I bred them in my newt room without any special treatment. The room's window stays tilted open year-round. This drops winter temperatures to 12°C. Summers get warm, but the room cools down most nights. The tilted window also exposes the animals to natural air pressure shifts. Lastly, my aquarium lighting strictly follows the outside daylight hours. While Chicago has colder winters and Virginia has hotter summers than the Netherlands, you can still find ways to give your animals winter cooling, natural air pressure shifts, and decreasing daylight hours in winter.
Hope you will find at least one male. This an absolute beautiful species, with interesting behaviour and courtship display. You can raise the offspring semi-aquatic btw. With a maximum water level of 5cm filled with aquatic plants (preferably moss, like Java moss) the animals won't drown, but you can still keep on feeding aquatic food items like tubifex or black worms.
