That's what I started with, I still have it. I used it in the house, I got some cheap flourescent lights and attached them to shelves and used them in the house at first. Now I use it on my front porch to harden my plants. It orignally came with a plastic cover which is in pretty rough shape after all these years. Last year I bought another one that I use on the patio and it has a nice cover (because it's new). I start my plants inside under lights, move them to the greenhouse on the porch which is shaded to hardened them then they go to the greenhouse on the patio which is in the sun and covered to keep the heat in until they can go to the garden.
I just got a real greenhouse and I am going to move my new one into the greenhouse so I can have the shelves and the cover. I really like both of them and like I said I have had it for years. I hope you enjoy your greenhouse.
