Why you should buy feminized Harlequin seeds:

  • One of the most sought-after CBD seeds in Oregon (USA), the UK, and Canada

  • Great for medicinal purposes

  • Uplifting, energizing effects

  • Easy to grow

  • A great harvest potential

  • Fast flowering

  • Sturdy and mold resistant cannabis seeds

Flowering time

When grown indoors, Harlequin has a short flowering time of only eight to nine weeks. That's pretty fast for a Sativa dominant strain!

You can harvest between September and October when growing the Harlequin cannabis seeds outdoors in the Northern Hemisphere. So early in the fall for these fast flowering weed seeds!


Harlequin marijuana seeds are known for their generous potential yields.

Outdoors, one plant can yield up to 800 grams per plant. Indoors, these high yield weed seeds can provide you with up to 600 grams per m².


Harlequin has an uplifting effect that fills you with euphoria. In addition, her Sativa-dominant properties (75%) can increase energy levels, making her the ideal smoke to get you going in the morning.

Harlequin's energy-boosting properties help you feel motivated to finish your chores and get on with your day. It is therefore often used by people suffering from depression.

Harlequin weed also can manage pain and anxiety due to her high CBD content. She also combines well with high THC strains because CBD can dampen the effect of THC.

Another beneficial effect of Harlequin is her ability to increase appetite. For example, this can be very beneficial for patients who have recently undergone chemotherapy or have a general lack of appetite.

CBD and THC Level

Our Harlequin is a marijuana strain with an extremely high CBD content of at least 10-15% and a maximum THC content of 6%.

Moreover, Harlequin is an intriguing choice for anyone who wants to relax without experiencing major psychoactive effects.

Smell & Flavors

During both flowering and after the maturation process, you will smell a wonderful aroma that can be both earthy and herbal with notes of pepper, citrus, and oak.

The taste of Harlequin strain weed has been described as spicy with pine notes. A delightful smell and taste that, above all, is not overpowering.


Because of her predominantly Sativa characteristics, Harlequin plants can grow relatively large and wide.

These female plants can reach a height of 2.5 meters outdoors in the open ground, so they need a lot of space!


Harlequin's genetics come from Colombian Gold, Thai Sativa, Nepali Indica, and Swiss Sativa. It will be no surprise to hear that our Harlequin strain can be a very effective pain reliever.

In addition, this high CBD strain has been awarded for her efforts. As Cannabis Cup seeds, Harlequin has claimed the bronze medal for the CBD Awards at the 2012 High Times Cannabis Cup in NorCal.
