Perfect! It rarely ever gets THAT cold here. Mine are on the porch which is probably a bit warmer in Winter and cooler in Summer. I am really getting a kick out of worm farming! I plan to bring a small amount to class (in a small clear plastic jar covered with dark construction paper that we can remove to see the worms) so the students can view how hard the worms work eating food scraps. Might be doing that when we study the lifecycle of butterflies, ladybugs, and ants. We also grow plants from seeds as well. Love Spring themes in my class! I am in my favorite element at that time of year!
Thanks for the additional information (which I couldn't find elsewhere).
