Welcome! carrots have a germination time of about 15-20 days and need reasonable temperatures, around a consistent 8 degrees- how long are they down?
When I say overwinter I mean plants can be left and used from the garden straight thro the winter into next spring.
You could try Homebase for broccoli or caulies seedlings. I saw some there last week going cheap. I would risk a packet of seeds and grow indoors if you can't get the seedlings. Likely you'll get away with it as seedlings are usually only a week or so old. Alternatively if your in Dublin check out Midleton's on Mary Street.
