Greenhouses are a great way to extend your growing season and grow various plants that might not otherwise be possible in your climate. If you’re thinking about getting a greenhouse, here are ten easy steps to help you get started:
1. Select the Ideal Location.

The success of your greenhouse depends greatly on selecting the correct location. Follow these essential guidelines to ensure your plants thrive:
- Sunlight: Find a spot that receives at least 6 hours of direct sunlight daily. This allows your plants to photosynthesize and grow to their full potential. Remember that southern or southeastern exposure is usually ideal, as it provides ample sunlight throughout the day.
- Drainage: Opt for a well-drained area to prevent waterlogging and root rot. Avoid low-lying areas that are prone to flooding or areas with compacted soil. Good drainage ensures that excess water can flow away, maintaining a healthy environment for your plants.
- Wind Protection: Consider the wind patterns in your area and choose a location that provides some natural wind protection. Placing your greenhouse near a fence, hedge, or existing structure can shield it from strong gusts, preventing damage to the structure and protecting your delicate plants.
Remember, a strategic location will maximize sunlight exposure, maintain proper drainage, and offer protection from harsh elements, setting the stage for a thriving greenhouse garden.
2. Determine the Size and Design
When setting up your greenhouse, you should pick a size and design that aligns with your gardening goals and fits your available space and budget. Consider the following factors:
- The size of your space: Choose a smaller greenhouse if you have a small yard. If you have a large yard, you can choose a larger greenhouse.
- The types of plants you want to grow: Some plants, such as tomatoes, need more space than others, such as herbs. Consider the size of the plants you want to grow when choosing the size of your greenhouse.
- The climate you live in: If you live in a cold climate, you’ll need a greenhouse with a sturdy frame and a good insulation system. If you live in a warm or hot environment, you can choose a greenhouse with a less sturdy frame and less insulation.
- Your budget: Greenhouses can range in price from a few hundred dollars to several thousand dollars. Choose a greenhouse that fits your budget.
Popular greenhouse designs
Some of the most popular greenhouse designs include:
- Lean-to greenhouses: Lean-to greenhouses are attached to your house or another building. They’re a good option if you have limited space.
- Freestanding greenhouses: Freestanding greenhouses are not attached to any other structure. They’re a good option if you have plenty of space.
- Tunnel greenhouses: Tunnel greenhouses are long, narrow structures supported by arches. They’re a good option for growing vegetables.
- Soil-bed greenhouses: Soil-bed greenhouses have a raised bed filled with soil. They’re a good option for growing a variety of plants.
Careful consideration of size and design ensures a functional and visually appealing greenhouse that meets your needs.
3. Create a Construction Estimate.
A construction estimate helps you determine and project the materials, labor, and total costs.
There are a few different ways to create a construction estimate. One way is to use contractors’ estimating software. The software can help you to calculate the cost of materials, labor, and other expenses.
Another way to create a construction estimate is to use a spreadsheet. This can be a good option if you’re on a tight budget.
Remember to keep the details as accurate as possible to avoid surprises during the greenhouse setup.
Here are some tips for creating a construction estimate:
- Gather all of the necessary information. This includes the size and type of greenhouse, the materials to use, and the labor costs.
- Get quotes from multiple contractors. This will help you to get the best price on materials and labor.
- Build in a contingency fund. This will cover any unexpected costs that may arise during the project.
Once you have created a construction estimate, you can use it to secure project financing or get contractor bids.
4. Obtain Permits and Approval

When constructing a greenhouse, obtaining the necessary permits and approvals may initially feel overwhelming. However, with proper research and preparation, you can simplify the process. Follow these steps to ensure a smooth journey:
- Research Local Regulations and Zoning Laws: Start by contacting your local authorities to familiarize yourself with the specific regulations and guidelines for greenhouse construction in your area. Understanding the requirements will help you plan and gather the necessary documentation.
- Gather Required Documentation: Once you understand the regulations, gather all the required documentation for your greenhouse project. This may include architectural drawings, site plans, engineering reports, and any other documents specified by the local authorities. Be prepared to provide detailed information about your greenhouse design, location, and construction materials.
- Submit Permit Applications: With your documentation, submit the permit applications to the relevant authorities. Complete all forms accurately and include any additional information or fees required. It’s crucial to adhere to the submission deadlines and follow up on the progress of your application.
- Seek Professional Assistance: If you find the permit application process overwhelming or complex, consider seeking the assistance of a professional, such as an architect or a contractor experienced in greenhouse construction. Their expertise can help ensure your application is complete and meets all the requirements.
5. Prepare the Foundation
Depending on the design and size of your greenhouse, you have several options for the foundation. Concrete slabs are a popular choice, offering a solid and level surface.
Treated lumber can be used for more minor or temporary structures, providing a sturdy base. Raised beds are ideal if you prefer a more organic approach and want to incorporate your greenhouse into existing garden beds.
6. Assemble the Framework
This step involves following the manufacturer’s instructions precisely. Pay attention to details and ensure that all the components are correctly connected.
Enlisting the help of friends or professionals can make the assembly process easier and more efficient. The framework serves as the skeleton of your greenhouse, providing structural support and stability.
7. Set Up Irrigation, Heating, and Ventilation Systems

Consider installing drip irrigation or misting systems, which directly provide controlled and precise watering of the plant’s roots.
These systems can be automated, ensuring a consistent moisture level and reducing the risk of over or under-watering your plants. Adequate watering is crucial for plant health and growth, and an efficient system simplifies the task and helps conserve water.
Add a heating system to your greenhouse if you live in a cold climate. This will help to keep your plants warm during the winter months.
Also, even though you’ll need to heat your greenhouse during the winter, you’ll need to provide ventilation to prevent your plants from getting too hot during the warmer seasons.
8. Add plants to your greenhouse
Once your greenhouse is set up, you can start adding plants. Be sure to choose plants suited to your climate and the type of greenhouse you have.
Here are some popular plants to grow in a greenhouse:
Vegetables: Tomatoes, peppers, cucumbers, eggplants, and lettuce are all popular vegetables to grow in a greenhouse.
Herbs: Basil, oregano, thyme, rosemary, and mint are all popular herbs to grow in a greenhouse.
Flowers: Flowers such as roses, orchids, and African violets can also be grown in a greenhouse.
9. Organize and Maintain Your Greenhouse
Establish an organized layout to maximize space utilization in your new greenhouse. Utilize benches, shelves, and hanging systems to create a functional workspace and optimize plant placement.
Designing an efficient layout allows easy access to your plants and ensures you can make the most of the available space. Additionally, develop a regular maintenance routine to keep your greenhouse in optimal condition.
Even as you water and care for your plants, keep an eye out for pests and diseases and take steps to control them as soon as possible.
And finally…
10. Enjoy your new greenhouse!

Conclusion
Setting up a greenhouse can be a lot of work, but it’s a rewarding experience. You can have a beautiful, productive greenhouse for years with little planning and effort.
