I don't know if the bulb would make a difference in the going to bed early- is he pooping ok? I would lay off the asparagus- there is a nutrition website on the feeding board visit that ignore the kale thing it's a good staple feeder--- you need to get him some worms to lure him to the salad bowl- you will need a glass or ceramic bowl- order some BSFL or also known as nutri grubs calci worms and Phoenix worms- you can switch him over to dubias-- better nutrition and they last longer- you can keep them in a 10 gallon aquarium and feed them dubia food carrots for
hydration- and squash- you can order from here
http://www.dubiaroaches.com order large BSFL do not dust them and feed as many as you want they are a good staple feeder--- you can also order butterworms Horn worms they are a good
hydrating worm.they grow fast so order small amounts- he might be able to eat medium super worms - another good worm is silk and they too are another staple you can get them from here
http://www.reptilianarts.com if you order in bulk like 50 they come small make sure you get food too you will need to feed them and clean containers out daily-

Use 1-3 worms - make sure you add them to salad bowl in front of him the movement will entice him to the bowl
