The Tropic Aire Humidifier isn't creating enough humidity for me to grow out my ferns emersed. After watching the AGA video this weekend, and seeing the Senske talk, I am thinking about plumbing my humidifier into the tank. I think for their Paludarium they used cold vapor humidifiers on a digital timer set to randomly inject humidity into the tank. I have a warm vapor humidifier that I have laying around. I'll have to measure the temp, but hopefully its not to hot for tropical plants. I'm planning to eventually move everything over to my old 45 gallon tank. I'll also have to test to see what is a good schedule to set the digital timer to inject the moisture.
