Oregon's unique climate makes it a hotspot for greenhouse farming, from the rainy Willamette Valley to the drier high desert regions.
If you're considering investing in a custom commercial greenhouse, careful planning can set you up for long-term success. Here are expert tips for you to design the right greenhouse with your commercial greenhouse builder.

1. Choose the Right Location
In Oregon, location is key to greenhouse success. Look for a site with excellent sunlight exposure, as even the cloudier regions get significant light during peak growing seasons. Flat, well-drained land is ideal to minimize foundation costs and avoid flooding in Oregon’s wetter regions and seasons. Additionally, proximity to utilities—like water, electricity, and natural gas—can significantly reduce installation and operational expenses.
For businesses in urban hubs like Portland or Eugene, zoning laws may limit your options. Be sure to research local regulations and obtain permits early in the process. If you're in Eastern Oregon, take advantage of the increased sun exposure by designing for year-round production.
2. Select the Right Materials
Choosing the right materials for your greenhouse frame and covering ensures durability and efficiency. Oregon’s weather varies significantly, so tailor your materials to withstand the local conditions.
Areas to Consider
Frame: Aluminum is lightweight and corrosion-resistant, ideal for wet climates like the Oregon Coast. Steel is sturdier and better for areas prone to high winds or snow, such as Central or Eastern Oregon.
Covering: Polycarbonate panels strike a great balance between durability and insulation. They’re perfect for handling Oregon’s mix of rain, sun, and occasional frost. For larger-scale operations, poly film may be a cost-effective option, but one should also consider glass, which offers superior light transmission, but at a higher cost.

3. Optimize Greenhouse Size and Layout
A common mistake for first-time greenhouse builders is underestimating the required size. Calculate the space you need for current production and leave room for expansion as your business grows. Think about workflow efficiency—position aisles, benches, and equipment to allow easy movement for workers and machinery.
In Oregon’s climate, spacing between plants is critical to prevent fungal diseases, which thrive in humid environments. Incorporating adequate ventilation and dehumidifiers into your layout will help combat this.
4. Invest in Advanced Environmental Controls
Oregon’s varied climate requires a dynamic approach to heating, cooling, and irrigation.
Heating: If you are planning to grow year-round, invest in efficient heating systems like radiant floor heating or table heating systems for regions with chilly winters, especially in high-altitude areas.
Cooling and Ventilation: In warmer months, roll-up sides or automated ventilation systems can help prevent overheating, which is crucial for crops like tomatoes and leafy greens.
Irrigation: Drip irrigation systems are water-efficient and can be customized for various crop types. This is particularly beneficial in drought-prone regions like Southern Oregon.

5. Consider Long-Term Sustainability
Oregon businesses are increasingly prioritizing sustainability in their new constructions. A few ways to do this may be to incorporate solar panels or rainwater collection systems to reduce your environmental footprint and lower energy costs. Using local, sustainable materials can also enhance your brand’s reputation in eco-conscious markets.
