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.

Why We Built the Growzebo™
August 23, 2026
I gave our team a price target and a rough picture of the customer, but no shape. They worked out the rest while building the first Growzebo™ about 20 yards from all six of our demonstration Domes.
Growing Spaces is now a Certified B Corporation
May 4, 2026
B Corp certification required us to document our energy claims and examine how we run the company. Some of the work confirmed strengths. Other parts exposed gaps in our records and practices. Here is what we learned.
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 spent more than a year rebuilding the website. I wanted people to be able to research on their own schedule, find the instructions for their dome, and reach us easily when they needed a conversation. Here is what changed.
Growing Through Deep Winter: A Comparison of Greenhouse Approaches
February 6, 2024
I compare Minnesota deep winter greenhouses, Growing Domes, and hoop houses through their heat storage, insulation, structural requirements, and intended use, with field accounts showing how growers adapt to different climates.
