The red bulb might not be enough to get the proper heats for day time. My 40w red bulb keeps my enclosure at 77-78 degrees perfect for night time. I have another lamp with a 40w regular energy saving bulb on a dimmer to get the rest of my day time heat which should be 82-84 degrees. Get a digital temp/ humidity reader they are much better. I used to have the same on you have and it would cap out at 60 percent humidity. To help with humidity saran wrap 3/4 of the top.
