I received this kit over a month ago. I followed the directions pretty closely, although I wouldn't call myself a green thumb. Everything sprouted but about half of the seedlings didn't make it in the long run. Certain plants seem more hardy: cilantro, mint, oregano, chives and basil all have since been transplanted and are doing well. This is a great, easy way to start herbs from seed and the tray is reusable. It also comes with more of the starter "pods" than will actually fit in the tray, so you can always try a second batch later after you have transplanted the first batch to larger containers.
