Hi guys, apart from the 'ol frozen coke or milk bottles, is there a more up-to-date method of temp control, maybe in the form of a thermostat or something along those lines?
I've read the idea of using a Aquarium thermo but wasnt sure if this was the only tried & tested method.
Looking for something relatively cheap at this stage, if not then I'll just stick to the coke bottle method for now!
