Hi everyone,

I have a glass tank set up it's 36x18x18. I have the top screen covered with aluminum foil and duct tape over that with a square cut out for a light (for day/night cycle). I can keep my temps fairly constant, 90-93 on warm side and 78-81 on cool side. My problem is my humidity. I finally got it up into the 50's and 60's but during the day it will drop down to the 30's sometimes. Is this normal and will it affect my BP? My tank is in my den on an outer wall of the house. It's a room that is open to the kitchen and all the way up to the second floor ceiling so controlling ambient temp in the room to affect the tank is virtually impossible. I thought perhaps my light is drying out the tank so I kept it turned off. It raised the humidity some but it still is lower than at night which can get up in the mid 60's. Oh, and I put a small bowl of water over the warm side to raise the humidity but it still dips in the daytime. Thanks for all your help!
