Which Kind Of Greenhouse Ought To Be Constructed?

When choosing a greenhouse, consider your gardening goals, space, budget, and plant types. Typical sizes range from compact 4-8ft hobby greenhouses to large 12-30ft commercial models. Height is also crucial, as taller 10-14ft greenhouses allow better air circulation. Larger greenhouses offer more growing capacity but require higher initial investment and maintenance.

Glass greenhouses have been around since the 18th century when travelers brought back exotic plants to overwinter in cooler, European climates. Window-mounted greenhouses are small lean-in structures that allow you to grow vegetables and herbs. Building a greenhouse requires careful consideration of materials and tools to ensure a sturdy and functional structure.

Toughened glass is more expensive but a better option in high-traffic areas or for kids. Aluminium is usually the material of choice for a glasshouse, either in natural metal or with a painted finish. A colored frame may fit into the garden better. Opt for greenhouse panels that are translucent or clear, such as clear plastic like polyethylene (PE), PVC, or other readily available materials.

There are various greenhouse materials, including glass, acrylic, and soil base and concreted leg posts. Glass greenhouses cost more initially but hold up better over time. For smaller-sized conservatories, a greenhouse with a soil base and concreted leg posts is the most cost-effective option.

What is the most popular type of greenhouse?

Traditional greenhouses, such as gable roof greenhouses, provide maximum sunlight and a large area for growing plants. They are simple to build and require more effort than other greenhouse types, but can be reasonably priced depending on the materials used. The side walls that receive wind are wider and flatter, but the structure’s skeleton makes it more durable.

A-frame greenhouses are simpler but equally popular, requiring fewer materials and being cheaper and easier to build. They are more difficult to maneuver indoors due to their wide base and narrow apex, and airflow may not be ideal at low edges and tight corners.

Are small greenhouses worth it?

Small greenhouses are ideal for those lacking outdoor space and need extra room to house plants. They effectively keep plants sheltered from the elements at any time of the year. The best small greenhouse depends on the space and number of plants to grow. Design is also important, with both traditional and stylish options available. Patio Glasshouses are small, durable greenhouses that prevent plants from freezing during winter and well-ventilated during summer. They are suitable for any garden size and are recommended for first-time greenhouse growers.

Why are greenhouses a problem?

Traditional greenhouses, powered by non-renewable energy sources, significantly contribute to CO2 emissions, with conventional greenhouses emitting around 575kg of CO2 per ton of lettuce. Advanced greenhouses, using renewable energy and closed-loop water systems, emit 352kg of CO2 per ton. This highlights the need for technological and methodological advancements to reduce greenhouse environmental impact. Additionally, greenhouses require significant energy to maintain optimal growing conditions, often sourced from fossil fuels, resulting in carbon emissions.

Is a green or clear greenhouse better?

Modern greenhouses have improved by using transparent materials, with clearer plastics being preferred for better photosynthesis. The goal is not to maximize sunlight, but to find the right balance between thickness and transparency. Some plants need enough sunlight to survive, while others need as much as possible, depending on the type of vegetation.

Weight is another important factor to consider when choosing a greenhouse covering. Thin plastic sheets are strong but can become heavier with added thickness, affecting the greenhouse’s frame. While heavy plastic is not bad, it’s crucial to ensure the frame is sturdy enough to support it. The right balance between thickness and transparency is essential for a greenhouse’s optimal performance.

What is the best shape for a greenhouse?

Freestanding greenhouses are versatile and can be placed anywhere in your garden, with an apex roof that allows light to enter from all four sides. Lean-to greenhouses take up less space but may receive less sun. Octagonal greenhouses are stylish and take up more room but provide a larger growing area. The best greenhouse material is aluminium or wood. Aluminium-framed greenhouses are lightweight, strong, and have a fine structure that allows more light and casts less shadow.

They come in various colors and require little maintenance. However, metal is a poor insulator, conducting heat away from plants inside. Wooden frames are strong, attractive, and bring a natural look to your garden, but require regular maintenance.

What is the most efficient type of greenhouse?

Twin-wall polycarbonate covers are more resistant to temperature variability and last more than double as long as poly film. However, greenhouses lose a lot of heat during winter months, especially at night. To improve heat retention, use winter-ready poly film glazing, which is heavier and more opaque, which attracts heat during the day and reflects it back into the greenhouse at night. Another option is installing a water wall for passive solar heat, which uses polyethylene bags filled with water to absorb solar energy during the day and radiate it into the greenhouse at night.

Are there any disadvantages to a greenhouse?

Weather conditions significantly impact agricultural production, with extreme weather events and climate disasters causing significant losses for farmers. Floods and droughts are the most immediate impactful weather events, while rising temperature extremes between 1991 and 2017 increased farm insurance loss payouts by $27 billion. Wet and cool springs can prevent farmers from planting crops, negatively affect early plant growth, and stress young plants, leaving them susceptible to disease outbreaks and pest predation.

Overly hot temperatures during the growing season can severely affect crop growth. Livestock production is also affected by extreme weather events, with drought being particularly tough on the cattle industry.

Greenhouse farming offers a significant advantage in controlling the greenhouse environment and greenhouse temperatures to support the growth of high-quality crops year-round. However, global warming caused by increasing greenhouse gases is contributing to more frequent and extreme unfavorable weather events and threatening global food security. The United Nations reports that the planet is averaging 1. 1 degrees Celsius above pre-industrial temperatures, which changes traditional weather patterns, causing more catastrophic heat waves, extreme precipitation events, and other weather-induced events.

Agricultural production and farm practices contribute to the climate change problem, releasing carbon dioxide and other potent greenhouse gases like nitrous oxide and methane into the atmosphere. About one-third to one-quarter of the planet’s annual greenhouse gases are contributed to the food supply chain. Consumers and food supply companies are demanding a more sustainable food supply chain supporting healthy environments and ecosystems.

Greenhouse farming is seen as one solution to the climate change problem, as it can mitigate high and low temperatures while growing food in regions where food production wasn’t previously possible. This reduces carbon emissions due to transportation, lessens the impact of supply chain shocks, and conserves water and nutrient use compared to traditional agricultural production. Growers can produce a larger volume of food in a smaller greenhouse space than outdoor production models, reducing the pressures to convert forests and prairies into farmland and maintaining ecosystems as critical carbon sinks.

Greenhouse farming involves various types of structures, depending on the goals and needs of the farming operations. Simple greenhouse structures can be built at a relatively small expense, helping small farmers and smallholder farms in developing nations extend their season and produce more food. High-tech controlled greenhouse structures replicated and managed at scale across multiple locations using farm management software can cost millions of dollars to build and are typically installed with high-tech management systems, including heat and humidity control, lighting, drip irrigation and fertigation, misting systems, and automated benching systems for moving potted plants.

Hoop houses and poly tunnels are greenhouses built on a hoop frame, made of materials such as bamboo, PVC pipe, or metal piping. They are relatively inexpensive to build and can be erected as temporary, seasonal structures or even designed to be portable. Many hoop houses are popular for lower budgets and simpler management goals. However, they can be adapted with high-tech innovations, such as complex HVAC, irrigation, and nutrient management systems, to meet commercial enterprise needs.

Polycarbonate and glass houses are more expensive to install but longer-lasting than plastic-covered hoop houses and are more commonly seen in commercial greenhouse house enterprises. Frame configurations for polycarbonate or glass houses come in many forms, including gable, flat arch, and gothic styles.

Shade structures and screen houses are used to cool temperatures and limit the sunlight a crop receives. Shade structures are beneficial for fast-growing greens, such as lettuce or baby salad greens, susceptible to sweltering weather. They are covered with a woven material that blocks sunlight and can be built over hoop frames or frames with more angular edges.

Greenhouse farming has pros and cons, such as mitigating extreme weather conditions, extending seasonality of crop production, higher-yielding crops, easier pest management, support for growing high-value crops and hard-to-find plant species, reducing water consumption, pesticide, and fertilizer use, and maximum profit in a small space.

To build, maintain, and run a profitable greenhouse farming business, it is crucial to consider your business goals and all the potential elements involved.

What is the ideal greenhouse?

Greenhouses come in various widths and lengths, with a minimum width of 6ft (1. 8m) for room for movement and 8ft (2. 4m) for staging. The eaves should be at least 5ft (1. 5m) tall for light. The biggest greenhouse is preferred, as most gardeners wish for one. There are three main greenhouse shapes: traditional, lean-to, and round, with newer shapes like domes also available. Traditional greenhouses use existing walls to hold heat, while lean-tos use bricks to hold sun heat, making them ideal for growing. Round greenhouses are useful for awkward spaces.

Does the shape of a greenhouse matter?

Greenhouses can be freestanding or attached, depending on whether they are located in the yard or attached to a home or other building. Freestanding greenhouses come in various shapes, such as gable roofs and Quonsets, and can be customized to hold heat and shed snow and rainwater. Attached greenhouses have a flat side and can be lean-to or even-span. They have a shared wall that provides heat during colder periods, but hot summer temperatures can add heat to the greenhouse.

Greenhouses can be simple or elaborate, depending on your budget and space. Shelf and cabinet greenhouses offer an ultra-compact but protected vertical environment for patio growing, while small, ready-made greenhouses can be purchased online and require basic assembly. A hoop house, a Quonset greenhouse made of steel or PVC hoops with plastic stretched across, is an inexpensive and easy-to-build option, costing $200 to $500. These greenhouses can be purchased and assembled or constructed from plans.
