Snowy Falcon seemed to be successful with the pure LFS. I like to mix sand and peat and have a layer of LFS on top, along with pine needles (courtesy of Maehem). Most people use Perlite and orchid bark in their mixes.
Actually I root my cuttings in their final home. Takes alittle while for them to start sprouting, but once they start to grow, they don't hafta be disturbed to be transplanted.
They do seem to grow bigger quicker once they do start.
Mix I use these days: peat/perlite, lava rocks, some charcoal, little orchid bark, very little lfs.
I've noticed plants seem to take off quicker, then slow down after awhile in pure lfs. While plants in mixes tend to steadily grow stronger and faster with time.
Nothing scientific, that's just the way it seems to me so I could be wrong...
as far as my personal experiance......pure LFS works fine up to about a 6 inch pot......bigger than a 6 inch and you need orchid bark or something to keep it from getting compacted. seeds i prefer starting on ground coconut husks so i dont have to wory about moss overgrowing them..........with the exception of the extreamly slow growers you shouldnt have to worry about the moss over taking the seedlings.........
