The Sealed SunChamber™
The SunChamber™ is a completely sealed grow environment. While our vented and sealed greenhouse options are essentially identical in design and materials (see HighYield™ Kit), the SunChamber™ is characterized by its sealed design, coupled with an EcoPack™ or EcoLoop™ HVACD option and a SunSense™ controller. Layout choice will depend on engineering, site considerations, budget, climate, etc.

Vented Greenhouse? Or Sealed SunChamber™?
How do I choose?
Before we decide on the best HVAC(D) solution for your growing need, the first question to address is whether a sealed (SunChamber™), or vented greenhouse is the better option, this will determine which environmental control options will be applicable. Ceres uses two proprietary, energy-saving HVAC(D) systems for our sealed grow facility options; EcoPack™ and EcoLoop™, and the GAHT® for our vented system. See below for the benefits of both systems.
Vented

A vented greenhouse can be provided with low capital and operational costs. It is a good option in places where smell is not a concern and precise control over temperature and humidity is not necessary.
SunChamber™

A sealed greenhouse (The Ceres SunChamber™) is intended for high-value crops. It is characterized by its extraordinary climate control capabilities, as there is no outside air exchange.

What is included with a Ceres SunChamber™?
- The EcoLoop™ geothermal HVACD system or EcoPack™ system
- Ceres automated SunSense™ Controller for monitoring & optimizing environmental conditions
- A fully sealed facility, adhering to fundamental Good Manufacturing Principles (GMP)
- Ozone water treatment & water reclamation
- Supplemental CO2 (intended to help plant growth)
- Fertigation systems
- Customized grow systems, biosecurity, air purification, and clean in place (CIP) sanitation systems
Greenhouse Technology
One centralized system for controlling the whole environment. Monitor temperature, relative humidity, and CO2, leaf/ canopy temp, PAR, lighting zones, and outdoor weather.
We offer Ceres designed EcoLoop™ or EcoPack™ HVAC options depending on growing goals, budget, site constraints, and greenhouse type. All Ceres environmental controls are custom integrated to suit your needs.
The GAHT® system is a ground to air heat exchanger, a system often referred to as a ‘Climate Battery’. Ceres leads the industry in climate battery technology, having designed and installed more systems in greenhouses than any other company in the world.
Different crops may demand specific lighting requirements. We offer a variety of lighting solutions designed to suit the needs of each individual operation.
A NetZero greenhouse will have zero net emissions. This goal is achieved through capturing and storing energy. This can be done using a various system options.
Ethylene tetrafluoroethylene is a durable, high light transmissive glazing option. It offers more than 95% light transmission, including the UV spectrum. More than other greenhouse companies, Ceres is implementing full spectrum glazings for maximum crop growth.

Sunchamber™ FAQs
The Sunchamber™ is a completely sealed Ceres greenhouse with the EcoLoop™ geothermal (or EcoPack™) HVACD system and the Ceres SunSense controller, intended for the most energy efficient and highly controlled environment. This system is intended for high value crops that require precision climate control.
While the vegetables would love this environment. It is usually not necessary nor cost effective to employ a fully sealed greenhouse for commercial vegetable production. A vented Ceres greenhouse with smart controls can still provide precise grow conditions which is more than sufficient for commercial agriculture.
For a fully built structure (including all estimated construction costs) ready to grow we estimate $210-$260/sqft.
