Ron, I'm just north of you in Michigan and with our "dry" winters, it is somewhat difficult to increase the humidity without misters or a humidifier. It is true that as your collection increases in size the humidity will naturlly increase as well as following a goodd watering...common sense! I have a real problem keeping the humidity up even with wetting the floor and benches and misting the plants...but they survive and even flower for me....enjoy your beautiful new GH
