Effects & Usage



Harlequin is a sativa-dominant strain known for its high CBD content, often displaying a 5:2 CBD to THC ratio. A descendant of Colombian Gold and three landrace strains, Harlequin’s genetic lineage contributes to its remarkable cannabinoid profile. This results in a gentle and balanced experience, offering therapeutic benefits and subtle mental uplift without overwhelming psychoactive effects.


The effects of Harlequin are akin to a slow, delicate dance. It is a very gentle experience, characterised primarily by a mood uplift. It will induce happiness and release all kinds of tension, mental and physical. Whilst not necessarily an energising strain per se, it will help you get your work done by removing any obstacles that usually distract you.

You should not feel too many psychoactive effects, as the high CBD content counteracts the action of THC. Therefore, you will remain very clear-headed, just feeling positive and lighter, as if all your burdens were taken off your shoulders.

Thanks to its versatility and gentle effects, Harlequin can be used anytime and in any setting. It can be an excellent wake-and-bake strain for anyone who wants to remain active throughout the day but needs a little boost to take on the day’s challenges. Evening use is equally beneficial, as Harlequin’s soothing properties can ease tension after a long day, promoting relaxation and restful sleep.

It will be great for solo use as well as before socialising, particularly if you feel nervous about meeting new people or being in a crowd.

Thanks to its balanced cannabinoid profile, Harlequin can be used for various conditions. Its impressive CBD content, working synergistically with THC and the anti-inflammatory terpenes caryophyllene and pinene, provides significant pain relief in conditions like fibromyalgia, arthritis, neuropathy, chronic pain etc. Those looking for a strain to calm their mind and get a positive outlook on life will also find Harlequin particularly helpful.

Side effects

The side effects associated with Harlequin consumption are generally mild and manageable, including dry mouth, itchy eyes, and occasional dizziness. Given its balanced CBD-to-THC ratio, Harlequin is less likely to cause anxiety or paranoia than high-THC strains. As always, consuming responsibly and being mindful of your tolerance is essential.

Taste & Smell


Harlequin has a gentle, sweet smell with classic earthy notes complemented by woody soil aromas. This bouquet brings forest scents to mind, with subtle hints of mango, adding a refreshing zest to the overall smell. The taste is similar to the aroma, with a solid herbal, earthy base, rounded off by pine notes on the inhale, and finished with a creamy, woody flavour on the exhale. The creamy notes tend to linger on the tongue, leaving a soothing aftertaste that is as comforting as it is exquisite.

As for the appearance, it features tight, dark green coloured, dense buds of medium size interspersed with vivid orange-red pistils. Despite a lower-than-average THC count, there are still noticeable trichomes on the flower’s surface.



Harlequin is one of the oldest high-CBD strains, created from Colombian Gold and a mix of three landrace strains: Thai and Swiss sativas and a Nepalese indica. This diverse genetic background gave rise to a strain that offers a unique balance of therapeutic benefits and mild psychoactive effects, making it a standout in the world of medicinal cannabis.

Growing conditions

Growing Harlequin requires a bit of attention to detail but can be successfully attempted by both novice and experienced cultivators. A few things, however, need to be kept in mind. The strain is susceptible to humidity levels, which must be consistently maintained at around 50%. It is also quite sensitive to pests and fungi. These factors are easier to control indoors, which is the preferred setting for growing the strain.

Successful growers will be pleased with Harlequin’s bountiful yields. Expect the flowering period to take around 8-9 weeks, providing you with about 600 grams per square metre indoors and 700 grams per plant outdoors.
