Hello, do you have any tips on how to store veggies through the witer? I don't have a root cellar and my basement is pretty warm - potatoes "sprout" (thats what i call it?) there and carrots get soft in few days. The non-electric tips would be the best. Could something like this work? Winters in Poland aren't that harsh. In fact during the day temperature is about 5 Celcius Degree (41F?)
