Do they make a temp controller that will automatically ramp up temp?

Do they make a temp controller that you can set to ramp up the temp after however many days you set? Or do you always have to do this by hand?

Seems like a good idea, however I really like to be able to monitor the temp of the wort that way I know that I am increasing the ambient temp at the right time. Sometimes the wort is 2-3* over ambient temp and other times they can be 10*, so this could be a factor that would come into play. But my temp probe measures the ambient temp. If you had one that measured the wort then it could work. I wonder if you could create a computer program that could do this for you...

Look for ramp/soak PID controllers. Watlow makes em. Pricey, but nice.

Auber Instruments makes one for 60-70$ I believe. It's got full ramp soak options on it.
