A little tweaking and it is perfect! This green house is a great buy for the money! You get a couple extras the others don’t offer! The temperature controlled opener is great if you cannot be around all day. The shelving is the perfect size to use flats that you get in the garden stores. There is not a shelf along the rear of the green house, however I called the manufacturer and for about $30.00 you can purchase extra parts to assemble one. To lessen confusion about the panels, I would recommend that you mark the outside of the polycarbonate panels as you remove the protective film. Do this as you need the them, because the part number is on the film! The tweaking would be on the pre-assembled doors. The corners are held together by a plastic elbow; if the wind catches your door and throws it back they are broken. The manufacture sent replacement parts no questions asked. We put small metal L shaped braces on every corner, and we haven’t had any more problems. We actually anchored the greenhouse into concrete, It has withstood winds up to 50mph and hail so far! I tell everyone about my green house and how much I love it!
