible it’s recommended to harvest when about 80% to 85% of the pistils have changed color.

Appearance, plant height, structure and odor

Due to the predominantly sativa properties, the Harlequin strain is a relatively large plant, able to reach heights of 2.5 meters when grown outdoors. Moreover, the plant grows considerably in width. Sufficient space is therefore required when growing in big pots or in the open ground. The buds are bright green with orange pistils and richly covered with icy trichomes. During flowering you will smell the wonderful scent that can be both floral and spicy with notes of sweetness, citrus, mango and oak.


What has made the Harlequin especially successful is the ability to relax and numb the body without getting high. The calming effect on the mind also ensures the ability to stay focused, gain inspiration and become creative. You therefore retain 100% of your functionality and instead of slowing down or experiencing a couch-lock, you are accurate and get things done. This makes Harlequin the ultimate weed for consuming during the day.

The cross between Columbian Gold, Thai Sativa, Nepali Indica and Swiss Sativa has led to a unique terpene profile with a CBD THC ratio of 5:1. The high CBD content of this strain is an important indicator for its benefits hitting the sweet spot.


Harlequin is known for its delicious spicy flavors that range from sweet mango to earthy musk and fresh pine tones with a pleasantly creamy woody taste.

Although the smell of the smoke will not be overwhelming, the sweet smell of the plant is at least as pleasant as the taste. Especially due to the soft touch of fresh tropical mangos.

Harlequin Seeds

The connection between cannabis and medicine hasn’t always been as solid as it is today. Many years ago, people viewed cannabis as strictly recreational, if not downright illegal.

However, cannabis has found increased legitimacy through today in large part because the medical science community began seriously researching it.

Amongst the seemingly endless positive medical benefits derived from cannabis is its ability to defeat both pain and stress-related issues. But, what happens when you want the benefits of cannabis without getting stoned?

That’s where Harlequin weed comes in.

Does Harlequin get you high? Yes, but much less than normal THC strains because Harlequin is a high CBD strain.

About Harlequin Seeds


In the early days of cannabis cultivation, little was known about the different cannabinoids contained within them.

Nowadays, science is aware of 100 different cannabinoids, but the two that garner the most attention are THC and CBD.

THC, or tetrahydrocannabinol, is the cannabinoid that makes you feel high. In contrast, CBD, or cannabidiol, has an entirely different set of mainly medicinal effects.

Landrace strains tend to have high amounts of both THC and CBD concentrations. As cannabis has become increasingly cultivated, hybridized, and commercialized, the CBD component has mostly been bred out of the gene pool.

Why would you want a high CBD strain? The effects caused by THC are often too intense for people who want the medicinal relief cannabis delivers without the high.

Mr. Green, a cannabis breeder with House of David Collective, recognized the demand for a low THC, high CBD strain from medicinal patients. Many of these patients had never smoked weed before but knew there was much to gain from medicating with CBD.

In response, Green began the tedious process of hybridizing cannabis plants in the hopes of creating a high-CBD phenotype. His efforts were rewarded with Harlequin, a mostly sativa strain crossed with Colombian Gold and three landrace strains from Nepal, Thailand, and Switzerland.

Colombian Gold is itself an heirloom strain, meaning Harlequin seeds are packed with nearly 100% landrace origins.

Upon release, Harlequin seeds became widely dispersed across medical collectives as patients sought them out to treat both physical and psychological conditions.

Today, Harlequin seeds are equally loved by recreational stoners who appreciate the inner-calm brought on by smoking a bowl full of CBD-packed weed.

Growing Harlequin Seeds

A strain can deliver amazing flowers, aroma, taste, and effects, but if it’s a massive pain in the grow room, its popularity will remain pretty niche.

Harlequin seeds, on the other hand, have gone mainstream because they sprout, grow, and flower with little effort once you have your setup moderately dialed in.

Adding to the user-friendliness of Harlequin seeds is the availability of both feminized and regular seeds. Not sure which to choose? Here’s a quick summary to help you decide.

  • Feminized Harlequin seeds — These are the best Harlequin seeds to choose if you want to simplify your grow as much as possible. Feminized seeds are genetically pre-selected so that you only get female plants in the grow room. With feminized Harlequin seeds, you’ll reduce the time required from planting to harvesting.
  • Regular Harlequin seeds — Feminized seeds offer reduced effort in the grow room, so why would you want to get regular Harlequin seeds? If you want greater genetic diversity that lends your plants a full array of traits, regular seeds are the way to go. These seeds stay close to the original Harlequin cannabis strain and maintain their heirloom characteristics.

Grow Difficulty:

Harlequin is a high-CBD strain that is low on grow difficulty.

Remember, Harlequin is meant to give millions of medicinal patients access to potent cannabis-delivered relief. So, the Harlequin cannabis strain was selected for its ease of growth.

Optimal Growing Conditions and Climate:

The ease of growing Harlequin seeds indoors has everything to do with your ability to control climate conditions. CBD is normally found in landrace strains, and landrace strains require particular environmental conditions to thrive.

That’s why indoor growers tend to have more success with Harlequin seeds than outdoor growers do. Harlequin plants like warm environments and tend to do best in arid, dry climates.

If you’re growing Harlequin seeds outdoors in a humid environment, select a site with plenty of airflow rather than one obstructed by trees and other obstacles. Relative humidity should never exceed 65%.

Keep temperatures between 70°F and 83°F and your Harlequin seeds will reward you down the road.

Flowering Time:

Harlequin plants finish flowering in 8 to 9 weeks. To retain high CBD levels in the flowers, harvest your Harlequin plants early by plucking them when trichomes become glossy white.


Need a lot of medicine? Then you’re in luck because the Harlequin strain is a super heavy yielder.

Indoors, expect up to 25oz per square meter, while outdoor growers can harvest the same amount per plant.


Contrary to its mainly sativa genetics, Harlequin seeds grow into medium-tall plants that benefit from gentle LST techniques (Low-Stress Training).

Resistance to Pests and Mold:

Harlequin seeds are known for their innate resistance to many mold-based plant diseases.

Avoid bud rot by maintaining high air circulation to all parts of the plant, and during watering, include compost tea to increase plant immunity.

Strain Description and Properties

The Appearance of Harlequin Weed:

Just because people prize Harlequin weed for its chill, medicinal effects doesn’t mean it lacks in the looks department.

When you tear open a bag of Harlequin, you’ll notice a reflective glaze of frost coating the nugs from top to bottom.

Harlequin’s ability to produce crazy amounts of sugar is just the icing on the cake, however. The nugs themselves are massive, dense, and foxtailed to the point that some nugs resemble big green hands giving you the thumbs up.

Dominant Cannabinoids Found in Harlequin Seeds:

Harlequin seeds are CBD dominant but still contain THC.

In most Harlequin strains, CBD is present in levels of up to 10%, while THC is normally held back between 4% and 6%.

Dominant Terpenes Found in Harlequin Seeds:

Terpenes, and their interactions, are responsible for the endless array of flavors, aromas, and effects found in cannabis.

Harlequin seeds are heavy in three terpenes known for reducing pain while increasing a sense of well-being.

  • Myrcene — Known for its relaxing properties, myrcene quietly sedates the overactive mind while bringing herbal and floral aromas to the nose.
  • Pinene — Found in pine trees (surprise, surprise), pinene has calming, pain-fighting effects and also delivers verdant forest flavors and smells.
  • Caryophyllene — The most famous painkiller terpene, caryophyllene creates unique flavor profiles by contributing complex spice notes.

Effects of Harlequin Weed:

When it comes to smoking Harlequin Weed, the name of the game is relaxation.

THC strains sometimes test into the high 20% range, making it easy to get incredibly stoned from one hit alone.

Harlequin’s CBD-rich properties counteract the strength of THC but retain its non-psychoactive features. The result is you feel peaceful, relaxed, and remarkably clear-headed after smoking Harlequin.

Some Harlequin strain reviews have described the feeling as having an inner-light shining, bringing contented joy that never lapses into being overwhelmingly stoned.

If you’re new to smoking cannabis or want its relaxing effects without the couch-lock, the Harlequin CBD strain is an excellent choice.

Medical Properties of Harlequin Seeds:

Medical properties are the bread and butter of Harlequin seeds. After all, this strain was primarily created to deliver maximum relief to people treating effects stemming from chemotherapy.

Despite being an effective painkiller and inflammation fighter, Harlequin’s ability to bring about calm is a boon to those treating stress-related issues.

Harlequin is indicated for:

  • Pain
  • Inflammation
  • Nausea
  • Anxiety
  • Depression
  • Stress

Negative Effects of Harlequin Weed:

Because Harlequin weed contains only moderate to low amounts of THC, there are fewer negative effects when you smoke it.

Dry mouth and eyes are the most common complaints, but novice smokers may experience a touch of dizziness.
