I started them in February under lights. I used a soilless mix with some added grit. put a thin layer of grit on the surface and sowed the seed on the grit. I had them on a heat mat but I don't think it's necessary. The seed is tiny just like Semp. seed. I use a 3 1/2 inch pot with a baggie over it. They take a month give or take to germinate.
Here's a close up.
