Greenhouse and Tunnel Supplies
Whether you grow from earliest spring to late fall or run your production year-round, our season-extension supplies provide the versatility and durability you need to protect your crops from the elements. We offer row covers in a range of lengths and densities; benders and jigs for high tunnels and low tunnels; and supports, anchors, and hardware to keep it all together.
Use our calculators and construction manuals to plan ahead, estimate costs, and determine the right season-extension configuration, components, and quantities.
