So much in a cup.
I was starting a new bonsai tree scape with nothing but the tree with Christmas Moss and dwarf hairgrass on the carpet. I figured I'd need 3 cups. I couldn't believe how much I got out of a single cup once I split it all up. If I had to guess I got about 30 decent size plantings out of a single cup of this stuff. Great deal and the plants were in great shape.
