I received this greenhouse to review and I AM IN LOVE! I cannot tell you how much I absolutely ADORE this greenhouse. It has PLENTY of room for all types of my veggie plants. Fits nicely inside our classroom with MORE than enough room for all of our students plants too. It was ridiculousy simple to put together. It took me about 2-3 minutes. The shelves are very sturdy. I cannot say enough good about this product. If I had the $$ I would buy several of them!
