So you will set up easy access for mice and rats to come into your house through ductwork? I like that idea very much and see no problems with it. Are you familiar with the temps a greenhouse needs for vegetables to grow and produce (not just stay above freezing) I don't think you will be capable of heating it to that temp. Then you will have the underground greenhouse in the shade next to the garden. How much heat will be required to heat that to a temp capable of vegetables producing? I don't think you have thought this through. You are relying on the ground temp being 50 degrees but neglect to factor in the extreme temps on the roof at night and even most days in the winter. Well it will serve you well as a trash pit the second year since it won't work as planned. Just trying to help.

@troyreidlies.................... AGAIN ,HIS OWN WORDS...................I plan to grow sensitive plants in the multiple greenhouses. The one by the house will be heated by air from the house itself through ducts. This will be more of an all year greenhouse then. I take it to mean since he has a climate different than anyone else there , that the air surrounding his greenhouse which he plans to bring into it by duct work must be almost tropical in nature to enable him to grow the MOST SENSITIVE PLANTS year round ................AGAIN HIS WORDS TAKEN FROM HIS STEEMIT COMMENT
