You have 2 pumps instead of the standard 1, but that could be worked out easy (Especially if don’t you need them to work independently). There are provisions to provide pumps with power when zones are on. If I understand this correctly, your bay 1 & 2 solenoids can be operated by schedule with OpenSprinkler (they are just valves or ‘zones’). The rates can be worked out since the Venturi injectors are rated.
#OPENSPRINKLER PH MANUAL#
The reason for manual override is when using bore water, the EC sensor cannot read it and so the control of the Fertilizer control solenoids needs to be controlled manually/hard coded. The amount of fertilizer is controlled by using the solenoids which turn off and on depending on how much EC the sensor is reading.

So the system works with Venturi Injectors which have no moving parts and use physics to inject the fertilizer into the mainline. As long as I can get the point across I suppose. I’ll draw up a diagram in paint, forgive me for the roughness but I’m not very good at it. As well as 2 pumps and Solenoids at the outflow point to control which bay to water.

To work, the system need to be able to control 2 solenoid valves based on the input of an EC sensor, with a manual override. ( which can be upwards of around about $7000. I’ve been looking at trying to build a DIY system and I’m looking for something flexible that I can use to avoid paying the cost of a new system. Hi, I’ve been looking at the Open sprinkler system and I’ve been wondering if it’s possible to modify it in order to apply it to a fertigation system for a small farm.
