See the ice in the top right corner of the container?
I have been sprouting wheat in large flat trays to give to the hens and I keep it on the bench in the laundry. The laundry is outside and is usually fairly warm, due to the insulation in the roof/walls, in Winter. I was stunned to discover this, especially as it was 10am, when I found it!
Strangely enough it was a lovely warm day and I could garden in just a t-shirt and jeans.
