Blackberry Moonrocks Auto by Seeds66 is the autoflowering version of our feminized Blackberry Moonrocks – with the same intense berry spectrum, heavy resin production and strong THC levels, but in a fully automatic, shorter cycle. The genetics are based on Blue Moonrock (Blue Moon x BOG Bubble), Blackberry Kush and a selected Ruderalis that provides the autoflowering traits. The result is a compact, robust Seeds66 auto line that combines full flavour and high potency in a fast run.

Origin & Seeds66 Selection
Blackberry Moonrocks Auto keeps the core identity of the feminized version: deep berry flavour, strong resin production and a solid hybrid backbone. The added Ruderalis shortens the cycle and makes flowering fully automatic. In our internal tests in California, we selected phenotypes that stayed compact, showed strong colour expression and produced hard, dense buds within a clearly defined 8-week flowering window.
The goal was an autoflower that feels like a true Moonrocks line – aromatic, heavy, distinctive and clearly above average in potency. Only after this profile had been confirmed across several documented runs did we release the line as a Seeds66 auto.
Growth & Cultivation
Indoors, Blackberry Moonrocks Auto usually reaches up to 90 cm. It forms a strong main stem with solid side branches. Some plants develop wine-red to purple hues during mid to late flowering, especially under good climate conditions and strong light. The flowering time is around 8 weeks, which makes the cycle easy to integrate into everyday schedules.
Outdoors, it can be started from May and reaches up to 130 cm. Under good conditions, 100–200 g per plant are realistic. The strain prefers sunny, well-ventilated locations and shows strong resistance to mould, fungi and many common outdoor issues. With sufficient fresh air and moderate feeding, Blackberry Moonrocks Auto rewards growers with compact, heavy flowers.
Seeds66 Tip:
Plant Blackberry Moonrocks Auto directly into its final pot and keep a stable 20/4 light schedule. Light structural work on the side branches and good airflow help the heavy, resinous tops to ripen fully within the 8-week flowering time and develop their full berry spectrum.
Aroma & Terpenes
During cultivation, Blackberry Moonrocks Auto quickly fills the room with a sweet berry scent. The profile is reminiscent of blueberries, forest berries and dark blackberries, with a creamy sweetness in the background. When ground, the aroma becomes even denser – fruity, deep and slightly resinous.
The flavour is smooth, sweet and rounded. Thanks to its strong resin production, the strain is also very well suited for making concentrates and extracts.
Effects
With 24–28% THC, Blackberry Moonrocks Auto is one of the strongest autos in the Seeds66 catalog. The effect comes on clearly: body-focused, deeply relaxing and accompanied by a friendly, uplifting mental note. For beginners this can be too intense – the strain is aimed more at experienced users.
Most people choose it in the evening to unwind after long days or to support falling asleep. It is less suitable for tasks that require focus or long periods of concentration.
Seeds66 Philosophy
Blackberry Moonrocks Auto is a good indicator of how well a setup is tuned: light, climate and nutrient management directly influence structure, aroma and resin levels. At Seeds66, we only keep lines that show a clear, stable and recognizable performance across multiple grows – and this strain does exactly that.
In other words: We keep a Seeds66 line only if it consistently performs in real grows – not because it is trendy, but because it delivers.
