Winter Density

Have planted 3 different Winter lettuces a few weeks ago. Valdor, Norwegian Brown and Winter Density. The best by far, in both greenhouse and outdoors is Winter Density. Lovely darker green cos type leaves, very healthy and streets above the other two. Photo to follow.

I'm still thinking about my hungry gap! So I am going to plant some pak choi in the propagator in the greenhouse to give it a good heads start, then plant seedlings out into a growbag in the greenhouse. Does anyone have any suggestions for hardy Winter edibles?
