Black Widow Feminized Seeds
Abundant resin is one of the defining traits of Black Widow. With good care, it develops buds heavily covered in trichomes, with a white, shiny appearance, while keeping that old-school character directly associated with the White Widow world.
Its lineage combines a Brazilian or South American sativa with a hybrid or sativa line from South India. This combination can be seen both in its sativa influence and in a traditional aromatic profile dominated by wood, spices, herbs, flowers and earth. Black Widow seeds in feminized form bring this classic concept into a format designed to produce female plants from seed and reduce the work involved in sexing.
How Black Widow Behaves During Cultivation
Our breeders work with it as a vigorous, resinous and productive photoperiod strain suitable for indoor and outdoor growing. Flowering takes around 60 days and can range from 8 to 10 weeks depending on the phenotype, selection and conditions. It is not an autoflower: indoors, it needs a change in the light cycle to start flowering.
Because of its sativa influence, it can stretch more than a compact indica. To keep it under control indoors, early training, height management and good ventilation are recommended. Outdoors, it benefits from good light, stable weather and moderate humidity at the end of flowering, especially to protect its dense, frosty flowers. Because of its growth behavior, it is better suited to growers with some experience.
Black Widow Effects
Black Widow delivers a medium-high to high-intensity effect. According to analyses from our breeders, its THC sits at around 20-22%, while CBD remains very low. The initial high can feel clear, euphoric, talkative and focused, accompanied by mental energy, creativity and a good mood.
Afterwards, a more noticeable body relaxation appears, especially at higher doses. This is not a strain that should be presented as mild, because it can feel intense even for users with some tolerance.
Its sensory profile deliberately avoids candy, banana or gas territory. Here, pepper, wood, earth, herbs and resin take the lead, with fresh pine and mild incense among the possible notes. It is an old-school flavor with a penetrating and recognizable presence.
