About Seattle Blue Feminised
Days 1 to 14, seed to fourth node: Expect Seattle Blue 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 65: The 44/56 character becomes obvious here. Caryophyllene usually shows in week three and strengthens from there, with trichome cover visible without a loupe from about week five. Indoor yield: up to 400 g/m2. Height: 90-120 cm. Medium. Tested at 27% THC. Difficulty: beginner to intermediate.
The Aromatic Three
