Figures below come from our own seed-lot testing rather than breeder marketing, taken from a single batch tested 2026-09-19 on 250 seeds.
About Diablo Auto
Days 1 to 14, seed to fourth node: Expect Diablo 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 40/50 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 200 g/m2. Height: Short. Tested at 18% THC. Difficulty: intermediate.
The Aromatic Three
Leading with Limonene, then Caryophyllene, and Linalool underneath.
Difficulty: intermediate. In flower for 50-60 days. Stands Short. Indoors it returns up to 200 g/m2. Outdoors, up to 200 g/plant a plant.
