I have done flasking once.
I used the flasking method in this Orchidboard sticky:

I also used a home-made flasking medium, recipe obtained from the blog for Dokmai Gardens, Google the phrase "how to grow orchids from seeds - kitchen style" and Dokmai, you will find it.
On another forum (Orchid Geeks), I have a long-running thread on my efforts to grow my own orchids (Cattlianthe Golden Wax) from seed. I posted there recently, it should not be hard to find the thread (my user name is different on that site). That thread tells you everything that I did, or tried, and what worked, what did not work. I have a few tiny seedlings still growing after 10 months. I am sure that well under 1% of the seeds that germinated have survived, but still consider the experiment a success, at least so far.
I will ask the moderators what the policy is on linking to other online forums and blogs. If I can, I will post links to my thread and to Dokmai.
