12"x12"x18" Kit

Transform any 12”x12”x18” enclosure into a thriving bioactive ecosystem with our complete Bioactive Vivarium Starter Kit. Designed specifically for microgeckos, small geckos, invertebrates, and other tropical species, this kit includes everything needed to establish a healthy, naturalistic foundation for your enclosure.

Each kit contains a LECA drainage layer to create a false bottom beneath the substrate, a precision-cut substrate barrier to prevent mixing between layers, and 2 quarts of our nutrient-rich Girl Dirt HBG Mix. To jumpstart your enclosure’s clean-up crew, we’ve also included a thriving culture of springtails and your choice of isopod species.

Our Girl Dirt HBG Mix is formulated to support beneficial microorganisms, plant growth, humidity retention, and long-term bioactive performance. Combined with springtails and isopods, this system helps break down waste, recycle nutrients, and maintain a healthier environment for your animals.

Perfect for small enclosures, tropical terrariums, and bioactive reptile or invertebrate habitats, this all-in-one kit takes the guesswork out of creating a beautiful, functional ecosystem while providing a strong foundation for both plants and animals to thrive. Whether you’re setting up your first bioactive enclosure or building a display-quality miniature rainforest, this kit provides everything needed to get started.
