Hi I am purchasing a juvenile cherry head about 15 months and 4". I live in the PA in the colder northeast.Spring is coming and I have outside enclosures for my Russian tortoise and box turtles. I have never owned a tropical species and I am aware they need to be warm but was wondering what temperatures are they able to be in outside enclosures. Do I wait for the hot summers or can they come out in the spring with certain temperatures? Thanks
