Last year I modified an old refrigerator with a new thermostat so that I could set the temperature to 50F, which is optimal for some lilies (the cool hypogeal group) and Pacific Coast iris. I've run it for a year now, using it for this dedicated purpose. May I suggest that when bulbs need cool storage, and if you have room for a dedicated refrigerator, you try this, dialing the thermostat to the right setting to keep bulbs in the 40 F, or whatever their optimal storage range is?
