Blackberry Crack by Sterquiliniis
Blackberry Crack from Sterquiliniis Seed Supply is one of those underground auto-flowering gems that really turns heads when it starts stacking late in flower. Sterquiliniis took their in-house Green Crush and slammed it into an unnamed C-4 Matic to create this ruderalis/sativa hybrid. The result is a quick-finishing auto that doesn't compromise on yield or bag appeal. Taking only about 63 days from seed to harvest indoors, it’s a perfect run for guys running perpetual autos who need quick turnarounds without sacrificing quality.
What really gets people talking on the forums is the color and the nose on this plant. As she fades, the buds turn a deep, rich purple that looks almost black under the grow lights, completely caked in a thick layer of sticky resin. The smell is wild—it’s got this intense fruity funk that growers describe as "spoiled blackberries." It’s sharp, sweet, and a little bit fermented, making it an absolute treat for anyone tired of the usual cookie or gas profiles dominating the scene.
Sterquiliniis knew they had a winner here because they immediately started using Blackberry Crack as a breeding stud for other wild crosses. You'll see its DNA in strains like SnozzBerry, Hurricane Punch, and Blackberry Newtons. It passes down that incredible color and the funky berry terps consistently. If you're flipping autos and want something that brings heavy frost, crazy colors, and a smell that will stink up your whole house, Blackberry Crack is a mandatory run.

Growing Blackberry Crack: 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 Green Crush or C4-Matic 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.
