Wicking tray to bottom water plants

[Farside]

I am looking for some large plastic/poly trays say 1200x450 x50  or thereabouts to make some wicking beds so can bottom water plants. The trays are filled with course sand/gravel and topped with tank water. I have looked at a number of hydroponic trays, automotive drip trays and spill trays but none really what I am after at the right price. Currently using an large saucers, old kids shell wading pool and wheelbarrow but it is not especially aesthetic if you know what I mean. Currently thinking about using some pondliner framed with some 70x35 timbers but seems like overkill.  Ideas welcome.

Have you tried storage tubs @Farside?

I am using tub of garden cart and pool however these are higher than I would like, i.e. often 15-25 cm rather than the shallower 5-8 cm.

Looks like the trays used in the video.

these look like exactly what Santa wants to put under the Christmas tree, ok it's a fig tree but that is our secret. Many thanks Brad
