alright thanks guys but now im really wondering if i build a table out of wood cuz im a carpenter and i make the walls six inchs high cover the thing in panda film would that work
The only plastic tray i can find near 4'x4' are the Garland 1m trays, but they are just under 40" and a bit too small, so now I'm planning on doing the same (wooden trays).
Yes, i'd say panda film would work for a few months, i was thinking of pond linning, but i guess tiny holes will soon appear in it and i'd say the same would happen to the panda film.
I was looking around my shed for something suitable to hold water in the trays, and came across a couple of rolls of 450mm damp course. It's very tough, i might hot glue strips of that together, and see if that will work. I was also thinking of making my own fibre glass trays, but i'd say it would be toxic for the plants.
