Effects & Usage



Black Widow is a sativa-dominant hybrid strain born from a meticulous cross between a Brazilian Sativa landrace and a resin-heavy South Indian Indica. With a THC content ranging from 18% to a staggering 28% THC, it generates a dynamic cerebral high that is mentally stimulating and relaxing at the same time.


With a THC content of up to 28%, Black Widow acts quickly and powerfully, just like its namesake’s venom. Within moments of consumption, the strain envelops the user in a wave of mental invigoration, courtesy of the stimulating terpinolene. This quickly cascades into euphoria and productivity. As the strain removes stress and all mental obstacles, it will instantly help you focus much better. Therefore, Black Widow can be a perfect choice whenever you need to increase your efficiency. However, it is all about balance; midway through the high, you will also start noticing how deeply relaxed your body has become. Use a bit too much of Black Widow, or come across a particularly potent batch – and you will likely find yourself couch-locked, too relaxed to care about anything. For this reason, it is best to keep it to afternoons or evenings. As a well-rounded, versatile strain, Black Widow will be great to enjoy on your own as well as with others.

Black Widow’s balanced profile makes it an excellent remedy for various ailments. With substantial amounts of CBG and CBD (at 1%), the strain can help with stress and pain. It may be helpful for other conditions, such as muscle spasms, headaches, chronic pain, and arthritis.

Depression, mental fatigue and ADHD symptoms may also be relieved with the help of uplifting terpenes: limonene and ocimene. Reportedly, even patients with conditions such as PTSD may find some solace in Black Widow.

Side effects

Common side effects of Black Widow consumption include dry mouth and eyes, easily mitigated by staying hydrated. However, this is not a strain for newbies or those with low THC tolerance, as they may experience some paranoia or anxiety. Therefore, starting with a small dose and gradually increasing consumption as needed is advisable to avoid unpleasant adverse reactions.

Taste & Smell


Black Widow boasts a spectacle of colours, with deep dark purple hues intertwined with green, contrasted by the orange pistils and tiny sparkling trichome crystals. The strain also smells enjoyable – a mix of sweet and skunky fragrances with piney notes. You will indeed taste the skunk and pine as soon as you take the first puff. Expect some fruity, nutty finish underneath them, overall making for a very pleasant, smooth smoke.



Black Widow is the creation of the legendary Shantibaba, also responsible for its more famous sibling, White Widow. Legend has it that he could no longer use the White Widow name after he left the Amsterdam Green House Seeds. Therefore, he recreated the strain using the same parents, two landraces: a South Indian indica and a Brazilian sativa.

Likely the Black Widow we know today is just a darker phenotype of its older sister.

Growing conditions

Black Widow is a perfect strain for first-time growers because of how low-maintenance it is. It is resistant to pests, mildew and moulds and will grow in just about any environment – as long as it is kept in plenty of sunshine. Rain could lower the yields, so it is best to keep the plants sheltered.

The plant can reach an average height of around 1 metre indoors but even up to 2 metres outdoors. Within 8 to 9 weeks, you can expect to harvest 350 to 450 grams for indoor plantations and 300 to 400 grams per outdoor plant.
