Alchimia is pleased to present Harlequin by Blimburn Seeds, a variety known in the US for its benefits as it can help to alleviate several pathologies thanks to its THC/CBD concentration. This variety is now available in our feminised cannabis seeds catalogue.

Harlequin, cannabis with moderate THC and CBD levels

Harlequin is a Sativa dominant cannabis genetics, an encounter between Colombian Gold x Thai x Swiss Sativa. It has a great recognition in the US where it is attributed excellent properties for its therapeutic potential. Its CBD/THC content can help mitigate anxiety, stress and depression among other pathologies.

Harlequin offers a THC level up to 3-6%, and a CBD concentration between 6-8.5%.

Harlequin, a productive cannabis easy to grow

Harlequin is a plant of small size with abundant secondary ramification. It is a plant easy to cultivate in any type of culture, yet indoors is the best option. This is because it is recommended to maintain a humidity level of 30-50% in the flowering period and reduce it to 30-40% two weeks before harvest.

Harlequin presents a flowering period of about 7-10 weeks, with a yield of up to 550-600g per m2. Outdoors it can produce a yield of up to 700g per plant.

Harlequin produces a pleasant high effect thanks to the moderate THC concentration, very suitable for recreational use as well.

Harlequin, a sweet and sociable cannabis strain
