Hi begginerblazer

Crock pots as a general rule seldom advertise their higher and lower temperature ranges due to the standardised nature of how they operate.
i.e. They're designed to 'slow cook' foods (stews, casseroles etc) at just below boiling point.
Therefore, the assumption is a typical temperature is about 100 degrees Centigrade or 212 Fahrenheit.

I looked up the model you list (the Rival 5025-WG), and you'll be just fine with that.
Remember though that under normal operating conditions the crock pot is usually 'filled' with liquid, vegetables, meats etc, and so when we cook with just oil in them they can get a little too hot on the 'High' setting.
I would expect a model like this one to creep as high as 150 centigrade or 300fahrenheit, so my advice would be to use the 'high setting' for about an hour to get it started before switching down to 'low' for about one and a half to two hours (assuming of course that you don't own an oven thermometer in order to monitor the temperature). Overheating the THC will reduce the potency as it causes it to vaporize.

Anyhow, good luck and come back to let us know how you get on or if you have any other questions.
