This Feminized photoperiod strain flowers in about 55 days. Expect bold effects, an expressive aroma, and a memorable flavor backed by gassy, sour, blackberry O.G. character. We think that combination gives Don Carlos a personality you remember long after the smoke clears.
Effects
Then the effects arrive. The breeder describes Don Carlos as extremely potent and ethereal, and its 20–24% THC supports that serious reputation. This is not a timid experience. The sensation can feel powerful, elevated, and almost dreamlike.
Think of the effect like a heavy bass line moving through the body while the mind drifts above the speakers. There is weight underneath and space overhead. That contrast fits the whole personality of Don Carlos.
Do you want something forgettable? Probably not. Don Carlos brings sour fruit, pine, fuel, and a potent cerebral atmosphere into one distinctive package. For shoppers drawn to expressive genetics and an Indica-dominant profile, it gives plenty of reasons to keep looking at the checkout button.
Flavor
Don Carlos starts with sour blackberry and quickly shows its darker side. The fruit feels ripe rather than sugary. Pine cuts through the sweetness, while a gassy O.G. edge keeps everything sharp and dirty in the best possible way.
The flavor moves across the palate like blackberry juice spilled over pine needles beside a hot engine. It is fruity, resinous, sour, and fuel-heavy. Each pull reveals another corner. We really like this strain because the profile has contrast instead of relying on one loud note.
