What exactly is meant by hardening off? I've germinated a few seeds and now I'm thinking about acclimatising them to the outdoors. They have grown up in an unheated room which is quite cold. The seedlings are cosmos, echinacea, gaillardia and coreopsis. Oh and poppies. I have one of those mini greenhouse things - basically a load of shelves with a plastic/bubble wrap sleeve that zips up the front - is it safe to put my babies outside now as long as I remember to zip up the cover and bring them in if there's going to be a frost?
