I had no idea that anything like this was available! I've got to try them! I'm not sure that I'd start the seeds in the "bio-dome" that they sell, but I'll probably have to get that too, just to hold the sponges. This is a really great looking product! I also like the fact that I won't have to dig such big holes in the garden to fit all of the potting soil when I'm ready to transplant.
