Big Broad Bean Plants

Hi,  I planted 'The Sutton' a few weeks ago into plastic coffee cups and I have had about 95% germination.

The plants are in my unheated greenhouse but are now about the size I would be expecting to plant out next March.  Can you please advise me what to do with them, should I leave them where they are in the expectation that the weather will change and they will slow up growth, or should I plant them in the lotty.  They are about 4" tall, quite bushy with glossy green leaves and thick white roots.  I would not be able to cover them all with clouches and as my site is very exposed to the winds it is not practiable to cover them with fleece.

Thanks BabbyAnn,

I think you are right, I do have a cold frame doing nothing at the moment so I may move them to the lotty and cover them with it.
