Harlequin Grow Info

Harlequin is a cannabis strain that is easy to grow both indoors and outdoors but thrives in a controlled environment. It can be grown hydroponically or in soil and produces large buds.

To promote healthy growth, keep the temperature between 72 and 85 degrees Fahrenheit. Although Harlequin can tolerate higher humidity levels, it is essential to ensure good airflow to avoid mold and pests.

To keep pests and mold at bay, maintain a relative humidity (RH) level below 65% during the vegetative stage and gradually reduce it below 55% during the flowering stage. The good news is that relative humidity can drop to 30-40% near harvest time.

Watering with compost tea can provide good nutrients to the soil, while hydroponically grown plants require plenty of oxygen in the later stages of flowering to increase bud production.

Low-stress training (LST) or high-stress training (HST) techniques can also improve overall performance. Proper application of these methods can expose the entire plant to more light and airflow.

It is important to note that CBD strains should be harvested early as CBD levels degrade more quickly than THC levels.

Harlequin Strain Flowering Time


Indoor this strain typically takes 8 to 9 weeks to be ready for harvest.


When grown outdoors Harlequin will be ready to harvest in mid-October.

Harlequin Yield

Indoors, Harlequin can yield around 25 ounces of potent bud per square meter, while outdoors, it can produce an average of 21 ounces per plant at harvest.

Harlequin Origin

Harlequin is a rare strain created by crossing four different landrace strains: Nepali Indica, Thai Sativa, Colombian Gold, and Swiss Sativa strains. These strains have been cultivated for centuries in their native regions and have adapted to various climates and conditions. Harlequin inherits some of the best traits from each of these varieties.

  • Nepali strain provides Harlequin with its high CBD content and earthy, musky flavor, which also contributes to its calming effects.
  • Thai strain, on the other hand, adds a Sativa dominance and an invigorating, energizing effect, as well as a fruity, citrus flavor.
  • Colombian strain is responsible for Harlequin’s low THC content and balanced, smooth effect, as well as its sweet, floral flavor.
  • Swiss strain contributes to genetic stability, resistance to parasites and diseases, and a spicy, herbaceous flavor.

Harlequin offers the best of both worlds: high CBD and low THC levels for medical users looking for relief without intoxication, sativa dominance for users looking for stimulation without anxiety, and genetic diversity for growers who want quality without the hassle.
