Spider plants prefer a comfortable room temperature, roughly 13 to 27 degrees Celsius, and dislike cold shocks. Keep the plant away from drafty windows, open doors and cold balconies at night. At the same time, do not place it right next to a heater, fireplace or air conditioner, since hot, dry air can scorch the leaf tips. A steady, moderate spot is best. If you keep plants on a balcony, bring them indoors on cold nights.
