Irrigation and fertigation controllers for commercial greenhouses
A commercial irrigation controller schedules valves and pumps; a fertigation controller also doses nutrients and holds EC and pH targets. Size it by the number of valves and sectors, dosing channels, water sources and the sensors that should trigger irrigation, not by greenhouse area alone. Garden timers are a different product and are not covered here.
