These mini ecosystems can easily adjust to temperature changes, but you might need to provide the perfect environment for them to thrive and stay healthy. Avoiding direct sunlight and heat exposure during hot summer days is recommended, as well as ensuring they�re not exposed to freezing temperatures and snow during winter. Since most of our terrariums are little rainforest recreations, we recommend keeping them in environments with temperatures between 40/85F � 5/30C, being 65/75F � 18/24C a perfect range.
