Blimburn Seeds runs this as a sativa feminized line — 20-25% THC lab range, fruity/citrus-dominant terps, 8-10 weeks from flip.

Blimburn Seeds lists this at $25.98 — the lowest base price in the comparison ($25.98 floor). Pack options: 3-seed at $25.98, 5-seed at $36.20, plus larger sizes.

Smell-first: crack a cured bud and you get bright citrus up front, a thread of stone-fruit sweetness behind it, then dry earth on the exhale — a sequence that holds up across multiple phenotypes from this Blimburn line. The plant itself runs 8–10 weeks to finish and pushes 400–500 g/m² under decent light, which is a reasonable return for a sativa-leaning grow that tops out around 20–25% THC. Height can stretch, so topping or LST early keeps things manageable indoors; outdoors it handles both humid and dry-ish climates without throwing fits. Difficulty sits at moderate — not a beginner hand-holder, but nothing that demands a PhD either. Effects lean cerebral and clear-headed rather than couch-heavy, which matters if you're growing specifically for daytime use.

Best suited to intermediate growers who want a sativa-dominant plant that finishes on a predictable schedule without sacrificing yield.

Genetics & Lineage

Harlequin traces its genetics to Harlequin (Blimburn Seeds). This sativa-dominant feminized seed produces plants that express the best traits of its parent lineage, delivering consistent results for growers of all experience levels. Bred by Blimburn Seeds, each seed is selected for genetic stability, terpene expression, and vigor.

Effects & Experience

Users report primarily relaxed and euphoric effects, making this strain ideal for evening use and unwinding after a long day. The body-centered stone builds gradually, easing tension and promoting deep physical relaxation. With THC levels reaching 23%, this offers a well-balanced experience suitable for most users with some cannabis familiarity.

THC Level & Potency

Harlequin delivers THC levels of 20-25%, placing it in the moderate-to-strong range that most regular consumers find comfortable. CBD content is minimal, so the psychoactive effects are front and center. The onset typically arrives within minutes, starting as a cerebral buzz that gradually expands.

Growing Harlequin

Harlequin is rated as moderate difficulty, making it suitable for growers with some experience. Basic knowledge of nutrient schedules, pH management, and environmental controls will help maximize results.

Indoor Growing: Expect a flowering time of 8-10 weeks with yields of 400-500g/m2. Plants typically reach 100-180cm indoors. Standard training techniques like topping and LST will help manage height and improve light penetration. Maintain temperatures between 68-80°F with relative humidity around 45-55% during flowering.

Outdoor Growing: This versatile strain performs well in both indoor and outdoor environments. Outdoor growers in warm climates can expect harvest from late September through October. Watch for humidity during late flowering to prevent bud rot, especially with dense flower formations.

Flavor, Aroma & Terpene Profile

Harlequin features a fruity, citrus, earthy, pine terpene profile that develops complexity throughout the flowering cycle. Sweet berry and grape notes dominate the inhale, with a sugary exhale that lingers on the palate. The aroma intensifies significantly during the final 2-3 weeks of flowering — carbon filtration is recommended for indoor grows requiring discretion.

Medical Benefits

While individual experiences vary, Harlequin is commonly reported to help with stress relief, chronic pain, insomnia, and muscle tension. The deeply relaxing effects make it a popular choice among medical users seeking nighttime relief. As with any cannabis strain, start with a low dose and increase gradually. Consult a healthcare professional before using cannabis for medical purposes.

Who Should Grow Harlequin?

This strain is ideal for intermediate growers ready to push their skills and be rewarded with superior results. If you're looking for evening relaxation and deep stress relief, this is your strain.
