Overview

As your gardening grows, your greenhouse can grow with it. This kit adds 4 ft of length to a MONT greenhouse. Please note it is not a greenhouse on its own; it attaches to the MONT you already have.

It's built from the same materials as the greenhouse: high impact, UV stable 8 mm twin-wall polycarbonate on a heavy-duty extruded aluminum frame, with an integrated flush base and dual rain gutters. Every extension includes its own 2 ft x 2 ft roof vent with an automatic opener, and the whole kit is made in the USA from start to finish.

Our tip: Order the frame color that matches your existing greenhouse. If you have the work bench, shade or watering system, the Premium package adds matching sections for the new space.
