tomatoes and mold

I'm trying out some seed starting kit I got at Home Depot. The tomatoes took to it like crazy (see above) -- it's only been 6 days since i started them!! I'm going to have full-grown plants by the time it's warm enough to move them outside, at this rate.

On the other hand, the beans and nasturtiums just molded, promptly. Bad seeds? I don't get it.

I'm more or less out of dirt, though, so I've got to make a Home Depot run this afternoon to stock up for more balconying later this spring. And maybe some new bean seeds...
