I have some questions on humidity. I have not been on the site for a while. I used to have a giant day gecko. Now I have not had anything in the tank for about a year. I had my gecko die on me last year. Not sure what happened. I tore the tank apart and cleaned it out and re did the whole thing. I have always battled humidity. I have added a waterfall which I thought would get a more constant humidity. But as of lately it seems to drop quickly. I have all live plants except for a few vines on the back. The lower portion of the tank stays around 75. Middle of tank is around 83 and basking spots are around 95. I use an exoterra strip light that holds. 2 fluorescent strips and 2 halogen bulbs. I also have a 24 " fluorescent light in front. I have a ceramic emitter near the front hooked to a thermostat set at 75 for night heat. I have a new model monsoon 400 that actually works ( they sent me 4 over the years must have fixed their problems). The bottom of tank has hydro balls and I have a couple inches of Eco earth as substrate. I have sealed up most of the top of tank with plexiglass and have aquarium tubing on the door areas to seal them up. Have most of the vents across the bottom taped off. My question is how the heck do I still have humidity issues being low. If I mist the tank it goes up to 70 to 80 percent then drops quickly to 42 where it is now as I write this. One day in the future I want to put a gold dust in there but I'm experimenting with the humidity now so I can get it right for the gold dust when I can find one. Sorry for the long winded post but I figured someone would have some ideas. All yea, tank is 36L x18 W x 24 T. Any I put would be great.
