Black Widow Seeds

Black Widow


The Controversial Origin of a Legend?

Black Widow is said to be the original parentage of the strain that would become famous as White Widow. A longstanding controversy surrounds who truly created it and which lineage is the most authentic. What’s certain is that Mr. Nice Seedbank (a.k.a. Shantibaba) delivers a superb cross of Brazilian Sativa and South Indian hybrid in Black Widow.

With around 10 weeks of flowering, it reveals heavy resin production for dense, crystal-coated buds. As regular seeds, you can expect roughly a 50:50 split of male and female plants—perfect for anyone interested in breeding or seed production. Fruity and slightly skunky flavors pave the way for a heady, potent effect that also offers a soothing calm. A true gem for connoisseurs and hobby breeders alike.

Autoflower


Autoflowering cannabis strains are hybrids with Ruderalis genetics that bloom independently of light cycles. This trait evolved as an adaptation to northern climates with short summers. Unlike photoperiod strains, which require specific light cycles to flower, autoflowers begin flowering automatically after a growth period of approximately 2 to 4 weeks, depending on the genetics. Their short lifecycle—usually around 70 to 80 days—makes them ideal for quick harvests, whether grown indoors or outdoors.

Autoflowers are popular among beginners and experienced growers alike due to their simplicity and ability to produce multiple harvests in a year. High-quality autoflowers are often resilient to cold, pests, and mold, though breeding quality plays a crucial role. Poorly bred autoflowers may be more prone to mold or stress-related issues. Their compact size (typically 75–100 cm) makes them well-suited for small spaces or discreet setups. Additionally, in regions with unpredictable weather or short summers, their rapid lifecycle allows them to bypass extreme conditions before harvest.

Photoperiod


Photoperiod cannabis strains require specific light cycles to trigger their flowering phase. In nature, this phase begins when days grow shorter—typically in late summer or autumn. The process is regulated by light-sensitive proteins called phytochromes. In indoor cultivation, growers replicate these conditions by adjusting the daily light schedule from 18 hours of light (vegetative phase) to usually 12 hours of light and darkness (flowering phase).

Photoperiod strains often offer greater variety and potency than autoflowers, as their genetic pool is broader and not limited by Ruderalis genetics. However, some autoflowers are beginning to close the gap in both potency and diversity. These strains are favored by experienced growers because they allow precise control over growth, size, yield, and cannabinoid profiles. However, they require meticulous management of light cycles, temperature, humidity, and nutrients to achieve optimal results.
