Down to Earth

So winter is around the corner and I planted the last of what I am told can survive in greenhouse environment. Siberian Kale Blue Russian Kale and Collard Green. This photo is from before I put the green house over .
I grew them all from seeds but with the cool autumn it took one more month to get them even to this small stage of 2" only. In good weather I grow 120m2 of veggies but this year was the worst in five years. Spring only in Summer , summer cool..ish 4 weeks only, ugly autumn for how long?
Wish me luck.
