Black Runtz Feminized Cannabis Seeds
Black Runtz Feminized Cannabis Seeds are a flavor-forward, high-potency option for growers who want dense buds, loud terpenes, and a smooth, relaxing finish. Black Runtz is commonly described as an indica-leaning hybrid from the Runtz family, most often reported as Zkittlez × Gelato genetics, delivering sticky flowers with serious bag appeal and a dessert-style profile.
With a THC content of 19–29% and typically low CBD, Black Runtz is known for a happy, euphoric lift that transitions into a deeper body calm as the session settles in (dose-dependent). It’s a great pick for customers who want strong effects without sacrificing flavor.
Flavor, Aroma & Overall Experience
Black Runtz is loved for its candy-like sweetness. Expect a terp profile that leans sweet, fruity, and creamy with notes of berry and citrus, backed by an earthy base and a light gassy/spicy edge on the finish.
Effects are often described as euphoric, uplifting, and mood-boosting at first, followed by a relaxing, soothing body feel that can become heavier at higher doses.
Why Grow Black Runtz Feminized?
- High potency – a strong THC range for experienced customers.
- Dessert terps – sweet candy-fruit flavor with an earthy-gas finish.
- Dense, resinous buds – sticky flowers and excellent bag appeal.
- Feminized reliability – efficient canopy planning without worrying about males.
Growing Black Runtz (Indoor / Outdoor / Greenhouse)
Black Runtz is a photoperiod feminized strain with a commonly listed indoor flowering time of about 8–9 weeks. Outdoors, many growers plan harvest for early to mid-October depending on climate and finishing conditions.
- Canopy management: Light topping + LST helps open bud sites and improve airflow through dense flowers.
- Humidity control: Keep airflow strong in mid/late flower to support tight bud formation and resin production.
- Terp quality tip: Avoid overfeeding late flower—steady nutrition and stable conditions help preserve flavor.

I just grew a 10 foot monster so far this year! Thanks to QCS and their great genetics. This is my second year growing Quebec white and three other plants. All have performed as advertised. I’m definitely going back to them for some new seeds for next year. Thanks to QCS, and a great growing year and I’m totally happy!

I am at week five in flower with the Black Runtz, she clones extremely well and the trichomes are mind boggling! Love the work you've done folks, I look forwards to try more of your strains in the future.

Growing outdoors The plant lasts over 9 weeks from flowering - it's October 20 and the plant isn't quite ready yet. The genetics are very resistant as such, big plants, many heads not very big. No mold or bud rot. No stress sign. Description says: visually attractive head they are normal with brown pistillas .

Hey, just popped a black runtz, so far so good, the two different potential THC percentages, is that from using CO2 enrichment?
ADMIN: Thanks for that. I had not noticed. That was a mistake on our part. the correct is THC 30% and 32%
