What’s inside

40 pages of actionable irrigation strategy.

From first-principles sensor setup to advanced week-by-week steering — everything you need to run a precision irrigation program.

Section 1

Sensor Placement & Calibration

Zone sensor strategy, the 70/15/15 rule, field capacity standardization, and TDR vs. capacitance EC comparison.

Section 2

Vegetative vs. Generative Steering

How irrigation, dryback, and EC work together to shift between growth modes. Absolute vs. relative dryback explained.

Section 3

P0–P3 Phase Breakdown

Every irrigation phase explained — from P0 additional dryback through P1 ramp-up, P2 maintenance, and P3 overnight dryback.

Section 4

Copilot Configuration

Step-by-step setup for Growlink’s Copilot program — schedule, targets, suggestions, and Autopilot mode.

EC stacking strategy with field capacity lock

Section 5

Week-by-Week Strategy

Detailed steering targets for Stretch (weeks 1–3), Bulk (weeks 4–6), and Ripen (weeks 7–8) with setpoints and environmental targets.

Environmental and irrigation setpoint reference tables

Section 6

Advanced Setpoints & Targets

Environmental and irrigation target tables, runoff management, flush protocols, and failsafe configuration.
