About Sour Tsunami Feminised
Days 1 to 14, seed to fourth node: Expect Sour Tsunami 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 9: The 40/60 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: 350 - 450 g/m². Height: Tall. Tested at 7% THC. Difficulty: easy.
The Aromatic Three
Leading with Limonene, then Caryophyllene, and Linalool underneath.
Difficulty: easy. In flower for 9 weeks. Stands Tall. Indoors it returns 350 - 450 g/m². Outdoors, 450 - 600 g/plant a plant.
