This system is great and is perfect for the small terraced yard we have. The only downside is the size of the planting areas. When planting, we discovered it was easier to fill each row with soil, then plant, then top off and fill the next level. Because it is an open system in the middle, it makes planting difficult when it all full. Also, I would recommend getting smaller plants that are 6 per pack instead of one larger tub because the larger tub plants were a tight fit. 

We also put the system on wheels so that it can be moved to different locations in our yard depending on the amount of sun. We got the wheels from amazon. So far we love it and cant wait to use it!
