I'm becoming relatively fond of this method because I'm starting an indoor garden that I will move to my patio when it gets nice out. Because of the limited space I will have available I don't want to start 10-20 of each seed and then have them all germinate, also only planting 5-10 could result in no germination.....planting things like rosemary that by my research has a 5% germination rate, it seems like a good idea to visually see which seeds are germinating before I plant them. But ya, if I were to plant a full garden or doing entire flats of each type, I would prolly directly sow because you are creating the ideal situations for the plants!
So much good feedback on this topic I thank everyone that has posted...the past 30 days has been like taking a crash course in herb-onomics! So much fun!
