add perlite too if you have it.
I use LFS with 1/4-1/2 inch orchiata bark and #3 sponge rock (large perlite) from Kelly's Korner orchid supplies in my nep mix. I had a ventrata limp along for over a year in 100% sphag but with this mix it's pitchering like there's no tomorrow. I also mix in small pumice chunks in some of the smaller pots. It doesn't seem to particularly help or hurt them though
I mix my normal nep mix with a ratio of 2:1:1 LFS-orchiata-sponge rock and add extra LFS is the mix looks too "dry"
