The DTC99 is a strain created by the Brothers Grimm. It is a cross of Durban Thai Highflyer female with a Brothers Grimm Cinderella 99 male. The Super Sativa Seed Club (SSSC) bred a Thai strain for four generations to stabilize its traits favoring indoor cultivation. SSSC's famous Durban Poison male was used to pollinate a particularly sweet Thai female from this fourth generation.
The hybrid was called "Durban Thai Highflier" by SSSC is has quite a reputation among Cannabis "Old-timers". They exhibited the best genes from both sides of their heritage, maturing early and remaining reasonably compact due to the Durban's influence.
True Thai weed is sickly sweet, but when crossed with the Durban, the hybrid took on a taste distinctly like black licorice. Bros Grimm decided to cross a particularly early-maturing female SSSC Durban Thai with a Cinderella 99 male. Expect a hybrid that is heavily Sativa-dominant, yet suited to indoor cultivation.
