Dear customer,

We noticed the watering time for Zone 5 is longer than other zones, but the frequency of Zone 5 watering is not very high. Sometimes it takes 3-4 days to water once. 

In addition, the zone area of Zone 5 you set is relatively large, so the amount of watering required will be more. Netro AI will calculate the watering amount according to the area and plant type. If the ECO is still too much, the new version of the APP has added a Boost factor, and you can adjust the watering using this new feature when it is released.

Thanks,

Wency
