Compliant and fast Florida MMTC facility development
You won the license.
Now the clock to keep it is ticking.
The state gave you a window to get operational.
Miss it, and the license slips through your fingers.
the risk
Most new operators don’t fail at growing.
They fail at the build.
The timeline slips. The wrong parts arrived. The budget balloons before a single light is turned on. You need a facility that gets built fast, meets code, and is on budget.
know the odds
Don’t gamble on your build.
Play a hand that has already won.
Every builder says they can do it. Few have.

NEED A BETTER BIO I've been building Florida cannabis facilities since 2015; I started on the cultivation side before moving into the build aspect.
I spec the facility, manage the site work, and walk the inspector through the finished build. Start to finish, one person is accountable for all of it.

where each project starts
Two Options To Get Started
Bare land? Already own a building? The build looks different depending on where you start. We figure out which fits your site and timeline.
pre-fab
Built Off Site
The grow environment gets fabricated off site while your permits get approved. Once ready, they are installed on your property in a matter of days.
retrofit
Conversion On Site
You already own the building. I draw up the conversion plan and run it start to finish. If the structure turns up something unexpected, you're never figuring it out alone.
the build process
One Point Of Contact For Your Project
Most builds fall apart in the gaps; the designer hands off to a fabricator, the fabricator to a grow-systems company, and nobody owns the pieces between them. I don’t work that way. The crews I bring in are two I’ve run jobs with for years, and I’m part of every step — from the first drawing to your inspection.
I design it.
Green Horizons Consulting
Application support, facility design, the compliance program, yield and budget modeling. I solve the whole build on paper before fabrication starts.
I fabricate it.
B&K Installations
B&K builds the hard structure: fencing, gates, security enclosures, structural steel. They're a 47-year, AISC-certified shop capable of anything that comes up.
I build it.
Thrive Grow Systems
Thrive provides the grow environment: climate, irrigation, fertigation. I bring it together on your site and dial it in.
I finish it.
Green Horizons Consulting
I walk the inspector through the finished build and hand you a facility that's ready to run.
the track record
The hard part is never the same twice.
Every facility brings its own obstacles.
That’s why a track record matters the most.
A Produce Packing House
converted to
A licensed MMTC running a 4k+ plant cultivation operation.
Facility conversion, processing build-out, and a Phase 2 grow-room expansion. HVAC and fertigation managed through to a cGMP processing standard.
A Working Farm
converted to
An 80-acre, nursery-style cultivation compound.
Authored the application, SOPs, and forecasts; oversaw multiple construction projects and 12+ compliant product launches, packaging to production.
An Existing Nursery
converted to
A cGMP-certified MMTC, handed over ready to operate.
Cultivation, processing, and fulfillment procedures built under a strict timeline; SOP, security, and emergency binders authored; prepared for inspection and ownership transfer.
Why this matters now
Florida is about to be hit with new regulations and new licenses
A round of new MMTC licenses, the Pigford applicants, and existing operators weighing Schedule III retrofits — all of them face the same time crunch: a facility that has to be up to code fast.
I’m one person, and I take on a limited number of builds at a time. When this wave of licenses lands, the operators who reached out early are the ones who’ll have a slot. The ones who wait will be looking for help right when everyone else is too.
