Well, we do have Intratuin in Belgium. However, since Cameleon is a company in NL you won't find their products here (you will find the plants but not the fertilizer/mixes)
I'm quite happy with the "DCM Orchid" mix. (
Dutch or
translated to English, there's a video too in Dutch on how to repot Phals
)
DCM has a very good and light mix. It contains bark in different sizes (most of it is small) and very small pieces of spaghnum. You can see it being used in the video.
I've had the Substral mix before that ... I don't know what's in it but believe me, it's not worth it's money. It clearly contains bark but it looks more like a mix you would use in the garden, really bad.
I will do a check up on the roots later today. Will probably make some pics too.
