There are two ways to dry magic mushrooms—air drying and using a dehydrator. Air-drying mushrooms will take longer—about 1 to 3 days.  To do this, place the mushrooms in an environment with a temperature of 60 to 70 degrees Fahrenheit and humidity of between 55 to 65%. Place the mushrooms in a wire rack for even drying. If you don’t have one, you can simply place them on a clean cloth but make sure to flip after every few hours. On the other hand, you can dry mushrooms faster using a dehydrator. However, you would need to monitor them closely since the performance of every dehydrator is different. To stay on the safe side, set the dehydrator to a low temperature and check the mushrooms every 15 to 30 minutes.
