I was just thinking; it seems a lot of trouble with Neps and other CPs is in regard to keeping the humidity levels nice and high, so I was just wondering if anyone does what the orchid growers do - that is, you place a nice thick layer of saw dust (or choir, I suppose) around your pots and staging and keep it wet... it stays wet a rather long time and thus defuses humidity slowly. It might not be the most attractive thing in the world, but it would sure help, wouldn't it?
