High Tunnels & Cold Frames

Harvest more and extend your growing season by building your own high tunnel greenhouse (hoop building) or growing shelter using our high quality cold frames. We have many styles and configurations of high tunnels to choose from to help you enjoy increase your crop growth, as well as to extend your season. FarmTek cold frames and high tunnels greatly improve all of the vegetables that you grow, especially more delicate greens — exceed production with less space. Keep your growing environment ideal with fans, automatic shutters, pre-wired thermostats, and a vented heater inside your cold frame or high tunnel.
