looking for drip/dwc

ok. my last grow i used a producer from bc northern lights. I am guessing that we can classify it as a drip/dwc system (due to the roots being imersed in the resivor and due to the drip on top.

I would like to make my own version of this system but having trouble finding the trays and lids. the size I was looking for would be 2' x 3' or 2' * 4'. really looking for a 2x3 so that i can cut 6 to 8 holes in the lid and run the cups that way. anyone know of a store that would have those kind of trays. The height for the producer resivor was 6 or 7 inches. anyone have any ideas?

Right now Im running a 5gallon bucket bubbler with top drip feed. Thats all you need. One 5 gallon per for big plants but next time when I go to flower Im changing to 10 gallon and adding a water recirculater with filiter. This will produce monsters. Maybee this will help. Confined spaces cause problems.
