Introducing the EcoLoop™:  Ceres Most Energy-Efficient Heating and Cooling System Yet 

At Ceres we are challenging the idea that “high tech” means “expensive” when it comes to greenhouse design. Between our patented passive solar structural design and our Ground to Air Heat Transfer (GAHT™) System, innovation is at our core and we aim to provide growers with the most energy-efficient growing solutions. We help our growers…

A Greenhouse for Cold Climates, Eh?

Not all greenhouses are created equal. Variance in greenhouse design, heating systems, and structural materials make certain greenhouses more applicable for colder climates than others. For instance, a hoop house might be a great season extender for a grower in the Pacific Northwest, but it couldn’t withstand high wind and snow loads that occur in…

Setting Controls in a GAHT System or Climate Battery

A climate battery is a ground to air heat exchanger, which provides year-round heating and cooling of solar greenhouses and other structures using the thermal mass of the soil underground. Ceres’ patent-pending Ground to Air Heat Transfer (GAHT™) is a high-performance climate battery specialized for year-round greenhouse growers. For more on how a GAHT™ system…

10 Do’s and Don’ts for Designing a Ground to Air Heat Transfer System

A Ground to Air Heat Transfer system– also called Earth Tubes or a Climate Battery – is a low-cost method for heating and cooling your greenhouse year-round using only the sun and the thermal mass of the soil underground. For more info on how it works, see our GAHT page here. A GAHT system is…

3 Ways to Heat Your Greenhouse for Free this Winter

Learn how to harness and store solar energy to keep your greenhouse growing through the winter for free (or next to nothing) Greenhouses can be interesting environments to grow in. This is because standard greenhouse materials like glass and plastic (“glazing”) are extremely good at letting in light and heat in, and extremely good at…
