Plantation Greenhouse Calgary

Plantation Greenhouse Calgary: Your Guide to Indoor Gardening in Alberta

Calgary's unique climate presents challenges for outdoor gardening enthusiasts. Short growing seasons and unpredictable weather patterns can make cultivating desired plants difficult. Plantation greenhouses offer a solution, extending the growing season and providing a controlled environment for thriving plants year-round. This article explores the benefits, considerations, and options available for setting up a plantation greenhouse in Calgary.

Benefits of a Plantation Greenhouse in Calgary

A plantation greenhouse offers several advantages for Calgary gardeners:

Extended Growing Season: Greenhouses create a microclimate, allowing gardeners to start plants earlier in the spring and extend the harvest into the late fall or even winter.
Protection from Harsh Weather: Calgary's weather can be unpredictable, with hail, strong winds, and temperature fluctuations. Greenhouses protect plants from these elements.
Pest and Disease Control: A controlled environment makes it easier to manage pests and diseases, leading to healthier plants and higher yields.
Optimal Growing Conditions: Greenhouses allow gardeners to regulate temperature, humidity, and light levels, creating ideal conditions for various plant species.
Increased Food Security: Growing food in a greenhouse contributes to local food security and reduces reliance on external sources.

Types of Plantation Greenhouses

Various types of greenhouses cater to different needs and budgets:

Hoop Houses: These are simple, cost-effective structures typically made with PVC pipes and covered with polyethylene film. They are suitable for season extension and protecting plants from light frosts.
Geodesic Domes: These dome-shaped greenhouses offer excellent wind resistance and even light distribution. They are often used for specialized growing or as attractive garden features.
Gothic Arch Greenhouses: The pointed arch design of these greenhouses maximizes interior space and allows for efficient snow shedding. They are a good choice for regions with heavy snowfall.
Rigid Frame Greenhouses: These sturdy structures, often made of aluminum or galvanized steel, are built to withstand Calgary's harsh winters. They offer excellent insulation and durability.

Choosing the Right Greenhouse Covering

The greenhouse covering plays a crucial role in regulating light, temperature, and humidity:

Polyethylene Film: This is a common, affordable option that provides good light transmission. Different thicknesses and UV stabilizers are available to suit specific needs.
Polycarbonate Panels: These rigid panels offer superior insulation and durability compared to polyethylene film. They are more expensive but have a longer lifespan.
Glass: Glass provides the best light transmission and offers a classic aesthetic. However, it is the most expensive option and can be prone to breakage.

Heating and Ventilation

Maintaining optimal temperature and airflow within the greenhouse is essential for plant growth:

Heating Systems: Options include electric heaters, gas heaters, and wood-burning stoves. Choosing the right heating system depends on the size of the greenhouse and the desired temperature range.
Ventilation: Proper ventilation helps regulate temperature, humidity, and prevent the buildup of pests and diseases. Roof vents, side vents, and fans can be used to achieve adequate airflow.

Lighting Considerations for Calgary Greenhouses

Calgary's winters have shorter daylight hours, which can impact plant growth. Supplemental lighting may be necessary:

LED Grow Lights: These energy-efficient lights provide specific light wavelengths that promote plant growth. They are a popular choice for supplemental lighting in greenhouses.
High-Intensity Discharge (HID) Lights: These powerful lights are effective for larger greenhouses but consume more energy than LEDs.
Fluorescent Grow Lights: These are a budget-friendly option for supplemental lighting, but they are less efficient than LEDs or HIDs.

Watering and Irrigation Systems

Efficient watering is crucial for maintaining optimal plant health:

Drip Irrigation: This system delivers water directly to the plant roots, minimizing water waste and preventing fungal diseases.
Soaker Hoses: These porous hoses slowly release water, providing deep watering for plant roots.
Overhead Sprinklers: While convenient, overhead sprinklers can increase humidity levels, potentially leading to fungal issues.

Site Preparation and Building Permits

Before building a greenhouse, consider the following:

Location: Choose a sunny location with good drainage and protection from strong winds.
Foundation: A level foundation is essential for stability. Options include concrete slabs, gravel beds, or wood frames.
Building Permits: Check with the City of Calgary for building permit requirements before constructing a greenhouse.
