Drying psilocybin truffles is pretty simple! Once you have harvested and washed the truffles, cut them into small pieces with a clean knife to avoid any risk of contamination. Then, spread them out on a tray lined with parchment paper. Make sure that the pieces of truffle are well spaced out to allow for adequate air circulation. Finally, place the tray in a warm and dry location, avoiding direct sunlight which can damage the mushrooms. Turn the pieces of truffle over every day to optimize the drying process. When they are completely dry, which should take about a week, place them in an airtight container and store them away from light. If you want to speed up the drying process, you can place a dehumidifier nearby.
