  • Good value
Style: Germination Mix Unit Count: 768.0
I was surprised that it came in a lined box, but now that I've gotten used to the packaging I wish more material was shipped this way. Very easy to store! The mix itself is nice and light and a very fine grain. No lumps at all! More than enough in the package for our spring starts.
