Planning to grow a powerful Sativa dominant strain (75% -25%) and chasing high CBD levels? Check our Harlequin feminized seeds. The Harlequin strain is very potent when it comes to CBD, features a lot of advantages and has become very popular since 2015. Curious why? 

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.

I'm now in the middle of the flowering fase. The leaves were really yellow, so added some potatssium fertilizer and the plant regained it's color. Im really statisfied with how everything is going and growing.

Kennedy-Condreay Christine (verified customer) 2020-01-18

Loved growing this plant a couple of them had irredecent leaves, (bonus!) my only gripe was that when we had it lab tested (we are a commercial medical grow) was that it tested .8 thc to 18.6 cbd. Way lower than 4:1 I was expecting. Almost = hemp?

Had some germination issues with the first batch of these seeds but the replacement did very well especially with the provided germination information.

anonymous (verified customer) 2019-06-21

I grew this strain for my aunt she has some health issues, don't want to get into details and all but she is really benefiting from this strain with the high cbd and a lower thc but also she notice the thc a bit for the mental part of healing; i also like it myself usually i am more into the higher thc strains but it always keeps me from doing stuff and with this strain my body feels right right and my mind is clear enough to do daytime work what i do as a part time employee i wont bother you but well.

This product is great, looks better than other seedbanks and the pricing here is fairly reasonable. I have grown Harlies in the past and this is the real deal, at week 9 of growing hydro, will share photo's soon.

levimoore (verified customer) 2019-06-04

exactly as advertised. 9 germinated out of 10 and they all came up. i would also give you a 9 out of 10 for shipment and discreetness. Will be back for more.

As a US Vet I have many physical and mental healt issues like insomnia, anxiety, chronis pac pain, pain in my arm because of a fracture. After 4 years of taking pain killers I have turned my back to these opiods. That stuff was killing me slowely. After doing some research Harlequin seems to be my best bet and yes, i can assure you it is your best bet. The quality of my life has improved enormously. I sleep much better, i feel much better and my chronic pain has decreased tremendously so guys, thank you, thank you, thank you. The only downside: my first order was taken by customs so it took a pretty long time before I could start growing. Hence the 4 stars instead of 5 but that's really my only "complaint"

I love the Harlequin, it is a real painkiller to me and my mind gets satisfied also. I started to grow my own harlequin and finished a few weeks ago with seeds from the express. I sent some pics to David, they are stunning right? Thanks for the help WSE.

Harlequin has been nothing else but a miracle for my varied health problems. #0 years old and never grew a strain before, I felt the urge to grow my own med cause I am sick of those pills. I got some help from the support desk and my plants are doing good! As a friend is helping me out, the buds aren't as big as they supposed cause I did made some beginner mistakes. 2 weeks from harvesting and I can't wait to throw the pills away and bake some eatables harlequin weed.
