I grow all my paph the same : under artificial light, medium is a mix of peat (I think you call it peat), shredded hemp (again I am not sure it's the right term), shredded sphagnum moss, styroform and vermiculite. I put some clay pebbles in the bottom to drain.
Depending on paph, I use tap water (hard) or filtered water (low in salt).
Nice shots Damas. Your leaves are more of a "green on green" then two that I have coming into bloom. I took a pic and I'll try to post to night so we can all compare.
