Description

The 8 x 22 Palram Canopia Natura Cedar Greenhouse provides a generous 176 square feet of space, perfect for serious gardeners who want to grow all year round. Its natural cedar frame and crystal-clear polycarbonate panels offer durability and an ideal environment for plants. The cedar resists pests and decay, while the panels allow over 90% light transmission without exposing plants to harmful UV rays.  

Designed for versatility, this spacious greenhouse accommodates a variety of plants and growing techniques. Four automatic roof vents adjust to temperature changes, maintaining airflow and preventing overheating. A wide, lockable door with a low-threshold ramp makes bringing in wheelbarrows and gardening tools easy. Built-in gutters allow for rainwater collection, helping with sustainable irrigation.  

Built to withstand the elements, this greenhouse withstands winds up to 62 mph and supports snow loads of 16 lbs/ft². Despite its size, assembly is straightforward, with pre-cut panels and pre-drilled profiles. Plenty of space for shelving, storage, and propagation areas gives you the flexibility to organise it however you like.  

This model combines craftsmanship with practicality, and its design is based on over 60 years of greenhouse expertise. A five-year warranty provides extra peace of mind, ensuring a reliable, long-lasting growing space.

About Cedar

Cedar is an excellent choice for greenhouses due to its natural durability and resistance to the elements. Rich in natural oils, cedar is naturally rot-resistant, helping prevent decay, insect damage, and mould growth without chemical treatments. Its weather-resistant properties make it well-suited for outdoor structures, easily standing up to rain, humidity, and temperature fluctuations. Additionally, cedar is dimensionally stable, meaning it resists warping and cracking better than many other types of wood. Beyond its practical benefits, cedar has a pleasant, aromatic scent and a timeless aesthetic, making it a beautiful and long-lasting option for greenhouse construction. Applying a protective finish can extend its lifespan and maintain its rich appearance, ensuring years of reliable use.

Make the Most of Your Wooden Greenhouse:

The expanded dimensions of the 8 x 22 Palram Canopia Natura Cedar Greenhouse provide endless possibilities for an efficient and well-organised growing space. With 22 feet of length to work with, you can design distinct zones for different stages of plant growth, creating a natural flow from propagation to mature plants. The generous height supports vertical gardening, making it easy to hang baskets (not included) from the sturdy cedar frame or install adjustable shelving (not included) along the walls to significantly increase planting capacity.  

A wide interior allows for a central walkway and easy access to every part of the greenhouse. A potting station (not included) near the entrance keeps your workspace separate from your growing areas. The extended length also makes it ideal for microclimate zones. Position heat-loving plants toward the sunniest end while keeping more delicate varieties in the cooler section.  

For climate control in a greenhouse of this size, consider a multi-zone automated watering system (not included) and strategically placed fans (not included) to maintain proper air circulation. The four automatic roof vents already help regulate temperature, but installing shade cloth can provide additional heat management during peak summer months.  

Well-defined pathways along the 22-foot span will help prevent soil compaction and keep everything easily accessible. Incorporating thermal mass elements like water barrels or stone flooring can stabilise temperatures without taking up valuable growing space. With a thoughtful layout, this spacious greenhouse provides the flexibility and efficiency needed for year-round growing success.

Wooden Greenhouse Aftercare:

Natural Aging Option - Cedar can be left untreated, allowing it to naturally weather to an elegant silvery-grey patina through exposure to sun and rain. This aging process doesn't compromise the wood's structural strength; many find the weathered appearance aesthetically pleasing.

Protective Treatment Options - If you prefer to maintain cedar's original colour and maximise its lifespan, consider these protective finishes:

• UV-Protective Stain or Sealant - Shields the wood from sunlight to prevent fading and greying while offering weather protection.
• Exterior Wood Oil - Natural options like tung or linseed oil penetrate the wood, highlighting its grain pattern while providing water resistance.
• Wood Sealer -  Clear or semi-transparent sealers create a protective barrier against moisture while maintaining wood breathability.

Treatment Guidelines for Cedar

When treating cedar in a greenhouse environment, follow these key principles:

Choose breathable, non-toxic finishes to avoid introducing harmful chemicals into your growing space. Plan to reapply your chosen treatment every 2-3 years as needed. Ensure proper ventilation around wooden elements to prevent moisture accumulation.

Interior Treatment Considerations

For cedar surfaces inside the greenhouse, prioritise plant-safe options:

- Eco-friendly, non-toxic sealers
- Natural wood oils
- Beeswax-based treatments

These choices protect the wood while maintaining a healthy environment for your plants.
