Fungus on spaghnum moss Jewel orchid?

[monivik]

Ok, so I got this little Macodes Petola exactly 3 weeks ago. Originally I was asking why the top of the spaghnum moss was green, and I was wondering whether I should repot it. However someone adviced me not to do it so as to not shock the plant as it first has to adjust to it's new environment. I was also told the green color wasn't a particularly bad thing.

Ok, so three weeks in... I've been noticing something white on the top layer of the spaghnum moss, it was a little bit to start with but it seems to be a lot more now. First of all I'm wondering, what is it? Is it mould, fungus? Or is it just calcium from the water, I've just been giving it tap water like I do with all my other orchids. Our water is soft water, so I understand that's not too bad.


So if it is fungus... I'm not too happy with this. Does this mean I should repot?


Another thing, this is the first Jewel orchid ever for me, and the first orchid that I'm told should never be allowed to go completely dry. That second part is where I think the hardest part lies in... finding the balance and learning when to water. I'm sticking my little finger in there to check how moist it is, and I'm also trying with a tooth pick (it's really a too small plant/pot for a skewer).

In general so far the orchid looks good. It's opened up two new leaves on each side and I can definitely see it's grown a little since I got it. But yeah, how to find the right balance in watering, I guess that's the tricky thing. I suppose it also doesn't need that frequent watering as it's not so warm anymore, summer is over fall has started.
