Growing Harlequin seeds (indoors and outdoors)

Harlequin strain seeds grow into a sturdy and reliable strain resistant to pests and fungi. She is easy to grow and suitable for novice growers who want to grow CBD weed.

You can grow this beauty both indoors and outdoors. When growing indoors, it is advisable to train the plant. Harlequin can become quite large!

Are you growing outside? Then make sure you get enough sunlight and a place where the wind is not strong.

She is capable of producing large, heavy buds. Even so heavy that branches can break. Make sure you have enough support if necessary.

The plant is attractive, with bright green buds decorated with orange pistils and richly covered with frosty trichomes. To maintain the high CBD levels, it is advisable to keep an eye on the development of the trichomes and harvest as soon as the plant shows the first signs of doing so. The later you harvest, the lower the CBD values will eventually become.

Ensure the humidity is constantly 50% and that the temperature remains between 20 and 26 degrees Celsius for the best results.

Flowering time

When grown indoors, Harlequin has a short flowering time of only 8-9 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!

Plant height

Because of its predominantly Sativa characteristics, the Harlequin is a relatively large and wide plant that can reach a height of 2.5 meters outdoors in the open ground. So she needs a lot of space!

Harlequin feminized yield

Harlequin is known for her generous potential yields. Outdoors, one plant can yield up to 800 grams per plant. Indoors, yields are approximately up to 600 grams per m².

Growing hydroponically is advised to get the most out of your Harlequin feminized seeds.


Harlequin has an uplifting effect that fills you with euphoria. In addition, its Sativa-dominant properties (75%) can increase energy levels, making it 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.

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

Another beneficial effect of Harlequin is its 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.

Side effects

Harlequin can have several side effects that vary depending on the amount and duration of use. For example, beginning smokers may experience mild dizziness or headaches. In addition, dry mouth and eyes are also frequently indicated as side effects. Therefore, drink plenty of water both before and after consuming this weed.

Smell and taste of Harlequin

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


Harlequin's genetics come from Columbian Gold, Thai Sativa, Nepali Indica, and Swiss Sativa. It will be no surprise to hear that our Harlequin is a very effective pain reliever. In addition, our Harlequin is a 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 psychoactive effects.

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?

Daphne abel (Verified customer) 2019-09-01

I'm so happy!!! I have received my Harlequin baby seeds today!!! Thank you sooooooo much guys!

Flo (Verified customer) 2019-08-15

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.

Kauê Martins S. (Verified customer) 2019-06-15

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.

Victor Johnson (Verified customer) 2019-05-10

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"

J. Harding (Verified customer) 2019-05-07

Seeds arrived fast. Will start start soon.

shawn hazeleur (Verified customer) 2019-05-05

Jimmy (Verified customer) 2019-05-02

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.
