About Sweet Berry Auto
Days 1 to 14, seed to fourth node: Expect Sweet Berry to crack in roughly 48 hours on damp paper towel and to break soil by day three. Growth is even and unhurried — four solid nodes by day 14, spaced somewhere between the two parent types. Damping off is rare if you hold near 70% humidity through this stage.
Weeks 3 to 6, building the frame: One top at node four and a light tie-down is all it asks for. Six leaders and an even canopy across roughly 70 x 70 cm, then it is ready to flip.
Bloom, weeks 1 to 60: The 38/62 character becomes obvious here. Limonene usually shows in week three and strengthens from there, with trichome cover visible without a loupe from about week five. Indoor yield: up to 250 g/m2. Height: 80–120 cm. Tested at 19% THC. Difficulty: easy.
The Aromatic Three
Leading with Limonene, then Caryophyllene, and Linalool underneath.
Difficulty: easy. In flower for 50-60 days. Stands 80–120 cm. Indoors it returns up to 250 g/m2. Outdoors, up to 400 g/plant a plant.

Sweet Berry Auto — Breeder Information
Royal King GeneticsRecreated and stabilised by Royal King Genetics, the breeding team behind this catalogue. Seed lots are germination-tested before they ship. More on the breeding process and about page.
Sweet Berry is our F5 autoflower line. Five rounds of selection have fixed both the autoflower trigger and the flavour saturation the cultivar is known for. The recessive ruderalis trait demands this depth of work to express uniformly.
Lock the autoflower trait in Sweet Berry through five generations of selection.
Chosen for terpene profile, vigour, structure and finish-time consistency.
