Every year I buy plants, and every year I kill them. I just don't have green thumb, but I really like flowers. So, this year I decided to buy seeds. That way when I kill them, I'm not out as much money. Since it still drops into the 30's here at night, I knew I needed something to protect them from the cold. I purchased this 3 shelf greenhouse from Target because I didn't need anything too bid. It was very easy to put together (10 minutes) and that afternoon I had my seeds planted, watered, and nice and cozy inside their new home. That first night it got really cold but the book said that it would stay 10 - 15 degrees warmer inside the greenhouse. I was keeping my fingers crossed. It's now been a week and guess what? I have green plants popping up. I actually did a happy dance. My only complaint with this unit is that it's very light. I don't know how well it's going to hold up in the wind. We live out in the country and have some pretty big gusts. We have it anchored down the best we can and I hope it's enough. But for now, I am very happy with this product!
Update On Apr 17, 2008: This did blow over in the 45 mph winds we had the other day. However, I picked it up and moved it to another spot in the yard and it was fine in yesterdays winds.
