Choosing between a high tunnel and a freestanding greenhouse can be tricky, especially when each option has its unique advantages. At Harnois Greenhouses, we aim to make that decision easier by breaking down the differences, uses, and benefits of these two structures so you can find the perfect fit for your growing needs.
What is the Difference Between a High Tunnel and a Freestanding Greenhouse?
High Tunnel Overview
A high tunnel is a simple, economical structure designed to protect crops and extend the growing season. It is typically made of a hoop frame covered with a single polyethylene film and relies on natural sunlight and ventilation. High tunnels are ideal for in-ground growing, but we are seeing more and more table growing for berries. We are not comparing a high tunnel and caterpillar greenhouses.

Freestanding Greenhouse Overview
A freestanding greenhouse is a sturdy structure with a gothic shaped frame and often features inflated double-poly or polycarbonate panels as its covering. Unlike high tunnels, freestanding greenhouses usually include climate control systems like heating, cooling, and artificial lighting, allowing for precise growing conditions year-round.
