Thank you all so much for all the info, it was more than I expected I
have to say. I have removed all pods but one since this is the second
flowering year fot this particular plant (and therefore not a monster
at all, Kenni). Being curious I bisected the other pods and saw
thousands of seeds in the making... very nice to see but I feel
somewhat murderous.

This particular fertilization was not a cross, but merely self
pollination. I gathered that messing around with crosses would
complicate things and since I am just starting I thought I should stick
to the basics and expand what I have. I noted the date of pollination
and will keep a close eye on the pod to catch it before it's too late
(after 4-5 months I gather for dendrobiums no?).

So I have one pod left and I think that that should give me more seeds
than I can handle anyhow. Thanks Aaron for the tip in the medium, I
will follow those instructions.

Many thanks again for all your inputs!
