Gutter Connected Greenhouses

Our gutter-connected (multi-span) greenhouses are most often engineered for large-scale commercial production. By joining multiple bays under a shared roof, these structures maximize grow area while minimizing land use. They support advanced climate control systems, facilitate efficient workflow, and are designed for straightforward initial construction and modular expansion.

What is a Gutter Connected Greenhouse?

Gutter-connected greenhouses are an ideal solution for large-scale commercial greenhouse growers requiring uninterrupted growing space. These modular structures are designed for scalability, with individual bays joined through shared gutters to create a continuous, integrated environment. Partition walls are an option to create smaller or individualized growing environments.

HighYield™ Kit or Gutter Connected Greenhouse?

In certain scenarios, a gutter-connected system may offer advantages over a HighYield™ Kit, particularly when:

  • Operating in warmer climates where high insulation is unnecessary
  • Working within spatial constraints that require efficient land use
  • Cultivating on a large scale (typically over one acre)
  • Planning for future expansion of the growing area
  • Roof venting allows for more efficient operations (passive venting)

Customized Business Solutions for the Commercial Greenhouse Grower

If a gutter-connected greenhouse is determined to be the optimal solution, we offer a range of integrated upgrades to enhance system performance and adaptability, including:

  • Wet wall evaporative cooling
  • High-pressure fogging systems
  • Automated roof venting
  • Polycarbonate or ETFE roofing options
  • SunSense™ environmental control system
  • LED supplemental lighting
  • Enclosed connecting corridors for seamless facility flow
  • Headhouse structure and layout

 

These systems can be incorporated into a new standalone structure or added to an existing greenhouse to support phased expansion—ensuring flexibility as your operation grows.

Gutter Connected Greenhouses: Cost-Effective Design Built Around Your Needs

While commercial gutter-connected greenhouses can be a more cost-effective option for certain growers, Ceres works closely with each client to determine the most suitable structure based on their specific application, site conditions, and long-term goals. We evaluate both upfront material costs and ongoing operational expenses to ensure the selected greenhouse system delivers optimal performance and value over time.

Gutter Connected Greenhouse Kits FAQs

A gutter-connected greenhouse consists of multiple center-gable structures joined together at their low eaves by a shared gutter.

Yes, they can be. Gutter-connected greenhouses are particularly well suited for large-scale commercial operations because they make efficient use of available land. Additionally, due to the large square footage and overall volume of these facilities, the lower insulation value of the exterior walls has less impact on overall energy efficiency compared to smaller greenhouses

Crop type is less of a determining factor than scale when it comes to gutter-connected greenhouses, as these structures are designed primarily to support large-scale growing operations. With proper environmental controls and layout, virtually any crop can be well suited for this type of greenhouse.

Yes, provided the performance and operating requirements of the facility are understood from the outset. In colder winter climates, heating costs can be significant depending on temperature setpoints; however, due to the large overall volume of gutter-connected greenhouses, the lower insulation value of the glazing has a reduced impact on overall energy efficiency.

Gutter-connected greenhouses generally become more energy efficient as their overall size increases. Most are glazed with 8 mm polycarbonate, so a relatively small configuration—such as two 30′ × 100′ greenhouses combined into a 60′ × 100′ structure—would not be particularly energy efficient. However, these facilities do offer roof venting, which provides a passive and energy-efficient method of cooling during the summer months. As the scale increases to an acre (approximately 45,000 square feet) or even a hectare (approximately 100,000 square feet), the impact of the glazing becomes far less significant, and overall energy efficiency improves substantially.

Heating: Most gutter-connected greenhouses are heated using boiler systems that circulate hot water. Heat is typically distributed around the perimeter of the structure and beneath the growing beds to maintain warm root zones. Some smaller facilities instead use gas-fired unit heaters to heat the air directly.

Ventilation: The majority of gutter-connected greenhouses rely on roof venting to release excess heat, with wall vents allowing cooler, fresh outside air to enter. Some facilities also use exhaust fan systems, which may include evaporative cooling. While fan-based systems offer greater control, they come with higher operational costs compared to passive roof venting.

Gutter-connected greenhouses manage airflow and humidity through several methods. Many rely on passive ventilation using the stack effect, in which cooler air enters through lower wall openings and warm, humid air exits through roof vents at the peak of the greenhouse. This approach can also support dehumidification through a technique often referred to as “burping,” where vents are briefly opened and closed based on humidity levels to release moist air and reduce overall humidity.

In facilities that use exhaust fans, airflow typically moves from endwall to endwall. Depending on the capabilities of the greenhouse control system and the fans themselves, dehumidification can be handled in a similar manner by operating the fans for short intervals as needed to lower humidity levels.

While it is difficult to provide pricing for a theoretical greenhouse, gutter-connected greenhouses are often more affordable than higher-end greenhouse structures that use more expensive materials. That said, every project is unique, and total costs can vary widely depending on the materials, equipment, and systems selected.

Yes, gutter-connected greenhouses can be expanded over time. Expansion is typically easiest when using the same manufacturer as the original structure to ensure compatibility, but it is also possible to connect additional sections from a different manufacturer with proper planning and design.
