What is the Poison Berry strain?
Poison Berry Auto is a feminized autoflowering hybrid that crosses Blueberry with Durban Poison and adds ruderalis so the plants flower without a light change. Crop King Seeds and the seed banks that carry the same line list it as a balanced hybrid with 18–24% THC and about 7% CBD, harvested about 8 to 9 weeks into its cycle. A different, unrelated Poison Berry from Mr H Genetics (Berry Grant × Green Poison) also exists, but that one is a regular photoperiod indica, not this autoflower.
Seed bank specs list about 7% CBD next to 18–24% THC, which is rare for a berry hybrid; no published lab test backs the figure yet.

Where does the Poison Berry strain come from?
Poison Berry Auto comes from Blueberry crossed with Durban Poison, with ruderalis added to make the plants autoflower. Crop King Seeds lists the cross as Blueberry × Durban Poison × Ruderalis, and Seeds of Ganja traces the grandparents back to Afghani, Purple Thai and Thai lines, which matches the usual family tree of Blueberry. The seller does not name the person who made the cross or the year it was released.
Blueberry supplies the sweet fruit smell and the compact, dense flowers; Durban Poison brings its sativa drive and a spicy, herbal edge. The ruderalis share is what lets Poison Berry Auto flower on age instead of day length, and it is also why this version runs smaller and faster than a photoperiod Blueberry or Durban Poison.
Is Poison Berry Auto the same as Mr H Genetics' Poison Berry?
No. SeedFinder lists a separate Poison Berry from Mr H Genetics, bred from a Berry Grant male and a Green Poison female. That strain is a mostly indica photoperiod plant that flowers in about 70 days and has never been sold as feminized seed. The autoflower sold here shares only the name.
One more name clash: a few shops sell a "Poison Berry" made from Sherbert and Agent Orange. Check the genetics line on any listing before comparing grow reports.
What does Poison Berry taste like, and how does it feel?
Aroma and flavor
Poison Berry Auto tastes of sweet blueberry first, then turns woody and herbal with a peppery finish from its Durban Poison side.
- Blueberry
- Sweet fruit
- Herbal
- Wood
- Pepper
Terpenes
- Limonene
- Citrus lift behind the berry
- Myrcene
- Earthy, ripe-fruit base
- Terpinolene
- Fresh, floral and slightly piney
- Ocimene
- Sweet, green herbal note
Poison Berry's terpene list comes from seller specs, not a published lab profile, so read it as a guide.
Reported effects
Poison Berry Auto is described as calming at first, followed by a happy, creative lift that stays fairly clear-headed. Sellers call the mix balanced: a relaxed body from the Blueberry side with some of Durban Poison's mental energy.
- Relaxed
- Happy
- Creative
- Uplifted
- Energetic
Poison Berry Auto has few published user reports, but dry mouth and dry eyes are the usual complaints with Blueberry and Durban Poison crosses, and strong doses can feel racy.
These Poison Berry effects come from seller descriptions and buyer comments; no large review base exists yet. Everyone responds differently, and nothing here is medical advice.
How do you grow Poison Berry seeds?
Poison Berry seeds grow into a moderate-difficulty autoflower: sow straight into the final pot, give 18 or more hours of light, train gently in the first weeks, and keep humidity low as the berry-scented buds fill out.
- Germinate3–7 days
Plant the sprouted Poison Berry seed in its final container so the short auto cycle is not interrupted by transplant shock.
- Early growthWeeks 1–4
Poison Berry Auto builds its frame fast; bend the main stem with soft ties around week 3 to spread the tops.
- FlowerFrom about week 4
Flowers start on their own with no 12/12 needed. Feed lightly and watch airflow around the dense Blueberry-style colas.
- HarvestAbout 8–11 weeks from seed
Go by trichomes, not the calendar: harvest when most heads look cloudy with a few amber.
Grow tips for Poison Berry
- Watch for mold. Crop King's own notes say Poison Berry buds can be sensitive to moisture, so keep relative humidity near 40–45% in late flower and thin crowded inner leaves.
- Skip topping after week 3. An autoflower cannot regrow lost time. If you top Poison Berry at all, do it once, early, or rely on LST instead.
- Give it full light hours. Because Poison Berry Auto flowers on age, you can run 18/6 or 20/4 from seed to harvest for more growth.
- Plan the timeline loosely. The 8–9 week figure in listings is short for a Blueberry and Durban Poison cross, so leave room for a week or two more.
- Use the summer outdoors. Outdoors, Poison Berry Auto does best in warm, sunny weather; a spring sowing can finish by midsummer, before damp autumn nights.
Is Poison Berry the right strain for you?
Great pick if you
- Want a quick autoflower that needs no light-schedule change
- Like sweet berry flavor with a woody, peppery edge
- Prefer a balanced, mellow-then-creative effect
- Grow in a small tent or want more than one outdoor harvest a year
Think twice if you
- Need lab-confirmed THC and CBD figures before you buy
- Grow in a damp climate without dehumidifiers
- Want a pure, racy Durban Poison sativa
- Prefer to clone a mother plant (autos don't suit that)
Poison Berry strain FAQ
Is Poison Berry indica or sativa?
Poison Berry Auto is listed as a balanced hybrid. Its Blueberry parent leans indica and its Durban Poison parent is a sativa, and ruderalis was added for autoflowering. No seller gives an exact indica to sativa percentage.
What are the genetics of Poison Berry Auto?
Crop King Seeds and the shops selling the same line list Poison Berry Auto as Blueberry × Durban Poison × Ruderalis. The grandparents trace to Afghani, Purple Thai and Thai lines through Blueberry. The breeder of the cross is not named.
How long does Poison Berry Auto take to grow?
Listings give Poison Berry Auto a cycle of about 8 to 9 weeks. They don't say whether that is counted from seed or from the first flowers, so most growers plan on roughly 9 to 11 weeks from seed and harvest by trichome color.
How much THC and CBD does Poison Berry have?
Seed bank specs list Poison Berry Auto at 18–24% THC and about 7% CBD. That CBD figure is high for a THC-rich berry hybrid and has not been confirmed by a published lab test, so read it as a seller claim.
What does Poison Berry taste like?
Poison Berry tastes of sweet blueberry and ripe fruit up front, with herbal, woody and peppery notes on the finish. Sellers list limonene, myrcene, terpinolene and ocimene as its main terpenes.
How tall does Poison Berry Auto grow?
Sellers list Poison Berry Auto as small indoors (under 4 ft, about 1.2 m) and medium outdoors. Like most autoflowers, it usually stays compact, and height depends heavily on pot size, light and the first weeks of growth.
Is Poison Berry related to Mr H Genetics' Poison Berry?
No. Mr H Genetics' Poison Berry is a regular photoperiod indica bred from Berry Grant and Green Poison. Poison Berry Auto is a different cross, Blueberry × Durban Poison × Ruderalis, that only shares the name.
How much does Poison Berry Auto yield?
Seller specs list Poison Berry Auto at 360–530 g/m² indoors and 450–700 g per plant outdoors. These are optimistic best-case figures; real yields for an autoflower depend on light intensity, pot size and how well the first month goes.
