How to grow Harlequin
Seb's take
Colombian Gold, Thai and Swiss landraces again, though here the accent falls on function rather than force — a different creature entirely from the high-THC heavyweights sharing the shelf. Pine and floral notes lead, with a sweet musky mango underneath; social, relaxed and happy, mood lifted without the intoxication being the point. Talkative company, and honest about what it is.
Growing Harlequin: what to expect
Feminized photoperiod stock. You control when she flowers, which is a responsibility as much as a convenience; the light schedule guide keeps you on the right side of it.
She takes a conventional 9 weeks to flower. Conventional is underrated; so is knowing what week you're in.
Expect roughly 150 cm of plant. Manageable, though she'll appreciate a little training if your headroom is tight.
Expect 549 – 610 g/m² — a working grower's yield, reliable rather than theatrical. The harvest guide will see it in safely.
The listed THC is 6% — the gentler end of the scale, stated plainly. Harvest timing moves the needle more than most growers realise.
She smells of earth and heritage; nothing invented, nothing added.
The dominant note in the reviews is uplifting; daytime company, by most accounts.
