NRCS EQIP Eligible · DIY or Installed
Most NRCS-funded poly-film tunnels don't make it past five years. CatchSunlight builds with 6mm 4-layer polycarbonate — engineered to survive the winters that end cheap structures in season two.

Whether you have help lined up or want Russ's crew to handle the build, the structure is the same — engineered for decades of use, EQIP-compliant by design.
A complete materials package — every panel, fastener, hoop, and trim piece needed to build the tunnel yourself.

The most common high-tunnel grant recipient is a poly-film structure — inexpensive up front, funded by EQIP, and replaced in five years. Half of funded poly-film tunnels don't survive past year five in windy areas. Polycarbonate is a different product category.
Some NRCS field offices have incorrectly believed that only poly-film structures qualify for the high-tunnel grant. Polycarbonate is explicitly eligible under NRCS EQIP Practice Code 325. For application and eligibility questions, contact your local NRCS/USDA Service Center. See the grants page for the full breakdown.

Drawings & Layout
These drawings show how the greenhouse goes together: the post pattern in the ground, the hoop and truss profile, both endwalls, and the full drawing set on one sheet. Click any drawing to open it full size and read the dimensions.
Standard configuration is 27' wide × 38' long (~1,000 sq ft). Posts sit in two rows 25'–28.5' apart, with hoops typically 45.5" on center. Spacing is adjustable from 45" to 80" — opening it up gives you more tunnel length from the same number of hoops at minimal extra cost, a real value-add most kit suppliers don't mention.
Call to discuss your site dimensions — Russ will spec the configuration that makes sense for your layout and budget.
