Growing Spaces
Gary Hall owns and runs Growing Spaces, the Pagosa Springs, Colorado manufacturer that has designed and built geodesic Growing Dome greenhouses for 35+ years, with more than 2,000 installations across 50 states and 14 countries.
His daily work puts him inside domes and on install sites: he tours the six domes on the company's campus, walks the production floor, works with customers on climate-specific configuration, and talks through long-term operation with owners who have lived with the product for decades. Gary writes from that first-hand vantage about passive-solar greenhouse design, the engineering of geodesic domes (including 115 mph wind and 120psf snow load ratings), polycarbonate glazing, thermal mass and above-ground pond systems, undersoil heat exchange, ventilation, and the realities of siting, installing, and operating a dome through its 30+ year service life. He also writes about year-round greenhouse gardening and how to adapt growing practices to a semi-controlled environment.
Gary acquired Growing Spaces in April 2025. He works closely with original founder Udgar and previous owner Lem Tingley, and considers himself the current shepherd of a 35+ year product legacy. He holds the CFA charter and an undergraduate degree in the hard sciences from Oregon State University.

Growing Spaces is now a Certified B Corporation
May 4, 2026
For a long time, we have said that a Growing Dome uses substantially less operating energy than a conventional mechanically heated greenhouse. The claim made sense to us. It fit the design, and customers could feel the difference. The B Corp process asked a harder question: can you document it?
On Pricing, Durability, and What We're Actually Selling
April 24, 2026
Most of what I know about money, I learned the hard way. One idea I kept coming back to was cost per wear: good leather shoes resoled a few times often cost less over ten years than a string of cheaper pairs. A solid hand tool that lasts decades is usually cheaper than replacing a weaker one every few years. That's the frame I bring to the question we get all the time: why does a Growing Dome cost what it costs?
Growing Spaces New Website
March 31, 2026
Our team has been hard at work on this for over a year, always with customers front of mind. We asked: when someone is trying to make a confident decision, what do they need? When an owner is caring for a dome through changing seasons, what should be easy to find and access? How do we serve people who love to explore on their own, without losing the “pick up the phone and talk to us” experience that sets us apart from larger greenhouse brands? Here is what is better now, and why I think you’ll enjoy it.
Growing Through Deep Winter: A Comparison of Greenhouse Approaches
February 6, 2024
Deep winter greenhouses (the Minnesota design) and geodesic domes (what we build) are the two most established solutions to growing through long cold winters. Here's how each approaches the problem, what they can and can't do, and what 30 winters of operating domes from Alaska to New Mexico have taught us.
