WHY 28' WIDE?
A wider greenhouse changes what's possible on your farm.
More row space. A 28' width accommodates four to five growing rows with generous working aisles between them — no more squeezing equipment through tight spaces.
Equipment-friendly. Wide enough to run a small tractor, walk-behind implements, or a cart down the center aisle without disrupting your crop rows on either side.
Better airflow and light distribution. The wider span means less shading from the structure itself, with more even light across your entire growing area.
Higher yield per structure. More square footage per kit means a lower cost-per-square-foot compared to running multiple narrower structures.

NRCS SECTION
NRCS Grant Ready
The 28' Pro Series is an excellent choice for farmers seeking grant reimbursement through the USDA's Environmental Quality Incentives Program (EQIP). Our NRCS style is designed to meet most high tunnel specifications — and our team has helped hundreds of farmers navigate the process successfully.
​
Because requirements vary by county, we recommend contacting us before ordering so we can confirm this kit is the right fit for your area. We know what specs matter and we build to meet them.

**Buyer must either pick up kit or make arrangements with the terminal within 1 day of being contacted from the terminal with notification that kit is ready. Not picking up kit within this time frame may result in late fees, storage fees, or ultimately return of kit to Greenhousekits1 at buyers’ expense. In this scenario, buyer will also be responsible for 20% re-stock fee and any damage occurred during travel back to Greenhousekits1.
​
Please check your kit upon arrival for all parts. We will send replacement/missing parts at no additional charge up to 2 months from kit pick up. After the two months following pick up, buyer is responsible to pay for any additional parts and shipping.
We offer a fourteen day money back refund upon return of a greenhouse kit in original, unopened condition. Because we custom build each kit as it is ordered, once an order is placed, the process begins immediately (parts are ordered and labor begins etc. for your kit). Due to this, all cancellations are subject to a 20% materials fee. Buyer pays return shipping.
