This Greenhouse is AMAZING for a first time buyer. To make it A LOT more sturdy I added a 5'x5' base and added brackets to bolt it down to survive Michigan's weather. So far it's survived a rainstorm and wind storm and its still standing :-D. It keeps the temperature and humidity really well. The shelves aren't the best but they can hold a humidity tray pretty well. I would DEFINITELY buy this again!
