Black Mountain Side Strain Lineage
The Black Mountain Side strain is a genetic variation of the legendary Girl Scout Cookies (GSC), crafted by crossing two iconic strains – Durban Poison and OG Kush.
Durban Poison contributes the uplifting, energetic sativa characteristics and that distinct herbal, earthy profile with citrus notes. OG Kush brings the relaxing body effects and adds complexity to the flavour profile with its signature Kush genetics and diesel aromatics.
Black Mountain Side Taste and Aroma
The moment you crack open the packaging of the Black Mountain Side strain,he aroma hits you with prominent citrus from the limonene, creating a refreshing, zesty quality. Underneath the lemon, there’s that classic diesel fuel sharpness that brings a pungent edge. The earthy, herbal base adds grounding depth.
When you actually combust the strain, the flavour experience is honestly impressive. You get an initial burst of lemony citrus and cake-like sweetness, followed by deep earthy herbal notes that punch your palate. The diesel character comes through on the mid-palate, and you’ll pick up nice spice notes on the exhale from the caryophyllene.
The smoke itself is smooth and doesn’t cause harsh coughing when consumed through proper methods.
Black Mountain Side Effects and High
The Black Mountain Side strain effects are honestly what make this flower stand out – it delivers a powerful mood-elevating experience that really makes its presence known from the first inhale.
Sitting at 26-30% THC with 3.6% terpenes, the Black Mountain Side strain has absolutely no issues getting you properly stoned. You really don’t need to smoke more than one or two bowls before you’re honestly quite high – this is definitely one of the more potent sativa strains available on the legal market.
After your first inhale, you’ll begin to feel your stress and anxieties melt away almost immediately. The high settles into a happy, giggly daze that elevates your mood and leaves you feeling genuinely content. There’s an uplifting, spacey quality to the head high that’s characteristic of good sativa genetics – your perception shifts in a blissful way that makes everything seem a bit more interesting.
What’s interesting about the Black Mountain Side strain is that despite being sativa-dominant, it offers a surprisingly relaxed experience. You won’t get racing thoughts or jittery energy – instead, it’s more of a blissful, elevated headspace that keeps you functional while feeling noticeably lifted.

Is EXKA’s Black Mountain Side a Good Value Strain?
Whether the Black Mountain Side strain represents good value honestly comes down to your tolerance level, but for most smokers it will be in the mid point.
At approximately $27.95-$36.95 for 3.5g ($7.96-$10.56/gram), this definitely sits in the premium price range. The 7g format offers slightly better value at around $36.95-$46, depending on the retailer. This isn’t budget weed by any means.
Bud Quality
EXKA has clearly taken pride in their product here, and the bud quality honestly shows it. The buds are dense, compact, and maintain good moisture content – they’re not overly dry or too sticky, hitting that sweet spot that makes for easy grinding and rolling.
Overall, the bag appeal is strong – these are buds that look as good as they smoke. For a strain grown in EXKA’s hybrid greenhouses rather than small-batch indoor, the quality is honestly exceptional.
Is EXKA’s Black Mountain Side a Strong Strain?
Yes, the Black Mountain Side strain is definitely a strong strain – there’s no getting around it. At 26-30% THC with 3.6% terpenes, this is legitimately high-potency cannabis that makes its presence known from the first inhale.
The Black Mountain Side strain is honestly one of the more potent sativa-dominant strains available on the legal market. The effects hit quickly and intensely, taking you on a 2-3 hour ride that’s powerful but manageable if you pace yourself.
Would I purchase This Strain Again?
The Black Mountain Side strain is objectively a great sativa-dominant hybrid – the potency is there, the flavour profile is complex and enjoyable, the bag appeal is excellent, and the effects are powerful and mood-elevating. Unlike last time, I had no anxiety during my consumption, so I would go ahead and say yes, i would buy the Black Mountain Side strain again.
