As i promised
All they are composed of, 12v pump, 12v cycle timer, 12v power supply “i just have one that runs all of them plus my fans”, a 4 port drip irrigation head, 1/2" irrigation standoff riser, 1/8" drip tubing for nozzles
, and a 1/2" pvc cap with a hole drilled in it, and a little 1/4or 3/8" tubing to act as a pickup for the pump, just allows the pump to suck more off the bottom. Cost was about $20cnd per reservoir for me.
