On Jakes's advice I have sown some hardy annuals outdoors under glass.

They are now a couple of inches high in their seed trays and I'm

wondering when to pot them up. They will obviously slow up when the

weather gets colder but I want to give the roots all the room they need.

What I have are nigella, cornflowers, californian poppies, and night

scented stock. They can probably just about be handled but maybe I

should leave them for a bit?

Any advice appreciated

Just a quick one to add to my post further down.
Hardy Annuals and other hardy plants are what it says on the label, they do not need mollycoddling and there is no need to use precious covered space for them, in fact for autumn sowing they need to be started hard and kept hard, I'm rather afraid you'll find it difficult now to acclimatise those plants to the great outdoors.
An aside to the question, I've used hardy annuals with some success in part of a border that is full of snowdrops. As the snowdrops were dying down a couple of years ago I scratched round with a rake and emptied a few packets of hardy annuals in there, another scratch round and then left them to it. That year we had a lovely annual border after the snowdrops and I then left them until just before the snowdrops started to show through so they self seeded in autumn and spring. We had a good free show this last summer as well.
