- Worth noticing
- Weather estimates cannot account for greenhouse glass, screens, whitewash, or grow lights; the site recommends crop-level light measurements for greater accuracy.
Field notes
The flow asks growers to locate the greenhouse, then choose sensor readings or weather-based estimates for light and temperature. Its RTR explanation gives a sample strategy: start at 14.3 °C, add 6.3 °C for every 10 mol/m² of light, and cap the temperature at 24 °C. The page cautions that weather data cannot account for greenhouse coverings or grow lights, and points growers toward crop-level measurements for greater accuracy.
