What is the best direction for a greenhouse to face?
A. In our experience this is not important. With a ridge greenhouse such as the “General Purpose” Greenhouse or “Extendible Unit” greenhouse and the “Span Roof” Brick Base Greenhouses the ridge could run North/South or East/West. The old gardening books differed in their advice. Some advise that the ridge should be East/West to catch the maximum summer sun but others say run the ridge North / South to make the best of the morning sun and have the maximum shading from the framing of the greenhouse. In most gardens there is little choice and it is better to fit the greenhouse to the design of the garden. In a long thin garden the greenhouse can be used to emphasise the length of the garden or to divide the garden into areas of cultivation. The “Hexalight” and “Quadlight” Greenhouses have no main axis and this makes it easier to fit into your garden design.If you have no other constraints then the morning sun is best for the plants and the evening sun should be avoided.
