Ceres steel greenhouse kits are energy efficient growing environments for sustainable and abundant year-round growing. Using insulation, superior glazing and passive solar design our kits are capable of growing more, using less energy.

HighYield™ Kits

Ceres HighYield™ Kit is a stable, easy to control indoor growing environment. Our energy-efficient greenhouse design is created for maximum productivity, they are used in applications for which the highest yields are expected. Kits come in two depths: 23’ and 30’ deep and are scalable in increments of 4’.

The HighYield™ Kit is built with hot-dipped galvanized steel 2” x 4” framing sections, pre-cut to length. Along with IMPs, glazing and doors, greenhouse kits include exhaust fans and intake vents, sized to meet the cooling load of the greenhouse (depending on climate).

We ship all greenhouse materials to the job site and the greenhouse is erected by a local contractor. We recommend getting a Construction Manager to help in the construction process.

All of our HighYield™ Kits have an energy-efficient greenhouse design and are formed for modular capability, allowing for unlimited expansion without interruption, as well as the ability to operate multiple climates simultaneously.

Backyard Kits

Ceres Backyard Kits allow growers to be more self-reliant and sustainable by providing a space to grow food all year long. Sizes range from 120ft²-540ft² and are used for a variety of applications. Backyard Kits bring the efficiency of our commercial greenhouse kits to a smaller scale such as urban gardens and personal growing spaces. Every kit is engineered for local wind and snow loads and are built to last with galvanized steel framing.

Greenhouse Kits FAQs

Easy shipping anywhere in the US and Canada. If you are elsewhere please contact us for a shipping cost estimate.

You can install a HighYield™ Kit yourself, or hire installation out to a local contractor. You can also opt to have a Ceres construction supervisor oversee the construction process and direct your building crew.

This depends on your level on construction experience. Assembling a HighYield™ Kit requires significant construction experience and a crew of at least 3 people. You can get a sense of the steps needed to build a HighYield™ kit from our video. The following equipment and tools are required to install a HighYield™ Kit:

  • Riveter
  • Hammer drill
  • Boom lift with forks and cage
  • Circular saw with a metal blade
  • Corded impact driver

If you have experience with those tools, you can probably build a HighYield™ Kit on your own. We still recommend hiring one of Ceres Construction Managers to assist with the process.

Because each greenhouse is slightly different – tailored for your climate and growing goals—we provide custom quotes for all our energy-efficient commercial greenhouses. Pricing starts at $35 per sq. ft. for un-installed greenhouses. Please contact us to start a custom greenhouse quote.

Our Backyard Kits start at 12k. Due to the specific complexity of each project, prices on the website serve only as approximate amounts. Contact us to discuss your project.

Yes, we offer our own renewable heating/cooling system, as well as other climate control and growing systems.

Growing systems are customized according to growers’ needs, and specified after a consultation. Ceres can size, design and source:

  • Hydroponic and aquaponic systems
  • Light deprivation systems
  • Supplemental lighting, automated shade systems
  • Climate control and HVAC equipment
  • Monitoring systems

Roofing Kits FAQs

Yes, in addition to a polycarbonate greenhouse roof, we can source for you:

  • Phase change material (link)
  • Ventilation Systems: Exhaust Fans and Controls
  • Materials for our GAHT™ systems

We provide all materials for steel kits, or custom commercial greenhouses. For our residential solar greenhouses, the framing material is typically wood, and this is sourced locally, by you or a contractor. We provide DIY greenhouse plans, but do not ship wood framing materials.

Yes, we ship greenhouse materials to your site. In some cases, we may use a local distributor and have materials available for pick-up at a nearby store to allow for easier pick-up and cost savings.
