Hi Courtney,
I realize I'm late at getting to this thread, but I thought I'd let you know that most vandaceous hybridizers wait for their seed pods to mature for 6 months before picking them to flask. Here is a general rule:
Vanda, Ascocentrum and Ascocenda 5 to 7 months
Rhynchostylis, Renanthera, Arachnis 5 to 8 months
Many times a Vanda pod will turn slightly yellow within a few months, but this is normal and the pod still needs to mature for 6 months before picking. If the pod turns yellow and brown, or just brown within the first 4 months or so, it is usually because there is not enough viable embryonic tissue growing inside. At this stage the pod will probably split and fall off the plant.
It can be frustrating sometimes
(I've lost many more pods than have matured), but if you're really interested in hybridizing Vandas, just keep trying. Eventually you'll have a keeper, and then the excitement really mounts.
