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.
Where it comes from
Colombian Gold, Thai and Swiss sativa landraces combined — a genuinely international pedigree, and a low-THC, high-CBD one at that. Where most modern strains chase potency, this one is built around function: a gentle, talkative character rather than a heavy hitter. The Colombian Gold traces to the mountains its name suggests, the Thai and Swiss filling out the sativa frame. A very different creature from the shelf's heavyweights, and content to be.
Nose & flavour
Pine and floral notes lead — that classic green freshness — with a sweet, musky mango running underneath and an earthy floral depth beneath that. A bright, herbal nose, easy and unhurried. Pleasant rather than pungent, in keeping with the whole.
The high
Social, relaxed and happy — a clear, talkative lift with the mood raised but the intoxication kept modest. The low THC and higher CBD mean the effect stays functional throughout, which is rather the appeal. Good company for a room, and honest about what it is.
Growing it
A sativa-dominant plant of roughly 150cm, flowering in 56 to 70 days, with generous yields of 549 to 610 g/m². The cannabinoid balance is the headline: 3 to 6% THC set against 6 to 8.5% CBD. That balance shapes everything about her gentle character. A straightforward grower whose reward is temperament rather than firepower.
