This is the new cost reduced version of the system.  It has lower cost sprayers that actually have a better spray pattern, a lower cost valve, and a different flow setup.  If anyone wants to hear more about it, leave a comment and I'll fill in the details.

Take a look at .  You need to use a 200  mesh screen filter before the pump or the sprayers will clog.  However, these nozzles are twist lock, so you can take them off and run water through them backwards to unplug them.  The valve that I am using is a custom 3D printed valve that I designed.  Before that I was using custom designed motorized pinch valve.  Commercial pinch valves are available.  They will not clog like most off the shelf 12V controlled valves will.  I will not be releasing the new valve design because I am considering patenting it.

hey, I'm interested in trying this to grow tea bushes in my basement, any update on what the cheapest sprayers and valves ended up being?
