i need some ideas to help raise my humidity i cant seen to get it above 35% and that's right after i mist and with a water dish i have a 20l tank with a screen top that is covered about 75% with foil, i use aspen as a substrate im currently running a 75W day time heat lamp i get my temps where they should be hot cool and ambient i do not have a uth at the moment bacuase i havent purchased a thermostat to run it. everytime i come home from work the water dish is empty from the lamp evaporating all the water. if i switch from a bulb to a ceramic heat emitter would this help?
