What you need (full setup)
🔧 T5 HO UVB fixture (5.0 or 6%)Essential for vitamin D3 synthesis and calcium metabolism; reduces MBD risk.🔧 Basking lamp (halogen or incandescent)Provides intense heat to reach basking temperature of 95-105°F.🔧 Thermostat (for heat source)Prevents overheating; crucial for safety and consistent temperatures.🔧 Digital thermometer/hygrometerAccurately monitors ambient temperature and humidity levels.🔧 Substrate (coconut fiber, cypress mulch, or soil blend)Holds humidity well; allows burrowing and is digestible if ingested.🔧 Water dish (large, heavy, shallow)For drinking and soaking; must be stable to prevent tipping.🔧 Food dish (shallow bowl)Keeps food off substrate; easy to clean and monitor intake.🔧 Hide box (at least one each on warm and cool side)Provides security and reduces stress; essential for thermoregulation.
