An indoor putting green that’s like the real thing
There’s nothing golfers enjoy more than perfectly manicured putting greens.
You know the ones — the silky smooth surfaces that are usually reserved for pros and top private clubs.
But no matter what course a golfer plays, his or her greens are never pristine year round. Maintenance and climate take a toll on even the best natural greens.
Yes, synthetic putting greens have improved significantly in the last decade, but the ones that most closely mimic real greens are complicated to install and require constant maintenance. Well, not all of them, actually.
Meet “The Only Green,” a standalone, no-maintenance indoor putting green that allows golfers to raise individual parts of the green’s surface to create different combinations of breaks. Its 4-foot-by-20-foot green has 3 million different break configurations, which means a golfer could putt on a slightly different green every day for about 8200 years.
Tim Ummel, co-founder and managing partner of The Golf Tank, the company that owns The Only Green, says the secret to the product is its special construction that not only allows golfers to quickly and easily create putts with different combinations of breaks — its proprietary surface allows the ball to roll in a way that’s indistinguishable from the best greens in the world.
Ummel and Golf Tank partner Mike Helfrich are golf industry veterans — Ummel has spent 20 years in various golf businesses, while Helfrich was one of the original employees of HotStix, a Scottsdale-based custom club fitting facility.
Their deep rolodex of industry connections led them to form The Golf Tank in July 2012, which was inspired by the ABC reality TV show “Shark Tank.” The Shark Tank features a panel of entrepreneurs, headlined by Dallas Mavericks owner Mark Cuban, who invest in the products and businesses of other entrepreneurs.
Like Shark Tank, Ummel said The Golf Tank plans to invest in ideas and companies where they see growth potential. The Only Green, for example, ranges in price from $3,295 to more than $10,000, which differentiates it from other indoor putting greens.
“We know how to market to those kind of customers, Ummel said. “We’re also looking for equipment that everyone has got to have . . . products like the Olimar Trimetal that completely revolutionized things.”
The company’s first order of business was purchasing a company called “Dream Green,” which was the The Only Green’s old name. Dream Green inventor Rocklin Duffy actually began making his high-end indoor putting greens in 1989. But he was the only one making the greens, so production took seven to nine weeks. That meant that Dream Greens were largely a secret in the golf world.
In September 2012, The Golf Tank officially purchased Dream Green from Duffy, 67, and his wife Lisa. The founders then spent four months creating tooling that kept the greens the same, but allowed them to be produced much faster — in about seven days.
The Only Green launched in January and is sold out of The Golf Tank’s 4000-square-foot Scottsdale-based headquarters, a discreet facility located nearby the Scottsdale Air Center. It’s is available in four different sizes that take their names from famous golf architects: The Ross (2×8), The Old Tom (3×12), The MacDonald (4×12), The Tillinghast (4×16) and The MacKenzie (4×20).
The 2-foot-by-8-foot model will set golfers back $3,295 with a hard maple or ash wood base, while darker natural woods such as cherry, walnut, hickory and bubinga cost $200 more. The MacKenzie, the largest model, has a starting price of $9995. For all the models, custom lengths, headboards and enamel paint logos are available for additional charges as well.
Ummel said that he is pleased with sales of The Only Green so far, and has interested buyers that range from homeowners who want one unit to high-end department stores that are looking to purchase several hundred units to put in the men’s sections of their department stores.

Slab city on the Korn Ferry Tour — Lead Tape Report
This week, we have our Tour Photographer, Greg Moore, on the ground at the OccuNet Classic at Tascosa Golf Club in Amarillo, Texas, for the 14th event of the 2026 Korn Ferry Tour season. With that, we see some great things in the Lead Tape Report as we roll into Amarillo.
Joel Thelen
Monday Qualifier, Joel Thelen is in the field this week. He has played on the Korn Ferry Tour for a full season in 2023, and he is back in action this week. A couple of clubs caught my eye this week in his bag.
First off: His trusted Titleist 816 H2 hybrid. This club came out in October of 2015, and it still remains strong in the bag. Also, take a look at this Odyssey White Hot OG 7, putting a capital S in the 7S model. This custom neck has some impressive lean for an arm-lock-style putter. The bottom of the putter is covered in tape for optimal weighting.





Mitchell Meissner
Taking a look at Mitchell Meissner’s bag this week, we have some great lead tape coverage. Top to bottom working from fairway metals, irons, and wedges. We can see on the short irons and wedges that there is tape at the base of the grip, adding a little counterbalance. Along with that, some tape on the short irons and wedges as well. Moving to his putter, he rolls the Odyssey 7 Bird putter. Meissner putts left-handed and strikes the ball right-handed.

- macedan: “Started with a hand-me-down Golden Bear set from my brother when I was in high school, never really played more than once a year or got into the game until about summer of 2017. First purchased a set of Cleveland CG4’s (I actually really miss this set sometimes, soft & not terribly large for a GI iron), moved into Nike Vapor Fly’s by the end of the year. Those lasted until spring of 18 when I decided I wanted new, so I traded them in for TM Rbladez. Honestly, although I liked the Rbladez, poor decision on my part, I think this was really about the only time so far that after a week or two I was kicking myself for not staying with what I had. Rbladez stayed with me until late last summer when I switched to P790’s and (knock on wood) I am hoping this will be my longest lasting set.”

That’s really nice, but when u start talking prices like that, def not in my budget for a practice green. I think I would get a membership at a nice private club and do my practice there. But you can’t have beautiful weather everywhere, so I can understand why some would want.
Just my opinion….
