I tend to view everything from the lens of tropical plant because I am a tropical gardener. My greenhouse is specifically used to grow tropical plants that won't survive in my zone outdoors, or would survive but get knocked back.
The Atlanta cool house was designed to be a cloud forest greenhouse to grow cloud forest epiphytes and other plants, orchids, ferns etc that have to have a narrow range of cold to cool temperatures while still having extremely high humidity to thrive. Supposedly its the only greenhouse of its kind in the US
