This way you can experiment with different supplements and determine which works best for the genera you're working with.

Agreed. But media from the OSP is really cheap, so you may as well buy a few different types if you're placing an order. If you're ordering from Phytotech than shipping is outrageous so you might as well get all you need in the same box.
My point is just that a liter's worth of media is about 5 or 6 bucks. To buy liter-packs of 2 different kinds won't cost you more than buying two of the same type and then adjust one yourself.
You could even make your own, but just starting out you're better off with a prepared media formula with known concentrations. Once you have a little experience to work with, then try making modifications and doing experiments.
. I can use their ready made medium but I'm not sure it would work for orchid seeds. They use it to grow veggie plants from meristems. Otherwise does anyone know of a good recipe (or a website with one) for a medium? I have access to a closetfull of of ingredients, so can pretty much do what I like. Now all I need is seeds...
