Here is my new cable-heated bench for getting my tomato starts off to a strong start. 100′ of heating cable on a 3×12′ bench. An Inkbird C206 thermostat controls Redi-heat 8554 cable.
[Update 4/5/2017] Sadly, the heating cables stopped heating after only one month in use. The thermostat continues to work well, so it now powers two 150W heat lamps.
