Harlequin brings bright, clear-headed energy with a gentle, easygoing feel. Its CBD-forward profile, low THC, and uplifting Sativa character make it a standout choice for growers seeking a mellow, daytime-friendly cultivar with distinctive herbal-pine flavor.
Our breeders trace Harlequin’s lineage to Colombian Gold, Thai, and Swiss Sativa. The result is a feminized hybrid with a 75% Sativa and 25% Indica profile, shaped for a lively growth pattern and a balanced cannabinoid profile. Expect 3–6% THC and 6–8.5% CBD.
A fresh herbal aroma meets crisp pine, with soft earthy notes and a hint of sweetness beneath. Dense buds develop a frosty coat of resinous trichomes, adding visual appeal and making the harvest a fine candidate for extracts and concentrates.
Harlequin’s effects are happy, relaxed, and talkative. Its low THC content keeps the experience gentle, while its CBD-rich profile complements a clear, composed mood. It’s a thoughtful pick for growers interested in a softer, more measured experience.
Alpha-pinene, caryophyllene, linalool, terpineol, and trans-nerolidol shape this cultivar’s aromatic character. The profile suits growers looking for a versatile variety associated with fatigue, muscle spasms, and stress. Individual experiences vary.
These feminized seeds produce female plants, and germination is guaranteed. Harlequin is beginner-friendly and grows indoors or outdoors in a tropical climate. Its 8–10-week flowering window makes planning straightforward, while its 1.5 m height offers a manageable structure.
Start with quality soil, coco coir, or another well-draining medium. Give seedlings steady nutrition, then adjust feeding as plants move through vegetative growth and flowering. Keep air moving and monitor humidity to help prevent pests and mildew. Indoors, use ScrOG to create an even canopy and encourage productive lower branches.
Harlequin develops a tall central stem with strong side branches. Provide ample light and room for airflow, and keep temperatures around 21–27°C. For indoor grows, aim for 55–60% relative humidity in veg and reduce it as flowering progresses. Outdoors, choose a sunny, well-drained site with a relatively dry environment.
Allow 8–10 weeks of flowering indoors. With attentive care, indoor yields can reach 550–600 g/m²; outdoor plants can produce around 700 g each. Plants may reach 1.5 m, and outdoor harvest is typically in October. Give the resinous flowers time to mature and finish strong.
