Greenhouses,  Tunnels and Caterpillars

Over the years, I have dealt with a number of companies that make quality greenhouses and tunnels. In our cold Canadian climate all of our shelters need to withstand snow loads

For bigger houses, I've worked with and totally appreciated Harnois. These guys might be the biggest greenhouse manufacturers in North America. Pricier perhaps, but top quality for sure. www.harnois.com

Four Season Tools, from Kansas is also a group I like. They custom built affordable and versatile season extension technologies. Being growers themselves, they also offer great service. Four Season Tools. www.fourseasontools.com

Finally, I really like the caterpillar tunnel design (and price!) from Farmer Friend LLC in Tennessee. . www.farmersfriendllc.com
