Message: <blockquote data-quote="Dave Jay" data-source="post: 143370" data-attributes="member: 27677">Humidity itself is a measure of the amount of moisture in the air which will vary depending on the humidity in your home and the temperature at the time, trying to maintain a certain number is futile really. To a certain extent it can be raised or lowered by varying the amount of available moisture present and by adjusting the ventilation, you are limited by the ambient relative humidity in your home and by the temperature though so it will always vary no matter how often you make adjustments. What you're taking readings of is the relative humidity of the air in the enclosure, it doesn't really reflect the humidity in a burrow. With a false bottom you usually have as much ventilation as possible and the animal adjusts the burrows humidity by varying the depth of the burrow and it's position in it, the ambient relative humidity in the enclosure has little influence on the depths of the burrow unless it's very extreme. For this reason I like to use a false bottom for animals that suffer if the humidity is too high, the surface and most of the substrate is dry but they can follow their natural instincts and burrow deeper if they require a higher humidity in the burrow or sit higher in the burrow or on the surface when they don't.Like you though, I also use it for animals requiring a high moisture/humidity level, adding water to the bottom is better than flooding the top all the time which gives the animal no choice at all and promotes fungal and mould problems.</blockquote>
