Keeping temp down

[testtube]

You have a temp. probe in your fridge (or wort) attached to a temp. controller with heating and cooling like atc800, connect fridge to cooling circuit and greenhouse heater to heating circuit and hey presto! it does what ever is needed, ie maintain a certain temp.

So ideally i need a working fridge, Temp Controller and one of those white heatery things. ummmm sounds doable how much does a temp controler set you back, off to e-bay
