01 · The shell
Built in a factory, put up anywhere
Insulated panels, made and tested in Hyderabad, then installed and commissioned on your site. As one 42 m² container or a whole hall.
GrowRushIndoor farms
Grow fresh food where farms can’t.
Indoor farms from a single 42 m² container to a campus of halls. Sealed from the weather, run by FarmOS, harvesting every week of the year.

9.2 Lof water per kg grown, nothing discharged

What you get
What every GrowRush farm does.
The same six systems in every farm we build, from one container to a full site.
02 · Climate
Set to the crop, held there
Temperature held within half a degree through the whole cycle. Fans on every tier keep air moving through the leaves. The weather outside never reaches the crop.
03 · Fertigation
Feeding on its own
EC and pH are measured all the time. Four dosing channels top up what the crop takes, so nobody mixes nutrients by hand.
04 · Lighting
Our own LED lights
Built for yield and for low power use. Spectrum, intensity and day length set for each crop and each growth stage.
05 · Sensing
Every variable, logged
Temperature, humidity, CO₂, airflow, EC and pH, read on a fixed interval, stored in FarmOS and watched by our agronomists.
About FarmOS
06 · Handover
Handed over producing
We run the first cycle with your team and train them on the job. You take over a farm that is already harvesting.
Anatomy
Inside the farm.
One aisle of a working GrowRush farm. Pick a part to see what it does.
01 · Nursery racks
Seedlings start in trays on their own racks and move to the growing channels once they are big enough, so channel space only ever holds plants that are growing.
02 · LED tier
A bar of our LED lights over every tier, close to the leaves. Spectrum and day length change as the crop moves from one growth stage to the next.
03 · Growing channels
NFT channels. A thin film of nutrient water runs past the roots and back to the tank, so the water is used again and nothing is discharged.
04 · Feed lines
Lines carry dosed nutrient water from the tank to every channel, with a valve on each one.
05 · Air movement
Fans on each tier move air through the canopy, so the top tier and the bottom tier see the same temperature and humidity.
06 · Service aisle
Wide enough for a trolley and a lift. Every tier can be reached for sowing, checks and harvest.
Scale
From one container to a campus.
Every GrowRush farm uses the same racks, lights, dosing and recipes. What changes is the building around them.

A single container
One farm on a 12 × 3.5 m pad. It needs no nursery, water room or packhouse, so the site is the footprint. For local retail supply, a demonstration or research.

How it compares
The weather stays outside.
The same crop, grown three ways.
| Measure | GrowRush | Standard greenhouse | Open field |
|---|---|---|---|
| Temperature | Set to the crop and held to ±0.5 °C, whatever the weather. | Follows the outside, swinging 9 to 13 °C from day to night. | Whatever the weather brings. |
| Pests | Sealed doors, no vents. Nothing sprayed. | Has to ventilate, so spraying is still needed. | Sprayed. In one study 19% of conventional lettuce broke residue limits. |
| Water | Recirculated. 9.2 L per kg, nothing discharged. | Depends on the system. | Lost to the ground and to evaporation. |
| Harvests | 12 a year, the same every month. | Above 25 °C, temperate crops lose taste and texture. | 1 or 2 a year, tied to the season. |
| Shell | Insulated panel, 20+ years, rated for site winds. | Plastic film, re-clad every 3 to 5 years. | None. |
| Who runs it | FarmOS plus trained operators, 3 for every 10 units. | An agronomist on site. | An agronomist, and the season. |

Questions
Before you enquire.
Is GrowRush only a container?
No. The 42 m² container is the smallest GrowRush farm. The same racks, lights, dosing, recipes and FarmOS go into purpose-built halls and multi-hall sites, which can be built in phases.
What can I grow?
Leafy greens, herbs and berries such as lettuce, basil and strawberries, each on a recipe proved on our own farms. Seed comes from our Seed Genetics range, bred for indoor racks.
Who runs it day to day?
Your team, trained on the job during the first cycle. Three operators run ten units, with our agronomists watching through FarmOS.
How long until the first harvest?
About four months from enquiry, including survey, build and commissioning.
How do I buy one?
Through our partner in your country. Send an enquiry and we will come back with a layout and a proposal. Freight, import and site works are quoted separately.
