Auto Blackberry Kush by Dutch Passion – Fast, High-Yielding Indica Auto with Purple Buds & Fruity Kush Aroma

Auto Blackberry Kush by Dutch Passion is a premium autoflowering indica that packs a punch in flavor, color, and effect, all in a compact 10–11 week cycle. This award-winning strain produces thick, resinous buds with a stunning purple hue and a rich, fruity-kush aroma that fills the room.

Are you still growing only green, bland autoflowers that lack character and power? You're missing out on the full sensory experience cannabis can offer.

Most autoflowers are bred for speed or yield, but sacrifice aroma, color, or potency. Sticking to basic strains means settling for average harvests, predictable effects, and zero visual appeal. You end up with forgettable buds and wasted grow space.

Auto Blackberry Kush changes the game. It’s a versatile powerhouse that thrives in any setup—indoors, outdoors, in soil or hydro—delivering vibrant purple buds, a complex terpene profile, and a deeply relaxing body high, all without needing a light cycle change. Whether you're chilling at home or prepping for a restful night, this strain adapts to your rhythm and delivers connoisseur-level quality every time.

Perfect for Indoor Grows: Compact Powerhouse with Explosive Aroma

When you grow Auto Blackberry Kush indoors, you get a compact, bushy plant that rarely exceeds 0.80–1.10 m (2.62–3.61 ft), making it ideal for small tents or stealth setups. Under 18–20 hours of light, it grows vigorously, developing a thick main cola and dense side branches perfect for SOG (Sea of Green).

The real magic happens in late flowering: the buds swell with resin and deepen into rich purple and violet tones, especially when night temps drop. The aroma becomes intense—think fresh blackberries, pine, and a hint of diesel—so a carbon filter like the Seedfinder series is a smart addition if discretion is key.

Keep humidity below 50% in flowering to avoid mold, and use a small oscillating fan to strengthen stems and improve airflow. You’ll be rewarded with up to 450 g/m² (1.6 oz/ft²) of top-shelf bud that tastes as good as it looks.

Outdoor & Balcony Friendly: Fast, Resilient, and Discreet

Outdoors, Auto Blackberry Kush shines in sunny, dry climates, reaching up to 1.10 m (3.61 ft) and producing 50–100 g/plant (1.76–3.53 oz/plant). Its fast 10–11 week cycle lets you fit multiple grows in a single season, even in northern latitudes.

Plant it in a 20L pot with well-draining soil and place it in full sun. The plant’s natural resistance to pests and cold makes it a great choice for balconies or patios. Just avoid rainy periods—compact buds can be prone to bud rot in high humidity.

For stronger roots and better nutrient uptake, consider starting with Root It 150ml – Rooting gel, which helps seedlings establish fast and stay healthy through the grow.

How to Choose the Best Setup for You

Whether you're a stealth grower, a balcony enthusiast, or a connoisseur chasing flavor and color, Auto Blackberry Kush fits your style. Here’s how to pick your path:

• If you’re short on space or want maximum discretion, go indoor with a 60x60x160 cm tent and LED lighting.
• If you love natural sunlight and low maintenance, grow it on a sunny balcony in a 20L fabric pot.
• If you’re after the deepest purple colors, lower night temps during flowering—this strain reacts strongly to cold.
• If you want bigger yields, use a 25L pot and a powerful LED like the Holographic Series 1.
• If you’re new to growing, this is one of the easiest high-quality autos to master.

How to grow Auto Blackberry Kush

Quick overview: Dutch Passion’s Auto Blackberry Kush is an easy-to-grow, indica-dominant autoflower ready in 10–11 weeks. Ideal for indoor tents or sunny balconies, it thrives in soil, coco or hydro.

Safe start: Germinate seeds at 22–25 °C with high humidity. Transplant once the taproot is ~1 cm long. For faster rooting and less stress, Root It 150ml – Rooting gel boosts early root development.

Stable seedling: Keep RH at 60–70% and temperature at 22–26 °C. Water lightly and use airy soil. Adding MYCOPLANT enhances root zone health and nutrient uptake.

Directed growth: Maintain 18–20 h light. Use a 20L pot and avoid aggressive pruning. Apply LST gently to open up the canopy. Keep pH at 6.0–6.5 (soil) or 5.8–6.2 (coco).

Flowering by stages: In weeks 4–5, pre-flower stretch begins. Reduce RH to 50%. In mid-flower, support heavy colas if needed. In late flower, lower RH to 40–50% and flush 7–10 days before harvest.

Harvest, drying and curing: Harvest when trichomes are mostly milky with some amber for a relaxing high. Dry at 18–22 °C and 50–60% RH for 10–14 days, then cure in jars for 2–4 weeks for maximum flavor.

Frequently Asked Questions

How can I make Auto Blackberry Kush turn more purple?

Lower night temperatures during flowering (by 5–10 °C) triggers anthocyanin production, enhancing purple and violet hues in the leaves and buds. This strain is especially responsive to cold stress.

Does it smell strong during flowering?

Yes, it has a high odor profile with fruity, earthy and diesel notes. Use a carbon filter like Seedfinder to control smell, especially in indoor grows.

Can I grow it in a small tent?

Absolutely. It stays compact (0.75–1.10 m) and responds well to LST. A 60x60x160 cm tent with a 200W LED is more than enough for 1–2 plants.

Is it mold-resistant?

It has moderate resistance, but dense buds can be prone to botrytis in high humidity. Ensure good airflow and keep RH below 50% in flowering.

What’s the best nutrient schedule?

Use a mild, balanced feed. Avoid overfeeding—autos are sensitive. A simple grow-bloom kit like Advanced Nutrients Cultivator Series Kit works perfectly.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown Auto Blackberry Kush three times now—once indoors under LEDs, once on my balcony, and once in a greenhouse. My favorite? The balcony grow. There’s something magical about watching those buds turn deep purple under natural sunlight, especially when the nights get cool.

I used 20L fabric pots and Plagron soil, with a little MYCOPLANT at the start. The smell was intense by week 8—like blackberry jam and pine resin—so I kept the windows closed at night.

Harvest came at week 10.5. I dried slowly and cured for three weeks. The high is no joke: full-body relaxation, perfect for crashing after a long day. I’ve recommended it to friends who want quality without the hassle. If you’re looking for an auto that looks, smells and tastes like premium craft weed, this is it.
