Genetics: A Triple-Berry Build
Our breeders started with the photoperiod hybrid of Bubble Gum and Blueberry — two of marijuana’s most quoted terpene profiles — then crossed it with Blackberry Auto to lock in the autoflowering gene and stabilize Blueberry’s standout traits. The result is a Classics-range autoflower with photoperiod-grade aroma, predictable structure, and bulletproof timing.
Growing Blackberry Gum© Autoflower
A short, branchy plant that grows vigorously in its first weeks, then keeps stretching modestly through flower. Compact lateral colas form alongside a chunky apical bud, and toward the end of the cycle she often turns deep purple — a bonus for growers who care as much about looks as yield.
👉 Top tip: Sow Blackberry Gum© Auto directly into her final pot. Autos hate transplant stress — skip it and you’ll keep her on her 11-week schedule with no setbacks.
