Net bags?

[Kelo]

It was when I was shopping in the supermarket I use, when picking up some kiwi fruit that was sold in those netting bags, that I thought of using the nets to grow phals in. I just wonder how long it would be before the (plastic) netting rotted or was weakened by sunlight etc.? Do any of you think that it might be possible to bag orchids this way as an alternative to clear pots? It would mean that the compost would dry out faster but then the roots would be better aerated and less susceptible to rotting. It was just a thought.
