Same weather. Less water pumped.
Simulation on the weather from 2015 to today: watering every 7 days, or with Sakia.*
Where is your field?
What do you grow?
Method: every season since 2015 was simulated on the weather that really happened (ERA5 archive, Open-Meteo), as if Sakia had known it in advance. A reasonable hypothesis: each day's decision only needs that day's weather, the most reliable part of a forecast.
