i would go out and buy a low but wide profile rubbermaid container,use this as your rez and just sit the tray on top of it,drill too holes one for your feed and one for your return. do a half inch feed line and a 3/4 return.if u want cheap trays go to home depot and look into mortar mix trays.i use them for vegging cuttings.i have the moms in 2x2 botanicare tray set up the same way but its a top feed drip and the water just drains back into the rez it sits on.
