Appropriate night temps

Asked April 23, 2017, 11:41 PM EDT

Can I move cauliflower and Brussels sprouts seedling to an unheated greenhouse when the temperatures at night are still in the 30s? What is an appropriate temperature to move tomatoes to the same greenhouse? Thank you!

The cauliflower and Brussels sprouts should be fine. However, tomatoes should not be below 60 degrees...especially if flowers have already emerged. Conversely, tomatoes should not exceed 85 degrees. Too low and too high temps for tomatoes in Alaska are the leading cause of crop failure in Alaska.
