Season Extension Supplies

Whether you are growing from earliest spring to late fall or in year-round production, our line of versatile season-extension supplies can provide the components 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 of assorted design; and supports, anchors, accessories, and hardware to put and keep it all together.

We also provide a set of calculators and construction manuals to help you plan ahead, estimate costs, and determine the right season-extension configuration, materials, and quantities.

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