Pre-heat oven to 240°F (116°C).
Break apart any large buds by rubber them up between your hands or use a grinder or food processor (to save time).
Spread out over a baking pan to fit nicely and give it a shake to toast evenly throughout.
Place in the oven. Keep an eye to figure out the way your oven works the first time you decarb cannabis. Take a peak after 20 min, 30 and 40 to 50 minutes till it gets from vibrant green to nice toasted golden brown. Avoid opening the oven all way down.
Remove and allow to cool completely. Use immediately or store in a mason jar or airtight container in the freezer or cool, dark place up to 2 months.
