Newbie orchid grower seeking help

Since i have access to tissue culture facilities and all necessary
culturing medium (M&S etc), I thought I would dabble in orchid growing
from seed and decided to fertilize a dendrobium. 3 days after
fertilizing all the flowers, 90% of them wilted and the stigmata
started swelling. It's been 2 weeks or so since I did this and was
wondering whether the plant should be treated in any special way in
order to produce viable seeds. any necessary changes in light cycle,
fertilization? temperature etc etc?

Any help would be smashing thanks!
