Black Widow Seeds

The key difference comes down to what you're buying them for. Feminized seeds are the most widely available format — stocked by Homegrown Cannabis Co, ILGM, and Weed Seeds USA — and deliver the full 400–500g/m² indoor yield potential of this strain. Regular seeds, available exclusively through Seedsman, are the right choice if you're working with Black Widow's Brazilian Sativa x South-Indian Indica genetics for breeding purposes. Autoflower seeds from Crop King Seeds complete the 8–10 week cycle from seed without requiring a light schedule change, but yield figures are lower than the photoperiod versions. Your buying decision should start with format, then compare pricing across the seedbanks that carry your preferred type.

Black Widow seeds carry a verified THC range of 15–28%, which is one of the wider potency windows you'll see on a single strain. That spread reflects genuine genetic variation between phenotypes rather than inconsistent testing. If maximum potency is your priority, it's worth comparing lab-tested results across seedbanks — specifically between Homegrown Cannabis Co, ILGM, and Crop King Seeds — as different breeders may have selected for different ends of that range. Buyers specifically looking for high-THC seeds should note that Black Widow's upper range of 28% puts it in elite company, particularly for a strain rated beginner-friendly.

From a seed-buying perspective, Black Widow is one of the more beginner-accessible high-THC strains on the market. Its beginner difficulty rating means you're not paying a premium for a strain that will punish inexperience — which is often the hidden cost of buying potent, complex genetics. The 8–9 week flowering time (or 8–10 weeks from seed for the autoflower version) is also manageable for first-time buyers planning their first full cycle. If you're a newer grower comparing Black Widow against other beginner-rated options, the combination of high-yield seeds potential and a forgiving growth profile makes it a strong first purchase.

You can buy Black Widow seeds from five seedbanks: Homegrown Cannabis Co, ILGM, Weed Seeds USA, Seedsman, and Crop King Seeds. Feminized seeds are available from Homegrown Cannabis Co, ILGM, and Weed Seeds USA — compare pack sizes and per-seed pricing across all three before ordering, as promotions vary. Seedsman is the sole source for regular seeds if you need that format. Crop King Seeds carries the autoflower version exclusively. All five seedbanks ship discreetly, and several offer cryptocurrency payment discounts. For the best value on feminized seeds specifically, ILGM and Homegrown Cannabis Co are the two most competitive options to evaluate side by side.
