→Keep VPD during flowering at 1.2–1.6 kPa – any outlier over several hours opens a mold window and costs yield.
→Always stabilize VPD first, then adjust EC — never change both parameters at the same time.
→Track daily pot weight, climate, and runoff EC – after 3 runs you'll recognize patterns that otherwise stay invisible.
→Calibrate pH sensors weekly and EC sensors every 2 weeks – a sensor that measures incorrectly costs more than a replacement device.
