I eat organic produce and want to build a greenhouse. What type of material is best for my greenhouse? I don’t typically like to use plastic and I wonder if it is safe for my vegetables for the sunlight to come through the plastic windows, would it emit anything unfavorable?

There are a wide range of materials used for greenhouses, especially when it comes to growing vegetables. Common ones include glass, acrylic, polycarbonate, and polyethylene, some of which are used in certified organic production. This guide from University of Georgia ( provides a very good overview. For the backyard, you might look at smaller high tunnels and coldframes to begin with. Keep in mind too that many vegetables will need pollinators so you may not be able to grow all your vegetables in a greenhouse.
