The Zoo Med Paludarium UVB & Plant Growth Lighting Kit is well suited for enclosures housing reptiles, amphibian and various types of plants. The UVB lights allow reptiles to better synthesize vitamin D3, which increases the absorption of calcium and helps to build and maintain strong bones as well as enhancing the natural coloration. The presence of UVA lights offer essential behaviour regulation regarding feeding, sleeping and breeding. Powerful LED lights ensure that light penetrates all the way to the bottom of your water feature, encouraging terrestrial and aquatic plants to not just survive, but thrive.
