I do not understand how many millimeters to set. I have microsprinklers of 4lt/h and 2lt/h. I thought to set to 4000ml/h but the max is 100ml/h.
How to calculate? I have a big terrace with 30 plants and various microsprinklers.
If you are not sure about the exact flow rate, you can select "default" and see if it meet your watering needs. If not, you can adjust the value.
I think you have units confusion.
mm/h is not ml/h
mm is used in irrigation and meteo raining and is the amount of water rains in a square meter. so:
1 mm = 1 liter/m2
1 mm/h = 1l/m2/h
in your case because you have to divide your 4lt/h by the m2 of irrigation area in order to get the lt/m2/h
hope it helps
