The Lucky Reptile Hydro Fleece 100x50cm is a versatile substrate layer designed to enhance the moisture management within terrariums, promoting a healthy and humid environment for reptiles and amphibians. Measuring 100 by 50 centimeters, this fleece can be easily cut to fit any terrarium size, making it an ideal base for layering substrates or as a standalone moisture-retaining layer. Its ability to evenly distribute and retain water aids in preventing the substrate from drying out too quickly, ensuring that the habitat remains conducive to the well-being and natural behavior of the enclosure's inhabitants.
