A Father-Son Agriculture Venture in New Milford Piques the Interest of a NASA Scientist.

I
tend to think in pictures.” That is how New Milford’s Mack
McAleer began to answer my question about the “aha” mo-
ment behind his agricultural growing invention.
After the passing of his mother eight years ago, Mack found
himself in the attic of her Atlanta home sifting through nearly
a hundred years of accumulated treasure. He discovered a large, dusty
stack of old Scientific American magazines, and curiosity led him to
skim through several editions from the 1950s and 1960s.
On his flight home to Connecticut, he delved into a story about a
NASA research project aimed at understanding the impact of gravity
on plant growth. Curious, he studied the pictures of the equipment
used in the research and was puzzled by their design. He thought,
“Why did they do it that way?”
“It was one of those things that just rattled around in my head,”
recalls Mack. “A year or so later, I saw a piece of culvert pipe, and an
image popped into my head. Soon thereafter, I found myself on the
back deck making the first prototype.”
GROWING A NEW TECHNOLOGY
Mack invented a soil-filled, centrally irrigated cylinder that revolves
around a static axle. After having initial success growing vegetables
with it, he dug around the internet to see if anything like it existed. He
didn’t find anything. That’s when he told his son, Mackenze, who was
living and working in Panama at the time, what he was up to.
“It was kind of a big deal for my father to tell me, ‘You need to come
home and see this,’” Mackenze says with a grin. When he returned to

New Milford for a visit and saw the
system, he became intrigued. After
studying its potential impact for the
agriculture industry, Mackenze’s
intrigue turned to excitement.
He decided to leave Panama and help his father turn the invention
into a business. They named the company “Arise” and now have a
patent-pending design that is attracting international interest.
The Arise cylinder is a geotropic growing system. Geotropism
is defined as “the growth of plant organs in response to gravity.” A
plant’s main root is positively geotropic, meaning it grows downward
in the direction of gravitational pull, while a main stem is negatively
geotropic and grows in the opposite direction, against gravity’s pull.
Think of a potted plant that tips over on its side. If left in that posi-
tion, the growing parts of the stem will eventually curve upward and
grow vertically again.
This biological effect is what contributes to the efficacy of the tech-
nology. Because the cylinder rotates slowly, the team believes plants
detect the change in gravity and invest their energy in growing stron-
ger root systems and stems in order to support their weight as the
cylinder continuously spins them around.
“There’s no question our technology grows plants well; the real
question is, what are the empirical claims versus other technologies
and traditional farming methods?” says Mackenze. “We intend to
demonstrate, through research, that it grows bigger plants, faster, and
with higher nutrient density.”
Its key differentiator is that it is a scalable, soil-based system. This
distinction attracts the attention of scientists and sets the Arise geo-
ponic technology apart from hydroponic, aeroponic, and aquapon-
ic systems. “Across the board, we’re more resource efficient. There’s
nothing else that is self-contained and soil-based that can go vertical,”
notes Mackenze, in reference to indoor growing technologies that
build upward, allowing for an exponential increase in growing capac-
ity by using vertical space, rather than being confined solely to the
square footage of the floor.
Because of its centralized irrigation design, virtually 100% of the
water goes directly to the plants. “The only water loss in the system
is through transpiration – when the plant leaves breathe out,” states
Mackenze. “Not even drip irrigation can compete with that.” And
because the system is soil-based, the range of plants that can be grown

includes root vegetables like potatoes or carrots, and perennials, none
of which grow well in aeroponic or aquaponic systems.
FROM VISION TO REALITY
Not long ago, the Arise journey hit a new milestone when Mackenze
met NASA’s Dr. Gary Stutte at an agriculture conference in Panama.
Dr. Stutte works at the Kennedy Space Center and is the principle
investigator for space flight experiments designed to grow plants in
microgravity. He is also founder of the American Council for Medici-
nally Active Plants.
Sensing a once-in-a-lifetime opportunity, Mackenze struck up a
conversation. When shown a picture of the cylinder on Mackenze’s
phone, Stutte responded, “That thing would grow herbs like crazy!”
Soon afterwards, Arise had the pleasure of welcoming the NASA sci-
entist as a new team member and advisor.
The momentum continues to roll. The company recently partici-
pated in Village Capital’s accelerator program in Louisville, KY. The
program focuses on impact investing to help companies developing
sustainable agriculture technologies.
That experience helped open doors. Arise is working with one of
the largest greenhouse supply distributors and with the largest garden-
ing distributor in the U.S. to develop project plans for commercial
applications from the home to the large-scale farm.
“Our goal is to build our own commercial greenhouse and central-
ize R&D in one place to construct cylinders for our research partners,”
states Mackenze. To accomplish that, they seek to raise capital with the
right investor. While they’ve had several offers to consider, the father-
son team is taking a diligent approach to finding a cohort who not only
shares their business vision but also their social impact vision.
Meanwhile, until they ink a deal, Mack continues experimenting
in his backyard greenhouse. He plants roughly three different crop ro-
tations on his cylinder during the summer to better understand which
plants seem to benefit most from the technology.
“It’s hard to remain patient when you feel you’re on the cusp of a
game-changing innovation that can make such a meaningful differ-
ence,” says Mack as he inspects his current crop of lettuces and herbs
slowly spinning on the cylinder. “Our system removes the need for
special skills, making it feasible for anyone to grow,” Mackenze says
enthusiastically. “By crowd sourcing the knowledge and making this
an open-sourced technology, the opportunities for positive social and
environmental change are seemingly endless.”
