fauna/flora is the first flub up I've seen you do, Calin. I've said it before and I'll say it again, that I am very impressed with you command of American English.
Wintersowing is the best way to please alpine seeds when you are not sure of what course to take. It will satisfy the germination requirements of the greatest number of kinds of seeds. For many years, it was the only way I started alpines from seed.
This pic taken in 2011, and a few pots were started indoors, though.
