Lee, By "long-fiber peat," do you mean undecomposed sphagnum moss or some sort of decomposed peat that retains long fibers? All the the peat that I have ever seen was thoroughly decomposed into small brown particles. Sphagnum moss, on the other hand, does come in long-fiber forms and is very useful for growing seedling epiphytes. I planted some of the Paminanthe seed that was recently offered on the PBX in sphagnum. Currently waiting to see if they will germinate. Regards, Nick
