Leopard Gecko Heating Guide
Safe temperatures, heating methods, and gradient setup rules that prevent common gecko heating mistakes.
Build a Leopard Gecko HabitatQuick Answer
- Warm hide floor/surface target: ~90-92°F
- Use thermostat control on every heat source
- Build a warm-to-cool gradient across the enclosure
- Measure surfaces and ambient temps in multiple zones
Heat Sources: UTH vs Overhead Heating
Under tank heaters (UTH) can provide a localized warm floor zone when installed and controlled correctly. Overhead heating (halogen or deep heat projector) can create stronger daytime ambient support and more natural gradient behavior.
Either method can fail if placement, wattage, or thermostat setup is wrong. Heat source type matters less than controlled delivery and verified temperatures.
Why Belly Heat Still Matters
Leopard geckos often rest on warm surfaces to support digestion. The warm hide floor target (~90-92°F) is a practical benchmark for safe metabolic function. Even with overhead options, surface readings in the warm hide remain a critical check.
Thermostat Importance
No thermostat means no reliable safety limit. Unregulated heaters can overheat quickly, especially in smaller enclosures or seasonal room swings. Use a thermostat plus routine temperature checks to keep conditions stable and safe.
Temperature Gradient Setup
Build a clear gradient: warm hide near target heating zone and a cooler opposite side for retreat. Measure warm hide surface, warm-side ambient, and cool-side ambient so your gecko can choose preferred body temperature throughout the day.
Common Mistakes
- No thermostat on UTH or overhead heat
- Heat source placement that creates one hotspot but no usable gradient
- Using only one thermometer and missing cool-side conditions
- Not rechecking temperatures after room or season changes
