Thank you for sharing your pictures and benefits of overwintering indpprs. Living in central Florida I do not have a lot of overwintering problems and I have little cages made out of PCV pipes that are easily asembled and disasembled that I cover with plastic and use Christmas lights inside for heat. It works like a charm. For extra pots I place platic on a PCV pipe base on my screened in back porch and use a space heater if the heat from the walls of the house is not sufficient. I keep a thermometer out there to check the temps. I love your ideas and thinks others should try it.
