It may be that the seeds were only started indoors a few weeks ago. In that case it wouldn't be unreasonable for them to be still indoors, which is why I asked how long since seed germination. Christy did post about seed/ling problems in another thread earlier in spring, though, but the medium looks different so I'm wondering if this is a new batch. If they are recently sown then perhaps next time they're started during the growing season it would indeed be better to sow them outdoors (in the ground) to start with.
