...to my irrigation system. My current system is comprised of a Hunter SRC controler along with mostly I-20 heads (changing all from RB 5000's), 8 zones and 32 heads. Now, I would like to make this system more conservative. I find that sometimes I irrigate to much and sometimes not enough depending on weather. Parts of my yard retains a bunch of moisture, I have been working for a while to adjust the operating times on each zone. This, along with replacing the broken RB heads, has really helped. Now I would like to add something that would sense moisture in order to make the system a bit more water conservative. The bills in the middle of summer really get high. Is this possible to add to my current system and is it something that me, a homeowner, could install? I don't mind putting some time into it and was thinking of something along the lines of a Baseline S100. Would this help me or do you recommend something else?
