Crop Steering is the science of actively manipulating environmental triggers (Temperature DIF, VPD, Substrate Water Content, EC) to guide plant morphogenesis toward either vegetative growth (biomass, leaves, thick stems) or generative growth (flower initiation, pollen fertility, fruit ripening).
1. The 3 Primary Steering Levers
- Temperature DIF ($T_{day} - T_{night}$): Positive DIF ($+3\text{ to } +6^\circ\text{C}$) drives gibberellin synthesis and generative fruit elongation, while negative DIF suppresses stretch.
- VPD Differential: High daytime VPD ($1.2–1.5\text{ kPa}$) increases transpiration tension, promoting strong flower trusses.
- Substrate Dry-Down (%): Deep overnight dry-downs ($8–12\%$) generate mild osmotic root pressure, signaling reproductive focus.
