I'm about to build my first aquaponic-system to have in my apartment. Considering building it out of barrel's or those qubicmeter chemical tanks if I can find any...

But my friend works in a factory that make sailboats out of fiberglass, he said it wouldn't be a problem if I built my tank and growbed in, for example, plywood and brought it to him so he could spray them with fiberglass.
Would be perfect so I could custom fit the size for my two living room windows.

But is there any health risk involved using fiberglass to grow food in? There's two kind of fiberglass, one is made with polyetylene and the other with something else, forgot witch one my friend is using...

P.s Please excuse the bad english.
