I agree, that's an amazing looking plant you have there. What kind of soil are you using for that guy? It looks like it changed since you started the grow log.
Thanks!

I actually haven't changed the soil, I think it could be because the soil is damp in previous pictures whereas in the latest ones the top layer is dry so the colour seems different. As I recall (I don't have the bag it came in anymore), it's a peat based potting soil, I mixed some perlite in with it. It's nothing special, just supermarket potting soil, but it's the only soil I could find that didn't have time-release fertilizers in it. I need to buy some more tomorrow, so I'll let you know what it is exactly (provided I can translate everything of course

).
