leggy cabbage and caulis

hello gardeners I planted lots of seeds caulis and cabbage about 2 week ago  indoors in a heated prop they are like 3-4 inches tall now ,will I still be able to plant them ?very leggy or start again,can you plant them a bit deeper help!!

I'll second DD - sow again somewhere cool to get sturdy little seedlings.  The odd leggy seedling can be replanted deeper, but best to re-sow if they are all drawn. 

Unless you have an unheated room with very good light (and this may still be a bit warm) or a sheltered area outside which can be protected from slugs and birds, I think it best to sow direct.
