The specs in one line: 18-25% THC, <1% CBD, 10-14 weeks flowering, 500-700g/m² reported. Best indoor or outdoor. moderate grow.

Lineage: Wifi OG × Biscotti, this Sensi Seeds cross sits at the heavier end of the indica spectrum and it shows in the structure — tight internodal spacing, a compact frame, and flowers that stack dense enough to push yields into the 500–700g/m² range under decent light. THC runs 18–25%, so expect a couch-pull that lasts; this isn't a quick, functional high. Flowering wraps in 10–14 weeks, which is on the longer side for an indica-leaning plant, but the tradeoff is bud density that justifies the wait. The smell is fuel-forward with a sweet citrus layer underneath — not subtle, so run a good carbon filter if odor control matters in your space.

Rated moderate difficulty, it handles both indoor and outdoor environments without major complaints, making it a reasonable step up for growers who've done a few photoperiod runs and want to push yield numbers.
