What type of greenhouse thrives in winter conditions?

If you live in an area with cold winters, you might be wondering what kind of greenhouse is best for growing plants during the colder months. Fortunately, the Deep Winter Greenhouse (DWG) was created for this exact purpose. Here are some key features of a DWG that make it an ideal choice for winter growing:

Passive Solar Design: DWGs rely solely on the sun’s energy to heat the greenhouse. The design includes large south-facing windows, a thick thermal mass wall, and insulation in the roof and north walls to retain heat.

Deep Insulated Beds: The beds where plants grow are located inside the thermal mass, which keeps them warm and protected from the cold. The soil in the beds can stay above freezing temperatures, even when it’s well below freezing outside.

Supplemental Lighting: In the darkest winter months, supplemental lighting can be added to provide extra light for plant growth.

Minimal Fossil Fuel Use: With its passive solar design and deep insulated beds, a DWG requires very little energy to keep it warm during the winter. This means that it is a much more sustainable and environmentally friendly option than traditional greenhouses that rely on fossil fuels for heat.

Durable Materials: The design of a DWG uses durable materials like concrete and polycarbonate panels, which can withstand the harsh winter weather.

Overall, if you’re looking for a greenhouse that can handle cold winters without the need for excessive fossil fuel use, a Deep Winter Greenhouse is an excellent choice. Not only will it allow you to continue growing crops throughout the colder months, but it’s also a great way to reduce your environmental impact.

The Benefits of Deep Winter Greenhouses

Deep Winter Greenhouses (DWGs) are becoming increasingly popular for gardeners and farmers looking to extend their growing season and reduce their carbon footprint. The benefits of DWGs include:

• A longer growing season: DWGs can extend the growing season by up to three months, making it possible to grow crops year-round.
• Reduced heating costs: The passive solar design of DWGs means that they require far less energy to heat than traditional greenhouses.
• A smaller carbon footprint: By reducing the amount of fossil fuels required to heat the greenhouse, DWGs help to reduce carbon emissions.
• Higher yields: DWGs provide a more stable growing environment which can lead to higher crop yields.

These benefits make DWGs an attractive option for gardeners and farmers who are looking to grow crops in colder climates while reducing their environmental impact.

Understanding Passive Solar Greenhouses

Passive solar greenhouses are designed to capture the energy of the sun and use it to heat the greenhouse. These greenhouses are built with a south-facing wall that is angled to collect the most amount of sunlight during the winter months. The wall is made of an insulated material that is designed to both retain heat and reflect it back into the greenhouse. The design of passive solar greenhouses allows them to maintain a temperature that is higher than the outdoor temperature during the winter months. This is achieved through the use of thermal mass, which absorbs and stores the heat from the sun during the day and releases it slowly at night.

How DWGs Reduce Fossil Fuel Consumption

DWGs reduce fossil fuel consumption by using passive solar heating, which eliminates the need for traditional heating sources such as propane or natural gas. The design of the greenhouse also includes insulation and thermal mass, which helps to retain and release heat. The reduced energy consumption of DWGs leads to a smaller carbon footprint and lower operating costs. In fact, the energy savings can be up to 90% compared to traditional greenhouses. This makes DWGs an attractive option for those looking to grow crops while minimizing their environmental impact.

Designing Your Own Deep Winter Greenhouse

Designing your own Deep Winter Greenhouse may seem like a daunting task, but it is definitely achievable. Here are some key steps to follow:

1. Consider the climate in your area and the crops you want to grow.
2. Choose a location that has good southern exposure and access to water and electricity.
3. Design the greenhouse with a south-facing wall, insulation, and thermal mass.
4. Install a ventilation system to control the temperature and humidity inside the greenhouse.
5. Choose the right materials for the walls, roof, and flooring.

Choosing the Right Location for a DWG

Choosing the right location for your DWG is crucial for its success. You want to choose a spot that receives ample sunlight and is protected from extreme winds. Here are some key factors to consider:

• Southern exposure: The south-facing wall of your greenhouse should receive maximum sunlight during the winter months.
• Soil quality: Choose a location with good quality soil, as this will help with drainage and provide nutrients for your crops.
• Access to water: Make sure you have access to water for your crops and for your heating system.
• Protection from wind: Choose a location that is protected from strong winds, as this can damage your greenhouse and impact the growth of your crops.

Plants that Grow Best in DWGs

DWGs are designed to grow crops during the winter months, so you want to choose plants that are well-suited to colder temperatures. Here are some plants that grow well in DWGs:

• Spinach
• Kale
• Collard greens
• Carrots
• Radishes
• Beets
• Lettuce
• Arugula
• Microgreens

These plants are well-suited to colder temperatures and can thrive in the stable environment provided by a DWG. By choosing the right plants, you can achieve a successful harvest even during the cold winter months. In conclusion, a DWG is an excellent option for gardeners and farmers looking to extend their growing season while reducing their environmental impact. By understanding the benefits of a DWG, the design process, and which plants to grow, you can successfully create your own passive solar greenhouse.
