Water Catchment & Drip Irrigation Installations

We sell a variety of high tunnel water catchment & irrigation materials, design functional systems, and provide installation services. All of our installations and materials meet NRCS standards. We can also consult on and install small-scale field irrigation systems.

Growing Supplies Catalog

Our Growing Supplies Catalog offers a wide range of high-quality and organic growing supplies, including materials for pest & weed management, seed starting, irrigation, trellising, fertilizing, season extension, and more.

The History of Our Social Enterprise

In 2011 – 2012, Grow Appalachia began developing and installing scale-appropriate high tunnels in central Appalachia to help families grow food year-round using our own funding. Over the next couple of years, we learned about the resources available through the Natural Resources Conservation Service (NRCS), and NRCS learned about Grow Appalachia. This partnership provided a new pathway for growers in the region to access financial resources that support the installation of a high tunnel on their farm.

Due to continued demand and the new source of funding, Grow Appalachia established the Social Enterprise program. The Social Enterprise program focused primarily on high tunnels during these early years, because there weren’t many companies selling high tunnel kits, and high tunnel installation crews were non-existent. Grow Appalachia filled that gap in access for the region.

As of 2025 Grow Appalachia has manufactured and installed over 180 high tunnels. With great effort and reservation, at the end of 2025 we decided to cease manufacturing and installing high tunnels as part of the Social Enterprise. We see that the gaps we noticed in the early years have been filled by other high tunnel installation crews. We do not see our role as being a competitor in this work but rather as an educator.

The Social Enterprise staff will continue supporting high tunnel producers through technical support and consultations. The Social Enterprise will continue providing high quality organic fertilizers, growing supplies, and contracted services, including high tunnel rainwater collection systems, drip irrigation support, winterization, and other associated high tunnel practices. On this page, you can order growing supplies or submit a high tunnel service request.

We thank all of the farmers, growers, organizations, agencies, and businesses that have contributed to this experience. We have worked side by side with so many over the years, and we will continue to do so.

Additional High Tunnel Components

30% Shade Cloth

  • Protects crops from summertime heat & sun exposure, which can negatively impact fruit production on crops like tomatoes and lead to early bolting
  • 30% shade cloth (which allows 70% light transmission) is the most common shade cloth percentage for vegetable production
  • Can be attached with wiggle wire along the hip boards OR using shade cloth clip-its and rope attached to eye bolts along the baseboards (see our Growing Supplies catalog)
inflation blower

Inflation Blower / Second Layer of Plastic

  • Operation of the inflation blower requires electricity
  • The inflation blower adds an insulative layer by creating a layer of air in between two layers of greenhouse plastic
  • Requires the installation of a second layer of greenhouse plastic

Frequently Asked Questions

A high tunnel is a season extension tool that facilitates year-round crop production. High tunnels allow producers to manage their growing environment (temperature, irrigation, and light), mitigate weather extremes, and grow high-quality produce more consistently.

A covered high tunnel creates a dry environment requiring irrigation. Water can be collected from your high tunnel ‘roof’, stored in catchment tanks and used for drip irrigation.

  • Reduces diseases caused from moisture residue on crops
  • Reduces erosion by slowly delivering water directly to the root zone
  • Efficiently irrigates your crops
  • Improves your time management
  • Reusable, durable materials can be used over several seasons
  • Soft water reduces salt build up
  • Reduces soil erosion around as well as inside the high tunnel
  • Decreases reliance on outside water sources that can lead to nutrient build up
  • Saves on water supply expenses on the farm
  • Reduces carbon footprint
  • For example, our 15’ x 48’ gothic high tunnel can collect 500 gallons from a single 1/2″ rain
  • Underground (24”) trench and attachment to water catchment tanks
  • 2″ PVC line from tanks to the sand pump and filter inside the high tunnel
  • Intexx Sandfilter pump (2.4amp), silicone sand, ¾”pressure reducer (15psi), 3/4” in-line check valve
    • Replacement parts can be purchased here
  • 2”Mainline layflat (header line) with end cap, gaskets and hose clamps
  • ½” AQ-15mil Premium drip tape with 12″ emitter spacing (enough for 12 rows*)
  • 12 Tapeloc swing valves
  • 12 Tapeloc end plugs
  • Extra Tapeloc couplings for repairs
  • Goof plugs to repair or plug holes in layflat
  • 8″ sod staples to hold drip irrigation lines in place

*you may select a different number of rows of drip irrigation

  • Vinyl gutters with connectors, hanger brackets, and end caps
  • 6”-12” poly plastic patch tape for flow from plastic to gutter (UV stable)
  • Overflow runoff materials and installation (10’ away from tunnel off of 2 tanks)
  • Gutter to tank connection with down spouts and removable mesh basket
  • (3) 550 gal. black water catchment tanks with 3 ball valves
