What is a Porch Greenhouse?

A porch greenhouse is a small structure or extension attached to a home, typically located on a porch, that is designed to provide an optimal environment for growing plants. This type of greenhouse allows for easier access to gardening while maximizing space and utilizing the warmth provided by the home.
