Encyclia phoenicia pod harvesting time

[Maru777]

Hello everyone! I am trying for the first time to propagate an orchid via seeds. I cross pollinated an enc phoenicia with itself - the last 2 flowers on a flower spike. I did not actually expect to get a seed pod but I now have 2. They look nice and fat right now but I do not know when they are supposed to be ripe. I’ve been reading on the method of propagation and would like to try the green pod method so I can sterilize the pod whole rather than the seeds, which seems more of a pain. For this I need to harvest the pod when it is sufficiently mature but before it opens. The problem is I have no idea when that is. I pollinated the flowers on July 8, that much I know. I have my agar agar jars ready but no clue when to cut the pods. Help please! Thank you!
