Where it all started - Generation 2
Generation 2 - May 2015
This was our first attempt at 'Ebb & Flow' automated watering using a length of PVC fence post with end caps and center section removed to form a tray. Water was pumped in at one end and returned back to the reservoir at the other. The grow mat was supported on plastic pond filter material. The system worked but roots were difficult to remove from the filter medium.
