How To Build A DIY Dome Greenhouse

Building a DIY dome greenhouse can be a rewarding project that provides a great space for your plants to thrive year-round. Here’s a straightforward guide to help you get started:

Materials Needed:

  1. PVC Pipes: For the frame of the dome.
  2. Connectors: To connect the PVC pipes together (you may need various shapes like T-joints and elbow joints).
  3. Polycarbonate Sheets or Heavy-duty Plastic Sheeting: For the covering.
  4. Zip Ties or Metal Clips: To secure the covering to the frame.
  5. Door Hinge and Latch: For creating a door.
  6. Tools: Including a saw for cutting pipes, a drill, and possibly a staple gun.

If you want to take a few shortcuts then grab a pre-made geodesic frame and a plastic covering.

Steps to Build a Dome Greenhouse:

  1. Design Your Dome: Determine the size of the dome and calculate how many pieces of PVC pipe you’ll need. There are dome calculators online that can help you figure out the exact specifications for a geodesic dome.

  2. Cut and Assemble the Frame: Cut the PVC pipes to the required lengths. Connect the pipes using the PVC connectors to form the dome structure. Make sure your dome has a solid base and evenly distributed panels.

  3. Cover the Dome: Once your frame is sturdy, cover it with polycarbonate sheets or heavy-duty plastic. Cut the material as needed to fit the dome’s panels. Secure the covering to the frame using zip ties or metal clips. Ensure that the plastic is taut and secure to minimize any flapping or tearing due to wind.

  4. Install the Door: Fit a door frame at one of the hexagonal or pentagonal openings using additional PVC pipes and connectors. Attach polycarbonate or plastic to the door frame and secure it with hinges and a latch.

  5. Seal All Gaps: Check for any gaps or openings where air might escape and seal these with extra plastic, silicone, or weather-stripping. This step is crucial for maintaining humidity (1) and warmth inside the dome.

  6. Ventilation: Consider installing manual or automatic vents in the top and sides of your dome to manage temperature and humidity.

  7. Final Touches: Add interior shelving or planting tables as needed. You can also install irrigation or misting systems to help with watering your plants.

Tips:

  • Location: Choose a spot that gets adequate sunlight and is protected from strong winds.
  • Maintenance: Regularly check the structure for any damage or wear, especially after extreme weather conditions.
  • Enhancements: Consider adding solar panels or LED grow lights for energy efficiency and extended plant growth cycles.

Building your own dome greenhouse can be a bit of an adventure, and it might take a bit of trial and error to get everything just right. But once it’s up, it can be a fantastic, functional space for gardening.

Pros And Cons Of Dome Greenhouses

Here are some of the pro’s and con’s of dome greenhouses.

What are the pros of dome greenhouses?

Efficient Energy Use:The shape of a dome greenhouse allows for the even distribution of heat and light, minimizing cold spots and shadows within the structure. This can lead to lower heating costs in colder climates and more efficient use of solar energy.
Strong and Durable:The geodesic design of dome greenhouses provides natural strength and the ability to distribute structural stress evenly throughout the shape. This makes them particularly resistant to challenging weather conditions such as strong winds, heavy snowfall, and hail.
Optimal Air Circulation:The curved surface of a dome encourages better air movement and natural ventilation. This helps maintain consistent temperatures and reduces the risk of plant diseases, which are often exacerbated by stagnant air.
Maximal Sun Exposure:The dome’s shape ensures that sunlight is more uniformly distributed throughout the day. This is especially beneficial for plant growth as there are fewer direct sun or deep shade areas, which helps reduce the growth of algae and mold.
Space Efficiency:The circular design eliminates wasted space common in traditional square or rectangular greenhouses. This makes it easier to set up plant arrangements and maximizes usable growing space.

So those are all the exciting things that you can expect from owning a geodesic dome greenhouse. Here are the cons.

What are the cons of dome greenhouses?

Complex Construction:Although the end result is highly efficient, constructing a geodesic dome can be more complicated than building traditional rectangular greenhouses. The geometric design involves numerous triangular panels that need to be precisely sized and assembled, which can be challenging without the right tools and expertise.
Cost of Materials and Construction:Due to their unique shape and the need for specific materials and connectors, dome greenhouses can initially be more expensive to build compared to standard greenhouses. Specialized components like custom-made hubs or specific types of coverings can add to the cost.
Temperature Control:While domes distribute heat and light evenly, their volume can make it harder to control temperature and humidity, especially in larger domes. This might require more sophisticated ventilation and heating systems.
Limited Expansion:Unlike traditional greenhouses that can be easily extended by adding more structure at the ends, expanding a dome greenhouse is not as straightforward and often requires building a new or entirely separate structure.
Condensation Management:The shape of the dome can lead to water dripping from the center of the structure onto plants below, which could potentially cause disease or discomfort in humid conditions. Managing this requires careful placement of plants and possibly additional water diversion tactics.

What is the difference between a greenhouse and a growing dome?

A greenhouse and a growing dome are both used for growing plants, but they’re built differently.

A greenhouse is usually rectangular and made with materials like glass or plastic to let in a lot of light. It’s a common choice for gardeners because it can be built in various sizes, and it’s pretty straightforward to expand if you need more space.

A growing dome, on the other hand, is shaped like a half-sphere or dome. This shape helps spread light and heat more evenly inside, which can be better for plant growth. Growing domes are also really strong and can handle harsh weather better than the typical flat-surfaced greenhouses. However, their curved shape can make it a bit harder to set up your plant shelves and requires a bit more effort in construction and layout planning.

So, the main differences come down to their shape, how they handle weather, and how you arrange everything inside.

Conclusion:

Whether you’re just starting out in gardening or you’re a seasoned green thumb looking for a more robust solution, a dome greenhouse might just be what you need. With their unique geodesic design, these greenhouses offer efficient energy use, strong durability, and optimal conditions for plant growth, making them a smart investment for anyone serious about gardening. However, be prepared for a bit more complexity in setup and potentially higher initial costs compared to traditional greenhouses.

Ultimately, choosing between a dome greenhouse and a more conventional style boils down to your specific needs, budget, and how much time you’re willing to invest in setting up and maintaining your gardening space. With the right choice, you can transform your gardening experience and enjoy a lush, productive garden all year round.

FAQs

Are dome greenhouses good?

Yes, dome greenhouses are quite beneficial, especially for efficient energy use, strength under adverse weather conditions, and maximizing space with their unique design. They provide even sunlight distribution and good air circulation, which are great for plant growth. However, they can be more complex and costly to set up compared to traditional greenhouses.

What is a greenhouse dome called?

A greenhouse dome is often called a geodesic dome greenhouse, referring to its specific structural style that uses a network of triangles to form a roughly spherical surface.

How much does a geodesic dome greenhouse cost?

The cost of a geodesic dome greenhouse can vary widely based on size, materials, and features, but generally, they start around $1,000 for basic kits and can go up to $25,000 or more for large, high-end models equipped with advanced features.

Do geodesic domes leak?

Like any structure, geodesic domes can leak if not properly assembled or maintained. However, their design doesn’t inherently make them more prone to leaks. Proper sealing, regular maintenance, and using quality materials are key to preventing water ingress.

Why are geodesic domes not popular?

Geodesic domes are not as popular as traditional greenhouses mainly due to their complexity in design and construction, higher initial costs, and the challenge of fitting standard greenhouse accessories like shelving inside a curved structure. They also require more specialized knowledge to design and build effectively, which can be a barrier for average gardeners.
