Hi John,
Netro algorithm encourages longer water time and less water frequency, which will help growth of the roots. If you want to reduce the watering amount, you can 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
