How to change moisture level? Simple!
GAIA comes pre-set to the perfect moisture level to your plants (you can tell us about your plant type while purchasing and we will pre-set it to the perfect level for you). Further, if you'd like to change the moisture level yourself should you switch plants, you can easily do so by taking off the plastic casing, and change the switch to one of the settings (low, medium, or high). Then put the casing back on, and GAIA is ready for your new plant!
This is how it looks like when the casing is off
