Whew! Just done repotting according to your recommendation Delwin. Perlite as top dressing. Can't go far wrong can it? :D
Here's the pic. Terracotta pot from Ikea, thin layer of LFS as bottom, middle layer peat, perlite, vermiculite mix (1:1:1) and top off with 1/2 inch perlite. Container with some gravel and thin line of water to provide humidity.
