ok so i bought a new digital hygrometer/thermometer last night, and set it up this morning, my old gauge (not digital was reading 40 dry and got up to 70-80 when misting) the new one though read 20 dry, 20 while misting and didnt even change a bit, moved it to the adjacent side of the cage, 30 dry, and raised to 37 after a nice long mist, was my old gauge off that much? or do digitals take some time in the cage to get adjusted....and if it is correct and my humidity is getting that low, some tips for raising it?? (have 2 sides of cage blocked off with a shower curtain, mist 3-5 times a day depending, bout 5 mins each)
