USDA's EQIP program provides cost-share for eligible high tunnels. Rates and caps vary by state. We're not the policy experts (your local NRCS office is) but we know these structures, and we'll supply the spec sheets and documentation your application needs.
CT Greenhouse is not affiliated with USDA. Program rules, cost-share rates, and deadlines are set by NRCS and vary by state. Always confirm with your local office.
We're publishing these one state at a time so each one is accurate. Call an owner and we'll tell you what we know about your state's program and get your spec sheets started.
Phenomenal Experience! Access to knowledgeable people in today’s culture is huge, and not just ‘any people’ but Toby and Aaron are the owners!
Yes. Our structures are designed to meet NRCS Conservation Practice Standard 325, and we supply the documentation your EQIP application needs. We'll also point you to your state's program, though the rules themselves are set by NRCS, not us.
Eligibility and cost-share rates vary by state and practice standard. Choose your state in the NRCS section above for local requirements, and we'll help you match a structure to them.
Every Grower, Grower Plus, and Grower Pro is fully customizable: width, length, sidewall height, end walls, doors, and ventilation. We start from your farm and your crop plan.
Most kits ship ready to build. Smaller configurations like a 20 x 48 or 20 x 72 usually go up in 1 to 3 days with 2 or 3 people. Larger sizes like a 30 x 96 or 30 x 148 typically take 3 to 7 days with a crew of 3 or 4. We'll walk you through it by phone.
We're farmer-owned out of Portland, CT and Afton, MN, and we ship high tunnel kits nationwide, with free shipping in most of New England. Kits ship on a single pallet that slides off the trailer. Tell us where you are and we'll sort out freight.
Tell us a little about your operation and an owner will get back to you, with pricing for your configuration.
