Pie Pan Trays

I just thought of this yesterday but I have a couple of plants sitting in pie pans for trays and I remembered reading in the nep forum that metal baskets would kill them (something about zinc I think). The sarrs seem to be doing ok, new pitchers coming up, but if there's any chance for ill effects then I'll replace the pie pans. Aww screw it - I'll just replace them. Guess I answered my own question.

If you have the cheap, flimsy ones, they are probably just aluminum. Whether or not aluminum would leach out I don't know. I wouldn't think so, but I'm no expert.
If I recall correctly from my days as a chemistry tutor, when aluminum oxidises (small highly charged metal ion) it result in a slightly acidic solution. If that is the case then they should be fine. I'll check up on it when I get home.
Last year I had some plants in metal trays. The pan began to rust, and the soil seemed to be showing mineral build up. I wouldn't advise using them.
Well, as luck would have it, they are indeed the cheap flimsy ones and I'm fairly certain they are aluminum. I will, however, replace them with plastic. Ever heard this one... "better to be safe than sorry"? Yeah baby, yeah.
