Blackberry Kush Auto FAQ

It blends deep berry flavor with a tendency for purple and blue hues in late flower — offering high visual impact and sweet, earthy aroma in a fast, compact grow.

Expect a fruity-sweet aroma that intensifies into rich notes of ripe blackberry, earthy spice, and a touch of diesel in the final weeks of bloom.

Extremely. Blackberry Kush Auto produces dense, trichome-covered flowers that glisten with resin — especially when grown under strong lighting with stable conditions.

When trichomes are mostly cloudy with some amber, pistils are dark and curled in, and the scent is rich and pungent — your plant is likely ready.

Yes, our Blackberry Kush Auto seeds are tested in an outside laboratory and we provide the Certificate of Analysis on every product page.

Dense, frost-covered buds often show deep greens, blues, or purples depending on environmental conditions. It’s highly photogenic and visually rich.

Yes. The sweet berry aroma becomes bold and noticeable by week 7 or 8. Indoor growers should plan for odor control.

It’s ideal for home growers who prioritize flavor and aesthetics, especially those with limited space or who want multiple harvests per year.

Blackberry Kush Auto usually finishes in 9–10 weeks. With optimal care, some phenos may be ready as early as day 63.

Yes, it’s highly resinous, making it a great candidate for those interested in extracts or simply sticky, trichome-rich flower.

No. It flowers based on age, not light cycle. Most growers keep lights on 18–20 hours per day throughout the full grow.

Yes. Its short lifecycle makes it perfect for 2–3 outdoor runs per season in warm climates or for one early harvest in cooler areas.

Definitely. It’s compact, low-maintenance, and fairly resistant to stress — great for beginners who want strong results with minimal fuss.

No. Autoflowers generally don’t have time to recover from topping. Instead, use gentle low-stress training (LST) to open the canopy.

Indoors, expect 300–400g/m². Outdoors, well-cared-for plants can yield 50–90g each, depending on sunlight and container size.

Use a 3–5 gallon (11–19L) container from the start. Autos perform best when not transplanted, so plant directly into the final pot.

Cooler nighttime temperatures in late flower (16–20°C) can trigger purple or blue hues in the buds and sugar leaves.

Keep temps between 21–26°C (70–78°F) and reduce RH to 40–50% in flower to avoid mold and promote resin production.

Start feeding bloom nutrients around week 3 or when pre-flowers appear. Begin lightly and increase as the plant fills out.

Only light defoliation is needed. Clear any leaves blocking key bud sites or airflow but avoid heavy pruning, which can slow autos down.

Hemp seeds are legal in the US provided they contain less than 0.3% THC, as specified by the 2018 Farm Bill. However, it is your responsibility to research and comply with local laws and regulations before ordering.
