Okay so I bought a 40 gallon breeder for buddah. The light that I had in her 20L was not putting out enough heat fot the 40 gallon. I went to the store and bought a 90 watt halogen flood light. Its been above her baking spot (about 13 inches above) for 20 minutes and its already up to 107.3 and still rising. Shes about 4 months old and 9 inches. What the highest basking temp she should have?
