Grow dep green houses

[High kev]

I’ve been trying to research a good green house for the back yard I can add an auto light dep system to it. Was wondering if anyone out there had any good or bad experiences. Or any tips on buying or building one. It would be cool to have a all year round greenhouse. But that would be a challenge for the winters here in upstate ny

Most of the companies that I know of are over on the west coast. The farm I worked on had greenhouses from emerald kingdom in redding, ca. They were easy to put up. It took three of us 2 days to put up a 70' x 12' iirc. There are ways to install to take advantage natural thermal buffers to make usable in winter for crops at least. Weed in winter in a greenhouse in upstate New York would be cost prohibitive I would think.
