A lean-to greenhouse, also known as a wall greenhouse, is designed to make use of an existing wall. The greenhouse extends out from the building with the building wall acting as one of its sides (or more accurately it’s back). A lean to greenhouse is usually built on the east or south sides of a home in order to get as much sunlight possible.
A lean-to greenhouse is a great choice if you have limited space for a full greenhouse and want to extend your growing season despite the outdoor weather conditions. I will be reviewing three popular lean-to greenhouses on the market.
