Tips for growing Harlequin cannabis

Advanced Nutrients logo
Presented By Advanced Nutrients June 25, 2017

This article is presented by Advanced Nutrients, a global company raising the bud weights and reputations of cannabis growers since 1999.


Strain overview: A sativa-dominant high-CBD strain, Harlequin was bred by crossing a Thai sativa, a Swiss landrace, and Colombian Gold. Its balanced levels of THC and CBD make it a unique strain with minimal psychoactive effects. CBD calms the high caused by THC, leaving the consumer feeling relaxed but not overwhelmed. Harlequin is popularly used by patients who wish to treat pain while remaining clear-headed and functional.

Grow techniques: CBD strains should be harvested early, as CBD levels degrade more rapidly than THC levels. The plant is a heavy yielder, so be prepared for large colas. Training the plants while keeping good airflow in the canopy leads to maximum yields. Harlequin grows well either hydroponically or in soil.

Flowering time: 8 weeks

Yield: High

Grow difficulty: Moderate

Climate: Keep between 72-85 degrees Fahrenheit. This strain can handle higher humidity levels, but keep good airflow in your garden.

Indoor/outdoor: Grows indoors or out, though a controlled environment will help the plant with its CBD production.

Feeding: Make sure Harlequin has access to soil nutrients by watering with compost tea. If growing hydroponically, give the plants lots of oxygen in the later stages of flowering to increase bud production.
