Greenhouse Plans

*greenhouse

A greenhouse is one of the most well-known garden structures. Providing shielding from extreme sun, wind, and rain — greenhouses can significantly extend your growing season.

These sunny buildings come in a variety of shapes and sizes too. Heated glass greenhouses can fight against snow and cold in severe climates. Plastic sheeting can help create an impromptu structure to save a raised bed from unexpected frosts. Paneled greenhouses can help maximize or minimize UV rays depending on the material.

Whether looking for a lean-to DIY or a larger farm-scale design, there’s a greenhouse option for just about everyone. Check out some of our favorite designs and styles to help you build a greenhouse of your own.

Glass Greenhouses

Glass greenhouses were the only choice prior to 1950, and are still popular today. Glass offers a more permanent and weather-resistant structure, as well as lower relative humidity and less disease. For more information on glass greenhouses, Colorado State University offers an excellent presentation here.

Corrugated Polycarbonate Greenhouse

Polycarbonate is an extremely durable plastic, in fact, you may have heard of it when purchasing impact-resistant safety glasses. Greenhouse experts like Grower’s Supply recommend this material for both its durability and its eco-friendly impact.

Polycarbonate panels are recyclable. They come in multiple colors and strengths, with a UV resistant clear panel being most common in greenhouses.

Currently, polycarbonate is super long lasting, but not recyclable. We hope that as technology advances, new plastic treatments will help create additional environmentally friendly opportunities.

Too often, plastic greenhouses are used in a very non-eco-friendly way—people put them up, find they aren’t durable enough, and end up chucking pounds of plastic into a landfill.

If you go with plastic, find something durable. If you really do want something temporary—say, just a cover to protect against frost—look for recyclable sheeting to reduce waste upon tear down.
