Calabrese and Brussel Sprouts shrivelling!

[Jenegade]

My Calabrese an Brussel Sprout seedlings seem to be dying, I'm not sure why! They are an inch and a half tall, just about to get there true leaves, but there seed leaves seem to be drying out at the edges and shrivelling up! What's wrong with them?

They are sat in pots on a south facing windowsill, watered occassionally when they seem dry.

Help....

You've answered your own question with the last paragraph Jenegade!

They should be outdoors now either in a cold frame or hardening off in some way.
Too warm and dry indoors!
