Once you've pollinated your flower it will take approx 4-6 months or longer before you can harvest the seed pod. Seed pod is harvested when it begins to turn yellow for green seed or when it splits for dry seed.Then you have to flask the seeds using a sterlile media. This is the mother flask. Time in these depends on your germination rate and growth of seedlings. Generally a few months. Next you'd reflask into what are called replates, and again dependant on the growth rate, they will be in these for approx 6 months before deflasking in Compots (community pots). From here it could be anywhere from another year to several years before they become blooming size. It is a rather long process compared to ordinary houseplants.
This is all just general info with approx times and all depends on the vigor of your cross and how you grow them.
Here are some links for further reading if your serious about flasking.
