We live in a townhouse and needed some protection for our larger trees during the winter. This greenhouse is large, good quality and easy to put together. Plenty if racks and we really like it. We found that it maintains a very humid environment, which can be good and bad depending on what you're trying to grow. Now that the winter is here, there isn't as much moisture/condensation, but just before the winter there was a lot--too much for some of my plants. There are ways around that, you can cover those plants that require less moisture and it has great ventilation if you need to open it. Would purchase again. I grow everything from small trees to flowers and herbs. Can't wait to start my seeds in it.
