Drainage Layers, Humidity & Clean-Up Crews
Sitting water turns substrate stagnant and causes root rot. A 2-inch hydroton layer separated by mesh creates a water reservoir.
Atlanta Botanical Garden mix (tree fern, peat, charcoal, sphagnum, orchid bark) stays aerated for a decade without rotting.
Colonies of dwarf white isopods and springtails eat decaying waste, mold, and uneaten insect carcasses automatically.
Stagnant humidity breeds bacterial rot. Modern vivariums pair automated fine misting with subtle passive screen ventilation.
Live bromeliads, pothos, and Philodendron plants clean water nitrates and provide secure natural sleeping perches.
