yea humidity shouldn't kill
succulents but over watering will... here in Central Texas i gorw alot of cacti and
succulents indoors and outdoors during the
spring the humidity levels can reach 80% or more almost tropical... because of the torential and non-stop rain(like this weekend, non-stop foggy/ misty conditions with a few thunder storms)... i keep them protected from the rain but the humidity is MUCH higher than what they normally encounter... but indoors during winter when central heating is used and humidity levels can SORTA be influental... i pot my
plants in quick draining medium and in terra cotta pots... the
succulents should be wet for too long its ok to water every 3-4 weeks but DO NOT let the soil remain wet/ damp for a week thats a killer situation... my
succulents medium dry out anywhere from 1-2 days PLENTY of time to absorb water BUT not enough time to rot...
