Build your own solar greenhouse using this solar greenhouse design and construction diagram that will create a homemade greenhouse with optimum light for plant growth.
The greenhouse design guidelines that follow are for the design of a solar greenhouse where light, not heat, is the limiting factor for plant growth.

A solar greenhouse is different from a sunspace. One is designed to suit the needs of plants, the other those of people. A solar greenhouse is a pleasant place to visit, and it helps heat the house it's connected to, but these aren't its primary purposes.
The solar greenhouse design guidelines that follow are for the design of a solar greenhouse where light, not heat, is the limiting factor for plant growth. A greenhouse built to these parameters will require a small amount of back-up heat to maintain optimum growing conditions. Still, it will provide more energy to the house on an annual basis than it will require for occasional auxiliary heating.
