I love this greenhouse! It's my first go at trying to keep some of my house plants growing through the winter and so far things are growing great! I live on a 3 floor apartment with a small deck. The greenhouse was just the right size for set up. Which was quick and easy! The shelves are surprisingly sturdy. I just used a little twine to keep them from sliding. Because I was up so high the draft was very cold but with a rug and a small heater it's very warm! Only concern is sometimes it gets to humid because there are no windows. A fan helps but I've gotten by so far without it being to bad. Just watch out for that!
