Hi Steve,

Netro algorithm encourages longer water time and less water frequency, which will help growth of the roots. It will also break long water time to several small slots to prevent water runoff.

Some zones are watered multiple times a day, you probably selected clay, clay loam or loam as the soil type which accepts water slowly, often as little as 1/4 inch per hour and that is why we break the watering into many pieces to avoid water runoff.

Thanks,

Wency
