Have redone the watering system in the seedling area this week. I replaced the large pulsating sprinklers with shrub sprinklers. This has reduced the watering time from 60 minutes to 20 minutes because the water is more concentrated.
Both of these sprinklers put out 3 gallons per minute, the small one is the new one.
I spaced these at 10' between each one and each row of sprinklers covers two beds.
