Hoop House Tunnel Greenhouse Agricultural Single-Span Greenhouses Accessories Galvanized Steel Pipes High tunnels are a great and simple way to increase your crop yield. Most importantly, they extend the growing season. By protecting plants from the elements and providing insulation, the ground takes much longer to freeze inside a high tunnel and frost damage is reduced for an extra 3 to 4 weeks on each end of your growing season. This allows growers to start planting earlier
