I have no idea how best to set the three values of the zimmerman method. I live in Italy and usually in the summer when it is so hot 30°C – 40 °C I water my garden 15mm of water every 3 days.
Could you help me to better set the 3 values?
Temperature
water
humidity
Another question: do the three values shown on windows the weather adjustment options refer for example, to the temperature present at the time of irrigation?
