I leave mine out.... I've been a modulus user for 22+ years and haven't thought about humidity until recently as I've started buying wooden-necked instruments again.
But, Hercules will tell you not to leave a guitar on their stands. I've ignored that but then a funny thing happened. My stands are themselves really old. One day I went to my music room and grabbed my main modulus Q5 and the neck of the stand fell through the bottom stand to the floor. The post slid all the way down. Inspecting the hand grip showed the plastic had failed.... The only thing holding the bass up was a pin or screw of some kind, the weight of the guitar pinched it in place. Lifting the guitar released the broken pieces to the floor.
The Internet told me there was a bad batch of stands so I contacted Hercules and they gave me a replacement, all I had to do was give them photos of the parts... The tell-tale sign that my stand was one that was failing was that the plastic grip was getting gummy and wet looking.
Anyway, I didn't learn a lesson here, I still keep my bases on stands. But, sometimes I at least now think about putting them away where before the thought never crossed my mind.
