Harley Quinn CBD Seeds

Harlequin is one of the most well-known high-CBD strains in cannabis, combining four landrace and heritage genetics to produce a reliable 5:2 CBD-to-THC ratio. With 10–15% CBD and 7–15% THC, this sativa-dominant strain delivers clear-headed, functional effects without heavy psychoactivity.

Genetics & Lineage

Harlequin is a four-way cross of Colombian Gold x Nepali Indica x Thai Sativa x Swiss Sativa. This diverse landrace heritage gives it stability and resilience, while the combination of sativa-dominant genetics with CBD expression creates the balanced cannabinoid profile the strain is known for. The CBD content is consistent across phenotypes, making it one of the most reliable high-CBD strains available.

Appearance

Plants grow tall with a sativa structure, often exceeding 2 meters outdoors. Buds are elongated and moderately dense with bright green coloration and orange pistils. Trichome coverage is good, though less frosty than THC-dominant strains. The plant’s vigor and branching make it well-suited for outdoor growing.

Aroma & Flavor

The nose combines citrus, earthy, and mango notes with a musky sweetness. On the inhale, expect earthy wood and spice. The exhale carries herbal notes with a sweet mango undertone. The flavor is smooth and pleasant — less pungent than high-THC strains.

Effects

With a 5:2 CBD:THC ratio (typically 10–15% CBD and 7–15% THC), Harlequin delivers clear-headed, functional effects. Users report feeling relaxed without sedation, focused, and mentally clear. The high CBD content moderates the THC, keeping the experience gentle and manageable. An excellent daytime strain for those who want relief without impairment.

Growing Information

Harlequin flowers in 8–9 weeks indoors with impressive yields of 650–700 g/m². Outdoors, expect 550–600 g per plant with harvest in mid-October. The plants are resilient with good pest and mold resistance. Easy to moderate difficulty. Prefers temperate conditions around 21–27°C. The tall sativa structure benefits from topping and training indoors.
