Is it ok to a unheated propergator out side?

[Naga]

I wanna start off some of my flowers but as space is limited inside I thought I could make use of my new propagator and put it outside, do you think they will germinate ok or do you think it's still to cold? According to a 5 day forecast for my area the coldest night will be -2.

The ones I am planting are:

Morning Glory
Clematis
Geranium
Sweet Pea

Oh and also tomatoes would like to move out.

Still too cold for Morning Glory (it is tender: you will see HHA on your seed packet) - if you really have no room indoors, just sow it later on when it's warmer. It will catch up.

I've sowed Stock, Antirrhinum, Clarkia, Cornflower, Morning Glory, Nasturtium, Lobellia and Marigolds so far. I leave them inside until the first sign they are germinating then put them out in a plastic greenhouse. They've been out at least two weeks, all doing fine. Maybe we're a bit warmer though.

I've got quite a few seeds so I could try, I can also sow a few more I suppose!
