30’ Gothic Hoophouse

Nifty Hoops’ flagship structure, these 30’ wide gothic high tunnels can be built from 24’ to 192’ long. They provide the strength to withstand northern winters and the features to make growing in them a pleasure.

Installation Options:

  • Starter Build — Our lead builder will start your install with you and set up the build for you to complete, or direct your workforce in installing the hoop. We bring specialized tools to pound and laser-level your groundposts and get your project off the ground. We also support you with detailed videos of each step of the build.

  • Community Build — We’ll work with your CSA membership, neighbors and friends in an old-style barn raising type event.

  • Full Installation — We can build your hoophouse for you. We usually finish these in one day!


  • Strong - Triple gusseted cross-braces span every interior bow and stretch 22’ across the 30’ structure. While creating a strong house for our northern climates, these braces also integrate with our overhead irrigation and plant trellising system, creating a quick and easy way to train tomatoes, cucumbers and other vining crops.

  • Rugged - Our Gatorshield galvanized tubing and strong woven poly end-wall and rollup panels are built to last.

  • Grower-friendly - The 6’ side-wall height provides complete perimeter walk area and easy access to the complete growing footprint.

  • Accessible - Our end-wall design incorporates a hinged door for daily and entry and two large equipment access panels that give you cost effective and easily-winterized doorways.

  • Automated louver ventilation - we have incorporated our low-voltage/low-energy-use louver motors as standard equipment on our hoophouse installations. Say goodbye to industry standard louver motors that use power to stay open, hour after hour, day after day. We are the first to market with a low-voltage louver system that uses only pennies per year, standard on every hoophouse.

  • Many other features, including double layer poly with low-voltage/low-energy-use inflation blower and roll-up sides with baffled ends.

Solar power

Complete 200W / 12V solar package: Upgrade the standard build to include (2) 100W 12V solar panels with (2) deep cycle batteries and charge controller/battery management. The 200W charging capacity of this system keeps you powered through long winter nights. The system powers, and includes, low voltage louver motors and low energy use inflation blower system. Fully installed. Can also power the automated side ventilation upgrade listed above

Note: While this solar package is generally more than capable of powering our low voltage/low energy hoophouse components, there is no guarantee that it will meet your total energy needs throughout the year. Local weather and site conditions, shading from buildings or trees, and your actual energy use will determine if additional panels and/or batteries are required.
