Dear customer,

Netro algorithm encourages longer water time and less water frequency, which will help growth of the roots. If you want to decrease the watering amount , you can either change to different smart zone mode (ECO), or you can set up your own programs and set up your smart zone in basic level. Please check this article for more info. https://netrohome.com/forum/posts/111 

Thanks,
