Colombian Black by Breeder Choice Organisation

If you want to talk about true, unadulterated landrace preservation, you have to talk about Colombian Black from the Breeder Choice Organisation (BCO). Sourced directly from the Llanos Orientales region of Colombia back in December 2002 by a legendary BCO member known as 'Aldous,' this is a pure sativa genotype that commands absolute respect. It gets its name from the striking blackish-green to almost pure black flowers it produces. The old heads theorize these genetics were originally brought to Colombia by African populations, which explains the completely unique, old-world terpene profile—a crazy blend of dark anise and black licorice that you just don't find in modern polyhybrids.
Growing Colombian Black is not for the faint of heart; it’s a massive commitment. We're talking about an extreme flowering time of around 150 days, or roughly 21 to 22 weeks. Because of this endless flowering cycle, it’s generally strictly grown by hardcore landrace preservationists and specialized growers who have the patience and the ceiling height to handle her. It was never released as feminized stock, meaning growers had to sex the plants and run them out through grueling cycles. Despite the long wait, she’s hardy, stress-resistant, and typically throws two primary phenotypes that both deliver a soaring, clear-headed, positive mental stimulation with almost zero body drag.
On forums like ICMag and Rollitup, BCO's work is legendary among the older crowd who remember the early 2000s push for sativa preservation. You have to be careful today, though—some modern seed banks have released strains called 'Colombian Black' that have absolutely nothing to do with this original landrace line. Genuine BCO seeds are essentially priceless collector’s items now. For those lucky enough to still hold these genetics, it represents a direct link to a bygone era of cannabis history, offering a smoke experience that is completely unique compared to today's commercial market.

Growing Colombian Black: what to expect
As a hybrid, expect a moderate stretch after the flip (around 100%) — but watch the plant, not the label: phenotypes within Colombian Black can lean either direction. Whatever the listing says, the cut in YOUR tent is the ground truth: log feedings, readings, and photos, and let the trends — not the label — drive decisions.
