Dwarf french beans,how should they look?

6" tall in 11 days and to first set of leaves is rather too leggy in my view.

They may be OK but it sounds like insufficient light.

You could try putting foil behind them, to reflect more light back onto them.

Thanks a lot,I think I'll put them in my upright cold frame.
Do you think that will be ok,failing that it's not too late to plant some from seed in the allotment is it?

My dwarf french bean seeds are still in the packet am I too late to grow in pots under cloche then plant out on allotment.

No; see my reply just above your post 

The plants I risked planting out under cloches (I shall be sowing more soon) have survived but have not put on much growth.

The new ones will no doubt catch them up.

It is an experiment that I may not bother repeating (and it has not even been that cold at night at about 5/6C ...although they do prefer a nightime temp of at least 10 C)

As I said, new ones will soon catch them up 

To all many thanks for advice.
Prior to retirement I did everything late now I am too early in many cases.

Salmo, I am just up the road from you at Crowland.
