It starts with the plant

Every medicine begins with a single thing: the plant. A formulation can only ever be as good as the cannabis it starts from — so the starting material matters more than almost anything else. That belief is why Diamond Medicine Technologies cares so deeply about where its flower comes from, and it is why we point to Green Horizons.

The desert was never supposed to grow medicine

In California's Coachella Valley, the sun shines nearly 300 days a year. For most of farming history, that relentless desert sun was treated as a problem — too hot, too harsh, too extreme for a delicate crop like cannabis. Two men looked at the same desert and saw the opposite: sacred ground, bathed in light, where world-class flower could be grown under real sunshine at a scale that could finally make clean medicine affordable.

Almost no one believed it could be done. The heat alone scares off traditional growers, and the doubters were everywhere. But the founders held the vision through roughly eight years of planning, permitting, and construction — and they never let go of it. In May 2024 they cut the ribbon on the first phase of the campus: a $65 million investment, and only the beginning.

Inside Green Horizons

Green Horizons is a sun-grown, light-assisted, climate-controlled cannabis campus, with a planned footprint of one million square feet. The desert sun does the heavy lifting; modern FOHSE LED lighting keeps the canopy consistent day to day; and instead of energy-hungry air conditioning, the facility uses evaporative cooling to hold a perfect climate in the desert heat. A Neatleaf "Spyder" AI system watches over every plant in real time.

Here is the twist the doubters missed: the desert is not the obstacle — it is the gift. Because the sun does most of the work, the energy footprint is a fraction of a traditional indoor farm. That means a lower cost of goods and a higher yield at the same time — the exact combination the industry has chased for years. The first 100,000-square-foot phase opened in 2024 and is built to produce around 35,000 pounds of premium sun-grown flower a year: clean, consistent starting material, grown with an extraordinary amount of care.

The souls behind the vision

To understand Green Horizons, you have to understand the two men behind it — because this was never only a business to them. It was a calling.

Carlos "Los" Arias, co-founder and CEO, is a true cannabis pioneer. He earned his law degree, but his path was never about practicing law — it was about vision. He saw what this plant could become long before the world caught up, and he built at the frontier when few others dared to. Los is an entrepreneur and a builder, but at his core he is a medicine man: someone who treats the plant as sacred, who guides people gently toward healing, and who carries the whole endeavor with humility and intention. He leads from a place of service, not ego — and you feel it in everything Green Horizons does.

His partner, Michael Meade, is a self-made developer who could see a future no one else could. He looked at the Coachella Valley — sunshine, music, and rich agricultural soil — and envisioned a "Napa Valley of the South" for cannabis. Where others saw empty desert, he saw fertile, sacred ground for something new, and he had the conviction and the discipline to make it real, laying the groundwork that turned the region into a genuine cultivation hub.

Both men are cancer survivors. Both found real comfort in cannabis during the hardest chapters of their own lives, and both carry that gratitude forward as humanitarians — giving back, lifting others up, and staying grounded in why they began. They are, quite simply, beautiful human beings: two people who turned their own healing into a mission to bring sun-grown medicine to the families who need it, not only to those who can afford it.

SOL — fashion meets flower

Green Horizons' first in-house brand is called SOL — "sun" in Spanish — a tribute to the desert light that grows it and to the Coachella Valley's deep agricultural roots. SOL is premium but accessible, and it reaches beyond the dispensary: the brand is launching a hemp-based apparel line as part of a broader "fashion meets flower" vision, and it gives back through the One Acre Project to help preserve the Amazon Rainforest.

The vision drew a remarkable believer. Fashion icon Tommy Hilfiger came on as a founding partner and investor, lending his branding power to a cannabis company built on sun, soil, and intention.

Why it matters to us

Great medicine starts with great plants. Green Horizons represents exactly what Diamond Medicine Technologies believes in: cannabis grown in real sunlight, cleanly, consistently, and at a scale that makes healing affordable. Sun-grown flower at an honest cost is the foundation that makes formulations like Jenny's Rose possible — medicine that can reach the people who need comfort and relief, not only those who can pay a premium.

Two cancer survivors bet everything on a desert that nobody believed in. What they built is proof that doing it the right way — with patience, integrity, and respect for the plant — can also be the wise way.

Great medicine starts here.
