About The Sister Auto
Days 1 to 14, seed to fourth node: Expect The Sister to crack in roughly 48 hours on damp paper towel and to break soil by day three. Early growth comes in low and wide — broad seed leaves first, then the dark fan leaves the indica side is known for. Four nodes by the end of week two, stacked close together. Damping off is rare if you hold near 70% humidity through this stage.
Weeks 3 to 6, building the frame: Top at the fourth node and the laterals take over fast. A 60 x 60 cm footprint filled by week five is normal, still under 40 cm tall, which is what makes this workable in a small tent.
Bloom, weeks 1 to 60: The 77/23 character becomes obvious here. Linalool usually shows in week three and strengthens from there, with trichome cover visible without a loupe from about week five. Indoor yield: up to 250 g/m2. Height: 90-120 cm. Medium. Tested at 23% THC. Difficulty: medium.
The Aromatic Three
Leading with Linalool, then Myrcene, and Caryophyllene underneath.
Difficulty: medium. In flower for 50-60 days. Stands 90-120 cm. Medium. Indoors it returns up to 250 g/m2. Outdoors, up to 300 g/plant a plant.
