So I thought this would be a great idea to do and did some quick research that everyone might enjoy. I was worried about the plastic under metal halides, but you might worry about your inhabitants before worrying about the plastic if that were the case. At worst it will expand and become a little loose. I believe the pond netting is polypropylene.

Anyway, how is this top doing for everyone? Is it worth doing myself? Is the stuff everyone is using water pond and garden netting? Thanks.
