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.

Use our calculators and construction manuals to plan ahead, estimate costs, and determine the right season-extension configuration, components, and quantities.

Johnnys is committed to your success and is with you every step of the way.
