About Platinum GSC Feminised

Days 1 to 14, seed to fourth node: Expect Platinum GSC to crack in roughly 48 hours on damp paper towel and to break soil by day three. Growth is even and unhurried β€” 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 60/40 character becomes obvious here. Myrcene usually shows in week three and strengthens from there, with trichome cover visible without a loupe from about week five. Indoor yield: 350-400 g/m2. Height: up to 120 cm. Tested at 23% THC. Difficulty: intermediate.

The Aromatic Three

Leading with Myrcene, then Limonene, and Pinene underneath.

Difficulty: intermediate. In flower for 8-9 weeks. Stands up to 120 cm. Indoors it returns 350-400 g/m2. Outdoors, 1200-2000 g/plant a plant.
