Hi
I live just outside detroit. We looked into the greenhouses but felt we would not be able to affordably heat one for this use. Believe me we would love to give em natural sunlight all year round like that. We chose to go with an actual building for all of our enclosures with sunlights. It allows natural light during the winter but also allows us to have a facility that is easy to insulate and heat.
