In a flat in Palakkad, the salad bowl no longer depends on the season, the soil, or even the sun. It depends on a black cabinet about the size of a refrigerator, three shelves of lettuce glowing under LED lights, and a small Kerala startup that decided the kitchen garden could be an appliance. That startup is X Boson AI, and its CAAX Mobile Farming Unit — on show at Huddle Global 2026 — grows fresh vegetables with no sunlight, no soil, and no pesticides.

A farm the size of a fridge
The CAAX Mobile Farming Unit is a fully automated hydroponics system roughly the size of a refrigerator. The company says the nearly six-foot-tall unit holds three levels of plant arrangements, with saplings placed in food-grade acrylic base sheets containing the growing medium that supplies the nutrients the plants need. Each of the three sections is fitted with artificial LED grow lights, so the unit needs no natural sunlight at all — and, the company says, it needs no frequent maintenance either.
That combination is the whole point. With no soil, no sunlight and no pesticides or conventional fertilisers in the equation, a household could harvest fresh, organically grown vegetables from a shady corner of an apartment — a kitchen garden that fits anywhere a fridge fits.
A patented tray, built with a university
The CAAX unit grows out of an earlier invention from the same team. X Boson AI developed a modular hydroponic tray system together with Santosh Kumar M.B., head of the Department of Information Technology at Cochin University of Science and Technology (CUSAT), and the company’s CEO Pradeep Kumar P., working at the Maker Village in Kinfra Hi-Tech Park, Kalamassery, and CUSAT. The design has been officially granted a patent by the Government of India under the title ‘Hydroponic Device for Improving Plant Growth’.

Each tray can support up to nine plants and carries a fully self-contained nutrient reservoir, circulating nutrients continuously without external tanks or complex plumbing. The modular structure scales from a single tray to multi-unit setups, suited to home micro-farming, research applications and smart-city agriculture — the same engineering, from a countertop tray to a full cabinet.

From Palakkad to the national stage
X Boson AI began operations in 2022 in Palakkad, and in 2026 it was picked for Action for India’s AI+Impact Cohort, a four-month accelerator for twelve promising AI-driven startups. Now the company is showcasing the CAAX unit at Huddle Global 2026, the startup festival organised by the Kerala Startup Mission — taking a piece of farming hardware built in a small Kerala town to a national audience.
It is a quietly radical idea: that the freshest vegetables in a home could come not from a market or a farm, but from a cabinet in the corner, growing under its own light. X Boson AI has spent four years building the engineering to make that ordinary — a patent, a product, and now a farming unit that asks for nothing more than a plug socket and a little patience.
