What kind of lighting conditions does my terrarium need?
Different plants need different qualities of light. Desert terrariums need least 5-6 hours of direct sunlight, like their natural desert environment. These terrariums do well in an unobstructed south or west-facing window. Woodland terrariums like indirect filtered bright light, much like their natural environment under the forest canopy. Make sure that the terrarium is placed in a bright spot out of the rays of the sun. An eastern or northern exposure is great. Woodland terrariums need natural light, so a shadowy position in your home will not serve your terrarium.
