Hi Reinbo15,
I learn orchid propagation by searching information on the internet. Some links may help:
HORT 400 ORCHID LAB
Lotte & Thomas Orchids
Sowing
There are a lot of good propagation information in this forum too. The keyword of orchid propagation in vitro is contamination. Search for the orchid/tissue culture sterilization. Learn and practice how you sterilize your seeds and equipments. If you can avoid the contamination then sowing orchid in vitro is quite simple: sterilizing seeds , equipments and media, transferring seeds into media, providing light for seeds to grow up.
