Yes, I have a greenhouse for almost 15 years now. And I love it. I ordered it from a company that had a display at a big flower show in Philadelphia, PA. It's 2-ply plastic and not at all energy efficient. It has a propane heater, and I used to heat it all winter, (for houseplants) but when prices went up I could no longer afford that. Now I heat it in March to start seeds. I love growing seeds and plant them in my yard. As well as giving some plants to friends. Rejoyce >
