About Sugar Black Rose Auto

The way to plan Sugar Black Rose is backwards from the day you intend to cut, with 500 g/m2 per square metre indoors and 80 g/plant per plant outdoors as the figures you are working toward, at 18% THC. Count 60-70 days seed to harvest back from that date and you have your flip date. Most of the final weight lands between weeks 5 and 8, when calyxes stack fastest and trichome cover goes from patchy to complete. Outdoors in the Southern Hemisphere you want that fattening phase falling in February while the days are still long, which puts a late-March cut about right for most of the country.

The Aromatic Three

Leading with Myrcene, then Humulene, and Linalool underneath.

Difficulty: easy. In flower for 60-70 days seed to harvest. Stands above 70 cm, normally up to 1 m or higher. Indoors it returns 500 g/m2. Outdoors, 80 g/plant a plant.

Breeding Programme
Autoflower Stabilisation (F5) β€” ruderalis trait fixing
Stabilisation Notes β€” What This Means for Your Grow

Sugar Black Rose is our F5 autoflower line. Five rounds of selection have fixed both the autoflower trigger and the bud-to-leaf ratio the cultivar is known for. The recessive ruderalis trait demands this depth of work to express uniformly.

Breeding Goal

Lock the autoflower trait in Sugar Black Rose through five generations of selection.

Selection Focus

Chosen for indica vigour, compact bud formation and a reliable finish window.

Pollen / Mother Source

Royal King Genetics breeding facility β€” pollen from internally selected sibling males of the recurrent parent.
