Firstly, you’ll want to start by decarboxylating the cannabis. You can do this by preheating your oven to about 120º C (220-240º F). You can then place the cannabis, broken down and scattered, on an oven-ready tray. Place the cannabis inside of the oven for about 10-15 mins. Remove and let it cool. I personally like to place a bit of aluminum foil loosely over the cannabis to ensure to trap in as much of the essential oils evaporating.
