Whether you grow from earliest spring to late fall or produce year-round, our season-extension supplies can provide the versatility 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.
