Just spread them on top of a pot of media (I use sphagnum moss) and keep them moist and covered (but not air-tight) until they're about 3/4 - 1" tall.

Vrieseas are slow from seeds. Expect it to take several years before you see a bloom, and since Favorite is a hybrid, the seedlings won't be true to the parent. You might get something nice, though.

Thanks, Lisa.
