We recommend setting the ground stakes in concrete like small fence posts. They are typically spaced every 4′ or 5′ depending on the kit. If concrete is not practical for your site, contact us and we’ll help you choose another anchoring method.

The hoops slide into galvanized steel ground anchors or stakes that are slightly wider than the hoop tubing. Once positioned, the stakes and hoops are drilled and bolted together to secure the frame.

Quonset greenhouses can be raised to as much as 12′ tall by using longer ground stakes. Gothic structures generally have a fixed height, although some customizations may be available for your project.

Manual roll-up sides are the most popular option because they are simple and effective. Powered exhaust fans with fresh-air intakes offer more controlled airflow while keeping the greenhouse more enclosed, but they require a power source. Some growers use both.

Ventilation is the most important addition for most growers. Shade cloth can reduce summer heat, and weed-barrier fabric helps keep the growing area clean. We can recommend the right combination for your location and crops.
