Cold Storage Container -- thermostat
I'm in the process of designing an insulated box which I can keep in my garage over the winter and in which I can place my tender bulbs, tubers,... - begonia, canna lily, gladiola,... I'm planning on placing a heating cable in the bottom of the box and installing some type of thermostat that will keep the temperature between 5 and 10 Celsius. Would any of you have any experience with this type of unit such that you could offer some advice on the type of thermostat to use. It has to be cheap and durable, ideally some type of bi-metal device. If you are aware of what might work best would you also know where I can purchase one?
