When decarboxylating your cannabis in an oven, it’s important to remember that the temperature dial on an oven is more of an average temperature than an exact one.
Ovens can fluctuate in temperature by 20 or more degrees, so keep an eye on your cannabis. If it turns brown too quickly or smells like it is burning, turn the oven down. An oven thermometer is a good investment if you’re going to be using your oven regularly for cannabis cooking.
