Robin - Yes, alternative would be running a second refrigerator. In it, I'm incubating about 15 lily collections, some are small batches from PBS seed exchange, others larger for production. My first attempt at this scheme! Fall planting has not been reliable and timing difficult. This seems like best solution for small lots. The box is glued together 2 inch styrofoam and has light source if needed. Can be scaled down to fit a normal refrigerator. The walk in cooler is 12 x 12 x 8'. We need the lower temp range for cold stratification and actually by next month will be 36 degrees. . Heated box is size of large camp cooler and heat source regulated by thermostat is minimal. Energy 'cost' is considerably less than setting up another refrigerator to maintain 48 F. Also I have option to include additional temp ranges with light sources if needed in same cooler.
