Consulting and Greenhouse Supplies


After years of constructing other company's high tunnel kits on our own farms, we haven taken the best of what we've seen elsewhere and developed our own high tunnel frames and greenhouses. Our Connecticut Greenhouse Company frames are perfect for season extension, summer tomato production, propagation, or any other other use on the farm. We will work with you to customize the design to match the specific needs of your growing operation.

Our most popular structure is a 30' wide Gothic frame, but we can provide custom widths from 8' to 30' depending on your needs. High tunnels and greenhouses can be in any length up to 400' long.  All structures come standard with roll-up sides and metal end-wall construction.
