The Social Enterprise emerged in 2014 after determining the need for smaller high tunnel designs and organic growing supplies for our small-scale farmers. From 2014 to 2025, Grow Appalachia’s Social Enterprise manufactured and installed 182 high tunnels in the region, primarily in Kentucky.

Starting in fall 2025, after carefully assessing needs of farmers and services provided by regional high tunnel builders, the Social Enterprise decided to close the chapter on full high tunnel builds and pivot to focusing on high tunnel repair, maintenance, irrigation, and water catchment systems. We continue to sell high quality, organic growing supplies, and you can still place an order through our online catalog.

High Tunnel Services

A high tunnel is a season extension tool that facilitates the production of fresh vegetables twelve months a year. The benefit comes from the ability to manage the growing environment – temperature, irrigation, light (to some extent) and weather extremes. This element of control provides an opportunity to grow quality vegetables in a more consistent and planned manner.

We offer the following services related to high tunnel systems: repairs (e.g. replacing components), replacing plastic, adding new components (e.g. shade cloth, inflation blower), consultation & education (e.g. site selection, year-round maintenance), and water catchment and drip irrigation systems. We no longer offer full high tunnel builds from start to finish.

End Wall Upgrade Options for Gothic High Tunnels

Your needs as a grower may have evolved since you first purchased your high tunnel. For small (15-16′ wide) gothic high tunnels, we can replace and upgrade end walls to meet your current needs. Options include our basic wooden end walls, an equipment door end wall, and a more robust galvanized steel end wall.

High Tunnel Water Catchment & Drip Irrigation Systems

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 irrigation. Recycling collected water through an irrigation system requires catchment tanks, a filter, a pump to pressurize the water (electric hook up necessary), a pressure reducer to stabilize pressure, a check valve for backflow prevention, a header line, and drip tape with ‘drip’ emitters.

We sell a variety of water catchment & irrigation materials, design functional systems, and provide installation services. All of our installations and materials meet NRCS standards.

  • 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
