Brnedan, can the silica gel be microwaved to save on the baking time? I'd certainly not be keen to leave an oven running overnight.

Once the oven reaches the desired temp. and with door is closed, the heating element will only come on for very brief periods to maintain the temp.
Not sure about µwave ovens. High settings would probably crack the granules as the water rapidly evaporates. Low settings are just high power bursts with off times in between, but might be worth experimenting with.
Some granules come coloured with cobalt chloride that changes from pink when saturated with water to blue when dry.
