Our take

Black Widow is a sativa-dominant feminized strain bred by Scott Blakey (Shantibaba) from a Brazilian sativa and South Indian indica cross. At 25% THC, it delivers euphoric, happy, and relaxed effects with a complex aroma that layers earthy and skunky notes against fruity sweetness. It's best suited to growers with a few runs under their belt.

✓Yields up to 455 g/m² indoors from feminized, photoperiod plants that finish in roughly 63 days of flowering

✓Terpene profile of limonene, ocimene, and terpinolene produces a distinctly layered scent: sour, spicy, sweet, and skunky all at once

✓Solid natural resistance to common diseases gives intermediate growers a meaningful safety net during the grow

Growing notes

Black Widow suits indoor setups and outdoor gardens in sunny, continental, or Mediterranean climates, with an outdoor harvest arriving in October. Expect medium height plants and medium-to-large buds of moderate density. The 63-day indoor flower cycle is straightforward to manage, though dialing in feeding and environment will help maximize the yield potential. Rated intermediate — best if you've completed at least one previous grow.
