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.

Elev8 Seeds – Harlequin CBD

Flowering Time: 8-9 weeks
Yield: Good
Potency: High 9.1% cbd – 6.5% thc

Harlequin has gained a following as a high CBD strain since it was discovered. CBD has proven to be an effective treatment for PTSD, chronic pain, arthritis, multiple sclerosis, sleep disorders, fibromyalgia, anxiety, etc. CBD counteracts THC’s paranoia while amplifying its painkilling properties.

These feminized seeds are made from two Harlequin females. The benefit of feminized seeds in CBD strains is that phenotype expression can sometimes be more predicable in the offspring, producing a more consistent CBD to THC ratio.

Flavors range from earthy musk to sweet mango but what makes Harlequin so popular is its ability to relax without sedation and to relieve without intoxication.

After harvesting seeds from the plant, we had the strain tested by a nearby lab. Generally, plants that have produced seeds tend to test lower in Cannabinoids than unpollinated females but these tests still came in on the high end of other Harlequin tests throughout the country.
