I always read that it was better to water early in the morning than in the evening. I see Netro gives the option of 2 frames daily though.  I turned on two frames and created a lengthy frame in the morning and evening for watering. Now when Netro schedules my watering it breaks it up between the two zones - even though the morning zone is long enough to hold the entire watering schedule for any partucular day - so presumably Netro thinks it's better to do half the watering in the morning and half in the evening.  My question is "What is the best practice with Netro watering, and why does it choose to water morning and evening rather than just morning? ". I was sort of expecting it would only use the second frame if the first frame wasn't long enough - but this is not the case.
