Open aeroponic tower · Offline-first · Measured ledger

Grow the city.
Feed the people.
Cut the carbon.

An open, offline-first aeroponic tower — engineered like an appliance, priced like a garden tool. Cherry tomatoes and greens in any room, with per-kg data that tells the truth about water, energy and carbon.

The tower · growy software

A modular aeroponic tower,
controlled end to end.

Roots in air, a precise nutrient mist, and a closed control loop that runs on the tower itself. growy software doses, lights, climates and records every harvest — on-device first, cloud when you want it.

  • Cherries, basil, microgreens and leafy greens in one footprint
  • Closed-loop water recycling: >90% of water reused, drain-back reservoir
  • Offline-first autonomy + OTA updates — runs with zero internet
  • Per-kg ledger: water, energy and CO₂e measured from stored telemetry

The industry's lesson · our answer

Sealed vertical farms burned billions. The tower grows differently.

The problem

  • High-capex vertical farms (AeroFarms, Infarm) raised $1B+ and still collapsed on energy and unit economics
  • Agrifood is roughly a third of global greenhouse-gas emissions
  • Produce travels 1,000+ km and loses flavour — and nutrition — on the way
  • Closed, proprietary hardware leaves owners dependent and unfixable

The solution

  • Low-capex towers: a €300 appliance, not a $20M building
  • Open hardware + 3D-printable parts — repairable by the owner
  • Offline-first control: the tower farms itself, cloud optional
  • A measured per-kg ledger — energy kept low by design, then proven by data
Business model

Three engines, one farm.

growy SaaS
€9–149 /mo

Farm control software for home growers and commercial operators: monitoring, dosing, yield analytics, carbon ledger.

Produce B2B
€/kg

Weekly subscriptions for restaurants and markets — vine-ripened flavour with a published per-kg carbon figure.

Farm-as-a-service
€5–20k

Design, install and operate towers for restaurants, hotels and schools — we run it, they keep the harvest.

Community city farming

Grown with the neighbourhood,
not just in it.

Each aerogrow site is a community farm: local harvests, workshops, school visits and a share of the produce for the people who live around it. Good food becomes a public good again.

“The farm isn’t a factory in the city. It’s the city growing its own food.”— the aerogrow team

Community financing · On-chain transparency

Funded by the people who eat the food.

The farm is financed by the people who eat its harvest — produce subscriptions and small grow-shares — and every euro sits on a public blockchain ledger: utilisation, milestones and farm accounting, verifiable by anyone.

Produce subscription
€240 /quarter

Prepaid seasonal baskets — the farm’s working capital. You fund the farm, you eat the harvest, delivered by cargo bike.

Grow-share
€100–1,000

Small-denomination participation through regulated crowdfunding: produce credits, harvest priority and a vote on what we grow.

Restaurant pre-orders
6-month contracts

Chefs prepay produce contracts — institutional demand financing the same public ledger.

On-chain, by default
