Plants growing in winter gardens are tropical, subtropical and deserted. For tropical, excellent environment will be warm and damp, twilight — for low. Subtropic needs more light and a periodic decrease in temperature to 5-10 degrees, but desert plants need to provide maximum light and heat with a minimum of moisture. Therefore, it is recommended to divide the winter garden into «climatic zones» in order to give plants exactly what they need. By the way, many plants do not like shadow, especially for plants with light and thin leaves. Such types need additional lighting.
