Basic infos

Harlequin CBD 40:1 is an mostly sativa from Plantation Premium Seeds and can be cultivated indoors and outdoors (Where the plants will need a flowering time of ±58 days) Plantation Premium Seeds 's Harlequin CBD 40:1 is Without THC is only available as feminized seeds.

Plantation Premium Seeds Description

Harlequin CBD 40:1 feminized seeds represent one of the most precisely bred high-CBD cultivars available, delivering a cannabinoid profile that consistently tests at approximately 20% CBD against less than 0.5% THC. This photoperiod sativa-dominant strain was developed specifically for therapeutic cultivation, producing plants that offer functional, clear-headed relief without psychoactive effect. Each seed in this feminised pack eliminates the guesswork of male identification, making the ratio reliable from seed to harvest.

Genetics & Lineage

Harlequin draws from four distinct landrace lineages: Colombian Gold, Nepali Indica, Thai landrace, and a Swiss landrace. This genetic combination places the strain at roughly 75% sativa and 25% indica in its overall expression. The Colombian Gold and Thai genetics contribute vigorous upright growth and long internodal spacing, while the Nepali Indica component introduces structural resilience and shortens the flowering window. The Swiss landrace is understood to be the primary contributor to the stabilised CBD dominance in this line. The 40:1 CBD-to-THC ratio represents a carefully selected phenotypic expression bred through multiple generations of cannabinoid-focused stabilisation.

Aroma, Flavour & Effects

The terpene profile is led by myrcene, caryophyllene, and pinene, producing an aroma that reads as earthy and woody at the base with distinct notes of fresh mango and light pine on top. When dried and cured properly, the flavour carries a mild sweetness alongside herbal and slightly spiced undertones. Effects are non-intoxicating at the stated cannabinoid ratio — users report a calm, grounded physical ease with no impairment to cognition or motor function. Onset is gradual, typically felt within 10 to 20 minutes when consumed, making it well-suited for consistent daytime use. The sativa structure of the genetics adds a subtle alertness to the body-focused relaxation rather than sedation.

Growing Profile

Harlequin CBD 40:1 feminized is a photoperiod strain requiring a light schedule change to 12/12 to initiate flowering. Indoor flowering time runs 55 to 60 days, with indoor yields averaging 400 to 500g per square metre under optimised lighting conditions such as 600W HPS or equivalent LED coverage. Outdoor plants grown in full sun finish in early to mid October in the northern hemisphere, with individual plants capable of yielding 500g or more under strong seasonal conditions. Height can reach 120 to 150cm indoors and up to 200cm outdoors given the sativa dominance, so low-stress training or light topping early in the vegetative stage helps manage canopy spread. The strain demonstrates solid resistance to mould and humidity fluctuation, which is a practical benefit given its dense upper colas. Soil or coco media with consistent moderate feeding suits its landrace-influenced feeding requirements — overfeeding nitrogen late in flower can dull terpene expression.

Who This Strain Is For

This strain is the primary choice for growers cultivating specifically for high-CBD therapeutic use — whether for personal wellness, formulation into extracts, or CBD-dominant infusions. The stable 40:1 ratio makes it dependable for anyone who needs a consistent, measurable CBD source from their own garden. Beginners benefit from the feminised format and the strain's inherent hardiness; experienced growers will appreciate the clean terpene output and the response to light training techniques. A greenhouse or polytunnel environment extends the outdoor season and protects late-season colas in cooler climates.

A well-documented, genetically stable CBD cultivar that performs consistently across a range of grow environments — Harlequin 40:1 delivers what most high-CBD strains only approximate.
