Ant Plants thrive best in bright, indirect sunlight conditions. They also do great in well-lit terrariums, given the terrarium is big enough to allow your plant to grow. Be careful not to give your plant too much direct sunlight, this could cause their leaves to burn. You can also use artificial lighting if your home or space does not provide the necessary light for your plant to live indoors. Place your lights a few inches above their foliage for them to grow and thrive best. A fluorescent light will provide enough warmth and light for your plants. However, if you notice your plant is lagging, try adding a space heater for some extra warmth.
