Taste Profile



This Session Garden strain guide article provides crowd sourced information about the Black Widow strain including the origins, THC content, appearance, effects & more.

The Lineage Of Black Widow

The Black Widow strain is a darker variant of the White Widow strain, its older sibling. Both of the Widow variants have been created by mixing the genetics of a South Indian Indica with a Brazilian Sativa to create a potent sativa dominant hybrid.

Black Widow History

The sativa dominant Black Widow hybrid has been around for a long time and has scooped a number of industry awards including Number One at the High Times Cannabis Cup back in 1995. Taking its name from the famous deadly spider, this hybrid won’t produce any deadly effects, but it does have a fascinating heritage.

This strain was created by Scott Blackey, a breeder who goes by the name of Shantibaba. As a renowned breeder, he has an association with Mr Nice Seeds and CBD Crew and also co-founded Amsterdam-based Greenhouse Seeds.

In 1994, Scott Blackey started to work in partnership with Arjan Roskam on a new line of cannabis seeds and the result of White Widow – a hybrid that won first place at the Cannabis Cup in 1995. When Blackey left Greenhouse Seeds three years later, he took the genetic knowledge of the White Widow strain along with him, but wasn’t allowed to take the strain’s name. Therefore, after founding Mr Nice Seeds with Howard Marks, Black Widow was released – a hybrid strain that is widely believed to actually be the original White Widow but with a different name. On the other hand, Roskam insists that the original White Widow wasn’t created by Blackey at all, but by Ingmar, a Dutch Breeder who then gave the generic knowledge to Greenhouse Seeds. That strain can now be found under the name “De Sjamaan Seeds”. The only way to know for certain if White Widow and Black Widow truly are the same is to try both!

How Is The Black Widow Strain Grown?

Even newcomers to growing will find the Black Widow strain relatively easy to grow as it is very resistant to pests, mold and mildew and will thrive either with soil or with a hydroponics setup. It can also be grown with the SCROG (Screen of Green) method for a higher yield.

Although Black Widow can be grown outdoors, it grows to more than 6 feet in height, so that needs to be borne in mind when deciding where to grow it. It also requires a sunny, warm climate. When grown outside, its harvest time is late September – early October and its yield is around 14oz per plant.

It’s best to grow Black Widow indoors since in an indoor grow environment it rarely grows to more than 3 feet in height. It will need plenty of light and will thrive especially when using the Sea of Green cultivation method with a flowering time of just 8 to 9 weeks and a yield of around 11-16oz per square meter. It is suitable for hydroponic growing methods as well as in soil, so this gives you plenty of versatility when it comes to growing options.

Be aware that during the last few weeks of the flowering period this strain will produce a strong aroma, so if discretion is important when growing your cannabis you will need to take steps to minimize the odor that this grow produces.

What Does Black Widow Look Like?

The bud of the Black Widow plant is incredibly dark. In fact, it can almost appear black – similar to the spider that it is named after! It also has lots of green in the buds together with orange hairs, and in the last few weeks of flowering and when harvest time is due, it becomes heavily covered in trichomes. This gives it a very appealing frosty look that is highly distinctive.

What Aroma Does Black Widow Have?

The Black Widow strain has a sweet yet skunky odor although there are some pine overtones. The flower has a fragrant aroma, and you’re sure to enjoy inhaling its scent. The overall effect is of an intoxicating mix of spice, sweetness, pine and fruit thanks to this strain’s interesting terpene and cannabinoid profile. Some people have even described the aroma of this strain as being a cross between fresh berries and newly dug garden soil!

What flavors can you expect from Black Widow?

As you might expect from the smell of this strain, the taste is skunky yet fruity. However, the aftertaste often comes as a surprise with its nutty flavour that really tantalizes your senses. Overall, this strain tastes just how it smells with an earthiness on the exhale that adds a little extra depth to the flavour.

What Effects can you expect from Black Widow?

Black Widow is an sativa dominant hybrid and has a high level of THC which can sometimes reach as high as 28%, so the powerful effects that it produces shouldn’t come as too much of a surprise. After a few hits, you’ll begin to experience an energetic uplift with a cerebral high that makes you feel talkative, more focused and euphoric. It’s important to be aware, though, that for some people couch-lock can be a side-effect of using too much of this strain.

Users report that there’s a fine balance between using the right amount of Black Widow to produce a fantastic high and accidentally overdoing it and ending up on the sofa for hours! This stain usually provides users with significant body relaxing benefits, but the intensity of the head high often leads users to fail to recognize how relaxed they are.

Unlike the deadly effects of the spider that this hybrid is named after, this strain produces effects that some users find very beneficial. Thanks to its indica content, this strain can increase focus, allowing you to function at higher levels. It also produces a cerebral intense high which boosts your mood. This makes it a popular choice for anyone who suffers from anxiety disorders, chronic stress or depression. These indica traits also produce sedative qualities that help users to sleep more soundly. It can also boost appetite. Since it’s known for inducing feelings of sleepiness and laziness, it is best saved for use in the evening.

As with any strain, Black Widow can produce some side-effects. As it is a very potent strain with THC levels that, in some cases, can be as high as 28%, it’s important to be aware that if you’re an inexperienced user or use too much, you could feel paranoid or anxious. Other common side-effects include dry mouth, dry eyes and dizziness. First time users may even feel panicked because of the strength of the effects. It’s therefore best used with caution, especially if you’re inexperienced with more powerful strains.
