The CBD sativa, as an autoflower
Harlequin made its name as one of the first widely grown strains bred for CBD rather than THC. Its lineage is a mix of old sativas, Colombian Gold, Thai and Swiss sativa, with a Nepali indica for structure, and the label lists it as 75% sativa with high CBD. This version is an autoflower, so it switches into bloom with age instead of waiting for longer nights.
The label sums up the flavour as earthy, herbal and spicy. In the room it is a grounded, green smell rather than a loud one, with a sweet, mango-like edge on some plants.
An easy auto with sativa habits
The label rates it easy. It is not fussy about feeding and recovers well from small mistakes. Expect the shape of a sativa-leaning plant: longer internodes, narrow leaflets and some stretch once flowering starts, which makes it simple to train into a wide, even canopy.

How to grow Harlequin Auto
Sow in the final container and run the light 18 to 20 hours a day from seedling to harvest. Begin low-stress training once the plant has four or five nodes, bending the main stem so the side branches catch up, and stop once flowers form. The label gives 8 to 9 weeks of flowering.
Feed lightly early on and increase once the plant is in flower. Outdoors, plant out after the last frost; it finishes in summer, before the autumn rain, and a long season leaves room for a second sowing.
