Optimize, measure, automate

Your setup is running, and now you want it to be reliable, tracked, and comparable from one season to the next: accurate measurements, oxygen, light, sensors, and alerts.

30 to 250 € depending on the sensors One evening per step 6 steps

Measuring probes in a lettuce reservoir and graphs on a phone
  1. 1

    Accurate measurements first

    Two-point calibration, temperature compensation, weekly comparison: without reliable measurements, nothing else matters.

    pH and EC testers

  2. 2

    Mastering the solution

    Recipes, A and B dosing, EC drift, deficiencies: the solution is the true soil of the garden.

    Nutrients

  3. 3

    Oxygen and temperature

    At least 4 mg/L of oxygen for lettuce, a cool solution against Pythium.

    DWC and air pumps

  4. 4

    Calculated light

    Think in DLI rather than hours: PPFD × hours × 0.0036.

    Grow lights DLI calculator

  5. 5

    Sensors and alerts

    Temperature and level first, then EC and pH; ESP32, ESPHome, Home Assistant, alerts on your phone.

    Automating your garden

  6. 6

    Compare and document

    Variety trials, grow log, cost per kilo: results you can share and compare.
