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.
