Here's whats posted on the sticky topic at the top of this message board regarding seed production:
On the other hand if you do want seed, than you should have at least two flowers, that begin blooming at least two days apart. Get the second blooming plant, rub it's flower against against the first one's interior, and repeat for a couple of days to ensure good seed set. Once the plant is pollinated, you should make every attempt to keep these plants in optimal conditions so you can avoid unneccesary stress and complications. Optimal (at least for my plants) is 70*-80*F and around 65% Relative Humidity. The seed will ripen in about six weeks. At this time, you should crack open the now dried seed pod, and you should see several black shiny seeds. These can be sown immidiately on 50% peat/50% sand, or refridgerated for later use. They will germinate in about two weeks in humid and bright situations. Transplant after about a year of growth.
Anyone who wants to pursue seed, BEST WISHES!!
