Thank you for the wonderful greenhouse plan! Since I live in the northern states,
I stepped it up and insulated the base and used twin wall polycarbonate for the windows.
This should extend my growing season for all but the two coldest months.
I also extended the length to twelve feet, but left the width at 8 feet.
I extended the rafter tails so I can add eaves to collect rain water.
There is a double window on the end opposite the door for ventilation.
I appreciate your site. Thank you so much.
