Geodesic dome greenhouse- Food all year round!
As a passionate foodie and grower I wanted to create the environment where I can grow medicinal herbs and vegetables all year round, and when I got the allotment plot in October last year at Thornton Allotments, I have been over the moon ever since as i was allowed to use it as Permaculture demonstration plot.
Why Geodesic Dome?
I decided to build a Geodesic dome greenhouse, as thanks to its design, has much more functional advantages, when comparing with a regular one. It has robust and durable structure, even in harsh climates; it benefits from energy efficiency with minimal heat loss thanks to spherical shape; air moves freely and evenly inside the dome. It is also an eye-catching construction, embellishing any garden and a peaceful sanctuary, perfect for relaxing.
During my landscape architecture studies I developed great fascination with sustainable design structures and therapeutic gardens inspired by nature and this is when I came across Buckminster Fuller, American architect, mathematician, engineer, philosopher, historian, and poet. Thanks to Fuller, geodesic domes earned their spot in the limelight back in the 1940s and 50s. He saw the value in geodesic domes and envisioned a future where people lived in domes rather than rectangular homes. Although Fuller’s vision hasn’t come to fruition, we can take his knowledge and use it in our gardens as the same benefits he saw for housing also apply to greenhouses.
Geodesic domes are created by connecting triangles together in a dome shape, using precise angles and measurements. The triangular elements of the dome are structurally rigid and distribute the structural stress throughout the structure, making geodesic dome able to withstand very heavy loads for its size.
Geodesic domes are also impervious to the strongest winds. Because there are no large surface areas for the wind to push against, air just flows around and over the dome. Snow builds up on the roof of rectangular greenhouses, but just slides off domes.
Another advantage of geodesic dome greenhouses is their energy efficiency. The dome shape has 30-40 per cent less surface area for the floor space enclosed than a rectangular shape. They also circulate air more efficiently than rectangular structures
The plants in this type of greenhouse will receive more direct sunlight throughout the day, which means more consistent heat input. A rectangular greenhouse will have less sun in the morning and evening, and the most at midday.
A dome receives consistent sun and heat throughout the day because the sun follows the shape of the dome. Your plants will appreciate this, and the added light and heat will be a benefit during the dark winter months.
Thirty to 40 per cent less surface area also means 30-40 per cent fewer materials used in construction. Geodesic dome greenhouses are relatively inexpensive to construct, depending on the design you use.
