How do pros keep their terreriums humid enough?

I water with warm water every day, have and screen top, and keep a plant light on four about 8-10 hours a day. I have small bullfrogs and a tree frog in there, and the the terrerium is a long skinny 13 inches by 49 inches. I can't ever seem to get the humidity higher than 60. It's so dry, and it dries up fast. Is there a device I need? If there is, what is the least expensive thing?



I'd prefer if there was some sort of home remedy sort of thing. Thanks.

You are losing most of your humidity because of the screen top. Replace your screen top with an acrylic or glass top depending on how hot your lamp gets and adjust the opening just enough so your plants can have incoming carbon dioxide. Your humidity should soar to the upper 80% right away so adjust the opening until it maintains at you desired humidity level.

Reply:Try lining the terrarium with long strand sphagnum that you've first thoroughly wetted -- dump hot water on the sphagnum (just off the boil) and allow it to cool before using the sphagnum. You do not want milled sphagnum for this job -- chopped would be ok,

however. Nor do you want "sphagnum peat".



Sphagnum moss has "barrel cells", big water storage cells that can contain an amazing amount of water and release it slowly. Sort of a natural sponge with antibiotic properties.

Also, have you checked the temperature? Sounds like it might be running warmer than a lot of amphibians prefer.
