The best orientation for a greenhouse depends on the specific characteristics of your location and the sun’s path. By aligning your greenhouse with the sun’s path, you can optimize sunlight and maximize your yield. When choosing a location and orientation, consider environmental factors and structural needs to create a greenhouse environment that is not perfect square. The best place to position your greenhouse is typically one that gets lots of sunlight (with southern exposure), very little wind, is slightly elevated, and not located in a hollow.
For optimal greenhouse positioning, position the greenhouse with the longest side facing true south to maximize sunlight exposure throughout the day. Leave at least 25 feet of clearance around the greenhouse. For those interested in fall, winter, and spring greenhouse gardening, an orientation in an East-to-West manner is more suitable. Proper planning and thoughtful design are essential for achieving the desired greenhouse environment.
The most optimal greenhouse position is for one of its longest walls facing south or within 20 degrees of south. Assess your garden’s conditions, avoid tall trees, give your greenhouse breathing space, make it easily accessible, and ensure child safety. Hoop house orientation can be north to south or east to west.
We don’t recommend building the greenhouse without adequate southern exposure, as most customers choose to orient their greenhouse in a south-north direction. If living in an area with extreme winds, position the greenhouse in a south-north direction if possible.

Where not to put a greenhouse?
Place a greenhouse under tall trees to reduce sunlight and prevent glass damage. High walls, hedges, and trees can serve as windbreaks, providing shelter without blocking light. These barriers keep plants warm and prevent wind damage during storms. However, it’s important to ensure the trees are a suitable distance to provide shelter without blocking light. Providing ample room for cleaning and maintenance is crucial for maintaining a healthy greenhouse environment.
Is it OK to put a greenhouse in the shade?
Plant growth relies on light, so only the minimum amount of shading is needed to maintain temperatures below 25-27ºC (77-81ºF). However, allow as much light in as possible, especially for edible plants like tomatoes. Sun-loving plants like succulents don’t need shading, but providing shade can make the greenhouse more pleasant. There are various ways to shade greenhouses and conservatories, including external blinds, which provide shade and a cooling effect by preventing sun rays from passing through the glass, and internal blinds, which allow sunlight to pass through the glass and generate heat but are more easily automated. There are various materials available with varying degrees of shading and permeability to allow air exchange.
How to maximize sunlight in a greenhouse?
To optimize greenhouse lighting, consider the following factors:
- Ensure the greenhouse is positioned to receive maximum sunlight, with south-facing orientations being most effective in the Northern Hemisphere. Minimize obstructions like trees or buildings.
- Use light-transmitting materials like glass or polycarbonate for high light transmission. Regularly clean the coverings to prevent dust buildup.
- Install light-diffusing materials or shade cloths to ensure even light distribution.
- In regions with limited sunlight or winter months, supplement natural sunlight with artificial lighting like LED grow lights. These energy-efficient lights mimic the intensity and duration of natural sunlight, promoting healthy plant development.
Should you open your greenhouse every day?
Greenhouses are designed to absorb heat, which is beneficial for plants. However, too much of this heat can be harmful. To maximize ventilation, it is recommended to leave the door wide open or ensure multiple vents are unblocked. A simple rule of thumb for greenhouse ventilation is to ensure at least 20 of the total floor area can be opened. This means that one-fifth of the floor size should be “openable”, and smaller greenhouses may need a higher percentage. This ensures that the greenhouse is well-ventilated and provides adequate warmth for plants.
What is the best surface to put a greenhouse on?
Concrete is a popular choice for greenhouse flooring due to its durability, ease of cleaning, and customization. However, it can be difficult to install and repair after the initial build, and lacks insulation, making greenhouses hotter in summer and colder in winter. Paving stones, on the other hand, are durable, easy to clean, and come in various colors and styles. However, they can be expensive and require regular maintenance to maintain their appearance.
Which direction should you face a greenhouse?
The optimal location for a greenhouse is one that receives an abundance of sunlight, regardless of the structure’s orientation. The majority of customers select a south-north orientation, as this configuration ensures that the requisite sunlight is available for their plants.
Should a greenhouse be in the sun all day?
Greenhouses should be placed in areas with uninterrupted sun and protection from cold winds to promote plant growth. Wood is a popular material for glasshouses, with a natural metal or painted finish. It requires no upkeep and produces minimal shade. Wood is a traditional building material, suitable for some garden styles but requires periodic maintenance. Wooden frames are bulkier and can cast excessive shade. The height of the eaves at the eaves is crucial for light transmission and plant growth. A minimum of 1. 5m (5ft) tall eaves is recommended, with a maximum of 1. 8m (6ft) or more.
What should a greenhouse sit on?
The foundation for a new greenhouse is dependent upon the specific location and the individual’s preferences. The construction materials that can be used for the base of the greenhouse include slabs, concrete, or bare earth. However, it is recommended that slabs be laid on a level surface, ideally using a sand and cement mixture. In the event that a slabbed or concrete area is already in place, no further action is required. The optimal foundation and base for a square, level greenhouse is a level one.
Do greenhouses need to be south facing?
Large greenhouses should be facing east-west, with the door at the western end, to fully expose them to the sun from the south, especially during winter when it captures more light. This orientation is best for over-wintering tender plants. North-south-facing greenhouses with doors at the south end benefit from summer sunshine but not the full force of hot midday sun, making them ideal for growing crops like tomatoes, cucumbers, and peppers.
Does it matter where you put a greenhouse?
To maintain a greenhouse’s interior temperature and reduce storm damage risk, consider wind direction and force. Place the greenhouse in a location where it won’t be subjected to severe winds, and if needed, plant a hedge or install slat-style fencing 15 feet away from the structure. Avoid dense plants and solid fences, as windbreaks can increase the speed and force of the wind. Remember your greenhouse needs, such as water, and determine the best location for your water source. Determine if you plan to use pipes underground or a hose, and if you plan to use electricity, make this decision ahead of time to avoid issues during the structure’s installation.
