​We design HVAC systems tailored to meet the needs of your indoor farm, allowing growers to manage plant responses, improve crop productivity, and increase profitability. Whether you're operating an existing indoor grow, designing a state-of-the-art vertical farm, planning a new greenhouse complex, or investigating all-of-the-above options, we can help.

Greenhouses, vertical farms, mushroom production facilities, indoor gardens, and other indoor plant production operations allow food to be grown anywhere in the world, in any climate, on rural lands and on-top city roofs.  Indoor food production systems require careful planning and design, as well as a good grower to optimize plant growth, maximize profitability, and minimize environmental impact. To grow plants successfully indoors, a broad spectrum of technology is required, including climate control systems.  HVAC (heating, ventilating, and cooling) systems are used to control the temperature, humidity, air distribution, and carbon dioxide levels inside the growing structure.  

No matter what type of cultivation facility you use, having a better understanding of the crop-environment interactions and designing the HVAC system accordingly, will improve crop yields and quality, reduce losses to mold and moisture, use less energy and water, and minimize operation and maintenance costs. 

Nadia Sabeh​​
PhD, PE, LEED AP
​Owner, Founder of Dr. Greenhouse, Inc.

Dr. Nadia (A.K.A. “Dr. Greenhouse”) is President and Founder of Dr. Greenhouse, Inc., an agricultural and mechanical engineering firm that specializes in the design of HVAC systems for indoor plant environments. Dr. Sabeh first became interested in controlled environment agriculture (CEA) as an undergraduate, while working on a small shiitake and oyster mushroom farm in southern Idaho. She was inspired by the farmer’s way of life – the daily rhythm, the appreciation for the land,  the hard work necessary to grow a crop, the friendly competition, and the respect and camaraderie between growers, helping each other to troubleshoot problems, fill orders, and make money. It was then that she decided she wanted to use her engineering know-how to help farmers control their environments. More than 20 years later, she is still on that path,  helping farmers grow crops indoors, in greenhouses, and in locations that would otherwise make it impossible or impractical to do so.  

Dr. Sabeh has her PhD in Agricultural Engineering from the University of Arizona’s Controlled Environment Agriculture Center (CEAC) and is a  licensed Mechanical Engineer. She authored the book Tomato Greenhouse Roadmap and contributed two chapters to the book Plant Factory. While regularly invited to speak at conferences and to professional organizations around the world, she has also been featured in and written articles for several industry-related magazines.

Dr. Sabeh is also the Co-Chair of a new ASABE/ASHRAE co-sponsored committee charged with developing the standard “HVAC for Indoor Plant Environments without Sunlight.” Hoping to bridge the two worlds of engineering and agriculture was always her dream...and still is. She hopes that bridge better serves our clients and, more importantly, cultivates understanding within the CEA industry.

Lydia Palma Miner
​Engineering Designer
​

Doctoral candidate, Lydia Palma Miner is our Engineering Designer, and so much more! Having grown up in the country riding horses and gardening, she has continued to pursue those passions personally, academically, and now, professionally. An avid gardener, she even held her recent nuptials in her backyard, amongst the flowers, trees, and other plants that she and her partner planted and cultivated. 

Lydia's passion was enhanced when she pursued her mechanical engineering degree at CSU Sacramento, where she designed and built a biodiesel conversion system using waste cooking oil from eateries on campus. It is no wonder that her agrarian upbringing and interest in environmental sustainability culminated in her pursuit of a PhD in Biosystems Engineering from UC Davis. She is currently finalizing her PhD dissertation on Black Soldier Fly Larvae (AKA: maggots) and their effectiveness in breaking down waste and becoming a nutritious source of feed for chickens. 

Unintentionally, her PhD work has started to warm her up to worms (which she had always hated!), and more importantly, led her to Dr. Greenhouse, Inc., where she makes sustainable engineering solutions a reality for clients. Lydia finds the work of optimizing a facility to maximize production rewarding and necessary, especially with our planet's increased need for sustainable solutions. Just as diverse as the crops and problems of our clients, so are the solutions that Lydia and the Dr. Greenhouse team strive to offer.

​Janan Sabeh​ Director of Marketing

Janan is our team’s Marketing Director, focusing on client relationships and brand management as well as anticipating the needs of our growing business within a dynamic agriculture industry. As farmers and cultivators try to determine if they should grow indoors, navigate the technology and sustainability challenges of agriculture, and wade into the world of legal cannabis, Janan emphasizes the relevance, timeliness, and benefits of Dr. Greenhouses’ services to the CEA  industry. 
 
With a B.A. in International Politics and Public Service, Janan is passionate about food quality and security around the world. At Dr. Greenhouse Inc., Janan brings a global perspective to our already meaningful work. Having lived in the Middle East for 11 years, Janan became fluent in Arabic and lived in rural areas, where farming is the backbone of the economy, and sustains families, communities, and the region at large.  As famine, malnutrition, and water scarcity persist around the world,  she hopes that Dr. Greenhouse will be able to help those most in need gain access to quality food year-round.
 
Janan looks forward to meeting and collaborating with all of our clients, both locally and globally.
