Blackberry Gum© Feminized genetics: Bubble Gum × Blueberry

Bubble Gum X Blueberry → Blackberry Gum© Feminized

Blackberry Gum© Feminized is an unusual phenotype with a story that is very much ours. She appeared in a Barcelona cannabis club when a Bubble Gum male, the legendary strain with a gumball flavour, was crossed with a female Blueberry clone of very dark, almost black tones, one of the most famous blueberry profiles in the cannabis world.

That cross produced a very special fruity line, with buds and leaves that turn dark colours. Our breeders selected and stabilised it until it became what she is today: a reliable feminized strain that behaves the same way seed after seed, with the potency and resin production her parents guarantee.

What the plant looks like: purple hues, orange pistils and sugar-coated buds

From the moment she starts flowering, Blackberry Gum© Feminized demands attention. This plant doesn't just grow: she struts. She develops deep purple hues, vibrant orange pistils and a frosty coat of trichomes that makes her buds look dipped in sugar.

Although she is indica-dominant, she stretches hard during flowering and has wide internodal spacing, which helps airflow and later allows thick colas to form. Come harvest time she is a real show-off: heavy colas, striking colours and that resinous sheen that signals her potency.

Huge yields and dense buds, ideal for extractions

Blackberry Gum© Feminized yields well above average. Her buds are dense and heavy, and from early flowering through to harvest they are covered in shiny white trichomes that aren't just pretty: they also pack a huge amount of cannabinoids and terpenes.

That makes her top-tier genetics for anyone making hash, rosin, dry sift, bubble hash or live resin, with a very high extraction yield. Our breeders' notes sum it up nicely: beautiful white trichomes and excellent returns in any kind of extract.

Aroma and flavour: dark berries, bubblegum and candyfloss

FruityCandyDark berriesBubblegumCandyflossEarthy

During the grow, the plants smell of lemon peel and gas. Once cured, the buds give off a richer, sweeter perfume of dark forest berries, bubblegum and a hint of candyfloss. Break a bud open and you'll find an earthy base with layers of sweet-shop sweetness and a herbal, gassy edge. She is loud, sticky and will cling to your grinder, your fingers and your memory.

On the palate she is smooth, sweet and slightly wild. From the first draw you'll taste dark berries and bubblegum, followed by earthy, spicy hints and that touch of candyfloss that gives her a nostalgic feel.

Her terpene profile, analysed by Empiria Lab, exceeds 16,800 ppm and is led by myrcene (deep, musky and relaxing), caryophyllene (pepper and spice) and limonene (citrus), backed by humulene, geraniol and ocimene, which bring the fruity, floral and herbal nuances.

IndicaDominance
20%-26%THC

Blackberry Gum© effects: potency, euphoria and long-lasting relaxation

With 20-26% THC, Blackberry Gum© Feminized is one of the strongest strains in our catalogue. In Empiria Lab's analysis, grown under optimal conditions, she reached 25.42% THCA, the precursor of THC responsible for her intense psychoactivity. In other words: she hits hard.

Don't let her sweet-shop profile fool you. The effect starts in the head with a euphoric, cheerful and creative feeling, then slowly spreads through the body into deep relaxation and a very high, long-lasting sense of wellbeing. True to her indica dominance, she is ideal for the end of the day. Just go easy: overdo it and you can easily end up glued to the sofa.

How to grow Blackberry Gum© feminized seeds: indoors and outdoors

8 weeksFlowering
HugeYield
IntermediateExperience
Indoor/OutdoorGrow

Blackberry Gum© Feminized is forgiving, very productive and doesn't need much fuss, but like any top-shelf genetics, a few smart tweaks will make her shine. She wants light, room for her roots and plenty of water, and she responds brilliantly to training. She adapts to soil, coco or hydro; just keep the pH in check.

In an indoor grow, plan your height carefully, because she stretches eagerly. Outdoors she shows her full potential: she becomes a big, leafy plant that loves the sun and, interestingly, looks even better when the nights cool down at the end of flowering, which is when her purple tones really start to pop.

Tips for big harvests and sticky buds:

  • Watch the height: if you grow in a small tent or room, make sure you have enough height or start training her early with LST or topping.
  • Train her: SCROG, topping and light defoliation work wonders and help spread the light across all her colas.
  • Water yes, nutrients in moderation: she drinks like a champion, so give her big pots and regular watering, but don't overdo the nutrients: she isn't a heavy feeder.
  • Good airflow: her wide internodes help, but keep air moving well to avoid humidity problems in her thick colas.
  • Control the smell: in full bloom her aroma is very strong, so indoors a carbon filter is a must.

Is she the right choice for you?

✅ YES, if you're looking for...

  • A sweet flavour of dark berries, bubblegum and candyfloss over an earthy base
  • High potency (20-26% THC) with a euphoric effect that ends in relaxation
  • Huge harvests in just 8 weeks of flowering
  • Purple, resin-coated buds, ideal for hash and rosin
  • A plant that responds well to SCROG and topping

❌ NO, if...

  • You want a mild effect or have a low THC tolerance
  • You grow indoors with limited height and don't want to train the plant
  • You can't control odour in your grow space

Blackberry Gum© Feminized FAQ

How long does Blackberry Gum© Feminized take to flower?

Her flowering lasts around 8 weeks. The total length of the cycle depends on how long you keep the plant in veg: the longer the veg, the bigger the plant and the harvest.

How much THC does she have?

Between 20% and 26%. She delivers a very psychoactive, long-lasting effect, so she isn't the best choice if you're after something mild.

What does Blackberry Gum© Feminized smell like?

Living plants lean towards lemon and gas. Cured buds smell of red and dark berries mixed with bubblegum and an earthy base. It's a powerful aroma: indoors you'll need a carbon filter.

What is the best indoor setup for her?

Big pots, strong lights and room to stretch. For explosive early growth in veg, you can give her more than 20 hours of light a day. If height is limited, top her or train her early; SCROG works wonders.

Can I grow her outdoors?

Absolutely. Find a sunny spot and big pots with rich soil, because more room for the roots means more buds. In the northern hemisphere, harvest arrives in mid to late October depending on the climate, and the cool nights at the end of flowering will make her purple tones stand out.

Is she good for making extracts?

Yes, excellent. She produces a dense coating of trichomes and lots of resin, making her a favourite for hash and rosin. Harvest at peak ripeness and dry the buds in cool conditions to preserve all her terpenes.

The best in terms of taste and aroma.

A strong smoke, but the best thing about this strain is the aroma and the colors. A real change compared to the typical green skunks sold in my area. It reminds me of the early Kush buds, and it also has quite decent yields. I will definitely grow this one again.

Blackberry Gum Fem

Lovely genetics to grow, I never get many issues in a grow and this was no exception, she grew like a dream all the beans I popped grew almost identical, genetics appear to be very stable! They fed like monsters and were very forgiving, would show any issues with PH very quickly and recovered well! At week 8 a very small percentage of clear trichomes, pushed to week 9 and she was done! All in all great genetics, beautiful plants with subtle purples and pinks speckled throughout, caked in crystals and bursting with pistils! Sticky stinky nugs of wonder! 11/10
