I used ChatGPT to help me understand the advanced irrigation settings, which were new to me. I described the environmental characteristics of my lawn, including sun exposure, two types of grass, and the contrast between areas with newer grass in full sun versus shaded zones with no runoff. Using default settings didn’t seem appropriate given these differences. Once I had outlined all the relevant details, I asked ChatGPT to prompt me for anything I might have missed. It then helped me fine-tune the configuration. For example:
| Setting | Recommended | Why |
|---|---|---|
| Available Water | 0.17 in/in | Clay loam stores a bit more water than sandy soil. |
| Root Depth | 6 in | Good average for Zoysia in partial sun. |
| Allowed Depletion | 35 % | Keeps the soil from drying out under tree canopy. |
| Efficiency | 70 % | Typical for rotary sprays with decent coverage. |
| Crop Coefficient | 0.65 | Less transpiration in partial sun. |
| Nozzle Rate | 0.8–1.0 in/hr | 1.5 is too high unless you truly have high-flow fixed sprays. Do a cup test if unsure. |
