I was thinking about ditching the lamp as well. Should I keep the dark light (whatever it is) set up at night time? I was told that they really need this type of light for psychological reasons... Is this true?

My apartment is already pretty warm, and I have my BP away from the A/C. I actually placed the tank in my kitchen right next to my bathroom, so I've been showering (hot showers) with the door open a little which has been keeping the humidity up. (I know it's weird...)
