My temps are 98.5 to 101.5 will this be ok or do I need to do something to get the heat closer together? It is a home built. Built out of a Mini Fridge. Has a fan and a turner. What can I do to get temps closer to 99.5? Put in jars of water? I am running a 100 watt bulb the light and fan are in the bottom. Would it be better to put in 2 smaller bulbs? One in the bottom and one on the top rack?
