Rooman, the room temperatures are OK but I hope you have a basking light and a UV light for him. Without proper UV, they get MBD and a regular 40 watt incandescent bulb typically provides a basking site between 80 and 85 degrees for proper digestion of food.
Humidity and misting are very important for the health of your Jackson's but the cage furnishings need to dry between mistings to prevent mold /bacteria growth. That's why it's best to make a drainage system for the cage, as you don't want puddles sitting overnight or for days.
The humidity should always be above 50% and long mistings will encourage him to drink.
The easiest way to ensure enough hydration is to use an automatic misting system like the Mistking or Aquazamp systems.
