Been building outdoor Hydro Tables.. Take a peek.

It's not mosquitos that are the problem; there are lots of other larvae-stage insects that eat roots. Sometimes you can see them when you pull up a plant. They look like little black slugs. I get them on any outdoor hydro plant if I don't use the dunks. Maybe you have different bugs than me, though, I'm far away.

The synthetic boards they make for decking and siding look very promising for hydro use. I am hoping to use siding trim boards for my next flood table.
