when should you take a pod off ready to flask, with photos

[orchiddream]

can anyone tell me when is the best time to take the pod off the orchid. I don't know whether I took mine off too early, (i took off after 6 months) as ive flasked the seeds and its been 4 weeks and cant see anything that's happened.. a few little pieces have gone a brown colour but I think that maybe the orchid peel where I scraped the seeds, but then Im not sure. it is really dis heartening that its took all this time from pollination to have a feeling its not going to work . a few photos below. please anyone reply with there knowledge.. thanks
