    Around here, if you water that early, your setting yourself up to possibly get a fungus in your lawn. Like going to bed with wet pajama's. I like to start them about 5 in the morning where the zones are just getting done when the sun is starting to dry the grass blades off. Hopefully this keeps the fungus from starting. Golf courses water all night long, but the have a funguscide program to stop it. A lot of people think they save water by watering just before dark, not as much evaporation. You might be able to water at night and get away with it, but if you get the fungus, its a PITA to get rid of.:hammerhead:

    Tim, the length of time a zone runs has to be determined by what type of heads, what are they watering, the type of soil you have and many other factors. A simple first step is to water less often and deeply to get at least an inch of water per week to most plants needing irrigation, including turf. You can check the amount of water the sprinklers are putting out over a specific time period with rain gages or simple cups or cans with measured markings.

    Here in NJ where the heat and humidity can play havoc, especially encouraging fungus, you have received excellent advice on the timing for to start your watering schedule. Typically you want the sprinklers to be finished when you awake and will need the shower or other water devices inside the home. If you have too many zones to finish, you may need to start earlier or split the application up over a couple or several days. You don't want to try and get the 1" or more in one soaking, as more than likely you will create runoff which is ineffective and wasteful.
