I've been fiddling with automated watering systems. Building them from scratch and controlling them via the inter-webs. My biggest problem is getting even water flow to each pot. The plants closest to the pump get too much water, those far away get too little. Are there any tricks I can incorporate into my design to smooth the water flow automatically. Right now I have to poke/plug holes and constantly tweak the system.
I feel I may be missing some major design principle of such systems? Any hints? Or things I should study to find a method on my own.
