We've built in them. We've grown in them.
Twenty years of combined experience building, renovating, and growing in these structures. Every design decision comes from a season in the field, not a catalog.

Designed around your farm
Widths, lengths, end walls, and ventilation matched to your crops, your weather, and your NRCS contract if you have one.

Fast, owner-friendly builds
A farmer's time is their most valuable asset. That's why our kits come with long, pre-drilled sections of American-made steel tubing, secured with heavy-duty hardware. With less to manage during the build, more of your time goes to farming.

Stocked for the season
We can ship a full line of commercial growing supplies with your structure to save you time and money.

Owners / Farmers / Operators
Built by Growers for Growers
CT Greenhouse started on a farm, with a side business bending greenhouse frames. With twenty years of combined experience building, renovating, and growing in these structures, Toby and Aaron still design every kit around how growers actually use it. And when you call, you reach someone who knows the product inside and out.
"Our mission is to be the go-to solution for growers of all sizes."
Growers keep our numbers.
"Literally the best greenhouse company out there. Durable structures, easily shipped and received, the two guys who run it are incredibly knowledgeable and always pick up."
"Phenomenal Experience! Access to knowledgeable people in today’s culture is huge, and not just ‘any people’ but Toby and Aaron are the owners!"
"Aaron was very knowledgeable and informative in helping us select which house would be best for our farm. We know this greenhouse will increase our productivity and extend our season for many years to come!"

Are CT Greenhouse high tunnels NRCS-eligible? add
Yes. Our high tunnels are designed to meet NRCS Conservation Practice Standard 325, and we supply the documentation your EQIP application needs.
Do you ship nationwide? add
Yes. We ship high tunnel kits, greenhouse kits, and supplies anywhere in the United States from our locations in Portland, Connecticut and Afton, Minnesota.
How much does a high tunnel cost? add
Kit pricing varies based on width, length, and features. Our team will provide quick, straightforward pricing. Contact us for your personalized custom quote.
Can I install a high tunnel kit myself? add
Yes. Our frames are designed for ease of installation. Many customers build their structure with a small crew, and we are available by phone for technical support throughout your build.
What makes your frames different? add
American-made steel tubing, a truss on every bow of our high tunnels, and a design shaped by years of building and growing in high tunnels ourselves. The result is a frame that is easier to build, stands up to farm weather, and keeps your plants happier.
