DTC99 by Brothers Grimm
Any time Brothers Grimm drops something, the old heads pay attention, and DTC99 (or DTC-99) is exactly why. This sativa-dominant beast is a cross of the legendary Durban Thai Highflyer and their iconic Cinderella 99. The Highflyer itself is an old-school Super Sativa Seed Club marvel—a mix of a sweet Thai female and a Durban Poison male. By hitting that with C99, Brothers Grimm essentially built a time machine back to the golden era of soaring, psychedelic sativas, but managed to wrestle the flowering time down to a very manageable 60 days. You just don't see that kind of speed paired with this specific type of high anymore.
In the garden, DTC99 is a serious structural powerhouse. Growers consistently talk about its incredibly sturdy branches and the massive, resin-dripping colas it produces. You don't have to support the branches like you do with a lot of lanky sativas because it builds these thick, rigid stalks. The terpene profile is totally unique, too. It pushes out this wild mix of musky incense, heavy black licorice, and a tart, almost sharp fruity sweetness. If you crack a jar of a properly cured pheno, it smells like an esoteric spice market mixed with a candy store.
But the real magic happens when you actually smoke it. The forum guys always call it "the working man’s weed" because the high is just perfectly functional. It hits you with this massive wave of creative, uplifting energy that clears the fog out of your head without tipping you into anxiety. You can smoke a joint of this with your morning coffee and actually go build a shed or write ten pages. It’s rare to find a strain that gives you such a pronounced cerebral rush while still keeping your feet planted firmly on the ground. Absolute legendary genetics.

Growing DTC99: what to expect
As a sativa-leaning plant, plan for a big stretch after the flip (often 100–200%) — flip earlier than feels natural and keep training options ready. Sativa-leaning plants also generally prefer a lighter feed than heavy indicas. Growers familiar with Durban Thai Highflyer or Cinderella 99 will recognize much of its behavior. 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.
