I am looking at doing 2-4 auto plants in coco coir in 3 gallon fabric pots with the autopot automatic watering system but I would want to use my own reservoir and pots for it. I would like to know if people buy the parts that go into the reservoir and the trays and use them with your own reservoir and tray and pot for it. It looks like you could buy the grommet that goes in the reservoir then put the tubing from that to the aquavalve that is in your own tray but I would like to know if any of you do that on there.
