A few more tidbits and im done.
emitters come in 1/2, 1, 2.5, 4 and 6 gallons per hour delivery rate. Since we’re watering things with different water requirements if we want to keep everything simple we just use the appropriate dripper and determine that by dividing 60 min by the dripper rating then multiply that by the length of time the system will be on To determine how much water each plant is getting.
Around here cucumbers use 6Gph emitters, tomatoes and celery 2.5 and beans get 1Gph emitters and my timers in the garden and greenhouse are set for an 8 minute run time twice a day.
my fruit trees have 1Gph emitters and run for 1 hour each day.
There are lots of various systems out there, this tutorial details the simplest and therefore cheapest components. There are systems using couplings at every joint in the lines, larger and smaller hose sizes, timers in endless variety, filters, fertigation applicators, pressure reducers etc. etc. There are static systems and ones using pressure compensated emitters as well.
Netafim even makes a commercial robot that will travel thru your field and lay out the lines and spool them up at the seasons end completely unatended!
If this is something of interest to you, do a little reading to gain some basic understanding of the options and give it a try.
