Lineage: Blueberry × Ruderalis, and that cross does exactly what you'd hope — it keeps the soft fruity-earthy character of the original Blueberry while stripping out the photoperiod dependency that trips up newer growers. THC sits in the 10–14% range with CBD climbing to 8% on some phenotypes, which puts this squarely in moderate-potency territory — useful if you're growing for daytime use or want something the whole circle can pass around without anyone tapping out early.

Autoflower timing means seed-to-harvest lands around 7–8 weeks regardless of your light schedule, and indoor runs regularly return 425–475 g/m² without much coaxing.
