I am looking at adding a raised vegetable garden to my back yard. I have an existing rainbird system in both the front and back yard. In this particular area my two long skinny beds (12' L x 3' D x 2' H) will lay directly over my existing spray heads. The current heads are half circle with about a 3" throw and are watering grass that will be removed during renovation.
Being a veggie garden I was looking into converting it to drip irrigation. That appears to be a a headache. Could I put 2' risers on the existing heads and be okay? or is there an easy way to add drip irrigation to these heads? With the hot Texas summers I am concerned with water burn. Last summer it was 98 degrees at night and my grass burned when I watered at 10 pm. The only head converters I found had 4 barbs which is way more than I need given the number of heads in the bed and bed size.
There are some oddball ways to add drip to spray or rotor zones, if you have the spare capacity, and the high-volume discrete emitters like Rainbird offers ( those don't drip so much as they dribble )
Drip is economical to install, saves water and is easy to retrofit onto an existing system
It can also be very confusing to the new user.
The terminology and flow rates are different from what we are used to.
Not to mention the hardware .
