Ultra G13 Auto

Ultra G13 is a limited-edition F1 feminised autoflower from Mephisto Genetics, combining HubbaBubbaHaze with Do-si-delirium. It is a mostly sativa hybrid (35% indica / 65% sativa) intended for straightforward cultivation with a quick seed-to-harvest cycle. Plants typically finish 70–80 days from sprout and reach 70–100 cm, developing large, branching structures and notable resin coverage. Reported aromas lean citrus with piney and spicy elements. Effects are described by the breeder as an upbeat, cerebral lift that can bring giggles and energetic motivation. Mephisto publishes COAs for this release; third‑party summaries place THC roughly in the high‑teens to mid‑20s. Ultra G13 was part of the September 2024 Do-si-delirium F1 drop and is offered exclusively in 5‑seed packs.
