You’ve heard me throw around “ET” systems, smart controllers..etc for irrigation systems. What do these things really mean to you? WATER SAVINGS=WATER EFFICIENCY…that’s what. A basic ET system is something like Hunter’s Solar Sync which reads temp, humidity, etc. based on regional settings and determines the optimal amount of watering. ET stands for evapotranspiration – which means this (in IG terms) – the rate at which water evaporates from the soil, plants, etc. Think this way it just rained say this morning; all day it was overcast, and humid thus not as much water evaporated from the soil and your plants therefore meaning you need less water next time your irrigation is scheduled (if tonight for instance).ESP-SMT_md
