About Mexican Haze Feminised
Days 1 to 14, seed to fourth node: Expect Mexican Haze to crack in roughly 48 hours on damp paper towel and to break soil by day three. Early growth runs upward quickly, narrow first leaves already reaching. Look for five nodes by day 14 with obvious gaps between them, which is the sativa pattern showing early. Damping off is rare if you hold near 70% humidity through this stage.
Weeks 3 to 6, building the frame: This is the point where it tries to get away from you. Start low-stress training in week three, bend the main stem over at 90 degrees in week four, and the secondaries will draw level for a flat canopy by week six without topping at all.
Bloom, weeks 1 to 12: The 15/85 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: 400-500 g/m2. Height: 330 cm. Tested at 17% THC. Difficulty: medium.
The Aromatic Three
Leading with Limonene, then Terpinolene, and Pinene underneath.
