High-tunnel greenhouses, also called hoop houses, are a popular choice for growers looking to extend their growing season and improve their crop yields. These commercial greenhouse structures offer an affordable and effective way to protect crops, boost production, and take control of your growing environment.
At Harnois Greenhouses, we specialize in durable, customizable high tunnels that meet the needs of growers across North America. In this blog, we’ll cover everything you need to know about high tunnels and why they might be the perfect fit for your growing operation.
What is a High-Tunnel Greenhouse?
A high-tunnel greenhouse is a structure designed to provide a controlled environment for growing crops. Unlike traditional greenhouses, high tunnels are usually unheated and rely on natural sunlight to maintain a warm climate. The design typically includes:
- A simple frame covered with durable polyethylene film.
- Roll-up or adjustable sides for ventilation.
- Flexible sizes to suit small farms or large-scale operations.
These structures are ideal for extending the growing season, starting plants earlier in the spring, and even growing year-round in mild climates.
Benefits of High-Tunnel Greenhouses
Boost Crop Yields
High tunnels create an optimal environment that can increase crop yields by up to 50%. The controlled conditions protect plants from extreme weather, pests, and diseases, ensuring healthier and more productive harvests.
Extend the Growing Season
With a high tunnel, you can start planting weeks earlier and continue harvesting long after the typical growing season ends. Some growers even use high tunnels for winter farming.
