What it does
Garden 01 automates the repetitive technical work that prevents many people from gardening successfully. The owner plants, refills supplies when necessary, and harvests.
Programmable LED lighting
Full-spectrum grow lights provide automatic daily light cycles tuned to the crop.
Water circulation
A pump delivers water to growing areas and returns it to a central reservoir for recirculation.
Automatic nutrients
Separate Nutrient A and B containers use small dosing pumps controlled by the system.
Environmental monitoring
Sensors track water level, water and air temperature, humidity, pH, and nutrient concentration.
Automatic water refill
An optional freshwater reservoir can replenish water as plants consume it.
Safety monitoring
Low-water detection and software limits shut down pumps or dosing when abnormal conditions occur.
The controller experience
At the center of Garden 01 is an inexpensive ESP32 microcontroller. Instead of requiring the owner to understand timers, irrigation schedules, and nutrient measurements, the controller makes routine decisions automatically.

Garden 01 — Growing Normally
The eventual experience could be: select a crop → fill water and nutrient containers → grow → harvest. The system sends alerts only when something actually requires human attention.
Designed for real food
Garden 01 intentionally tests crops beyond conventional countertop hydroponic gardens. Not every crop uses the same technique, so the system uses a hybrid modular approach rather than forcing every plant into identical channels.
Meal vegetables
Broccoli, cauliflower, cabbage, kale, bok choy
Fruiting crops
Compact tomatoes, peppers, strawberries, cucumbers, compact beans
Root crops
Potatoes, carrots, beets, onions in deeper substrate modules
Greens & herbs
Lettuce, spinach, basil, cilantro, herbs in high-density zones
Modular architecture
One of the most important parts of the project is expandability. Shelves, lights, and growing containers can be repositioned depending on the crop. A homeowner might configure one Garden 01 primarily for vegetables while another prioritizes tomatoes, peppers, and herbs.
Pathway to scale
Specs & target budget
A development target, not a guaranteed production cost. The prototype will determine true component cost, energy requirements, and reliability.
Footprint
3.5 ft × 2 ft
Height
Up to 7 ft
Controller
ESP32 microcontroller
Lighting
Full-spectrum LED grow bars
Power
12V system, solar-ready
Target budget
$300–$350 DIY
Conceptual budget
$300–$350
For the first DIY prototype, especially when reusing existing solar, battery, controller, or other components.
Development plan
Prototype 1 — Grow
Build the physical system and successfully grow several different crop types.
Prototype 2 — Automate
Integrate the ESP32, pumps, lighting schedules, sensors, water-level protection, and nutrient dosing.
Prototype 3 — Simplify
Reduce tasks for the user. Develop crop profiles and a simple phone dashboard.
Prototype 4 — Measure
Track water use, electricity, nutrients, harvest weight, crop time, failures, and cost per harvest.
Prototype 5 — Expand
Create larger indoor, outdoor, and community-scale modules based on what Garden 01 proves.
What we want to prove
Garden 01 is not based on the claim that a small indoor garden can replace someone's entire grocery store. It asks a more useful question:
How much nutritious food can we produce in a small amount of residential space when inexpensive automation removes much of the labor and technical knowledge normally required?
Every harvest can produce data about yield, water, electricity, nutrients, time, and cost. Over successive generations, those measurements can guide a better system.
Built on six principles
Affordable
Built around a $300–$350 DIY prototype budget using commodity parts.
Modular
Shelves, lights, and containers reposition for different crops.
Water-wise
Recirculating hydroponics uses less water than soil gardening.
Solar-ready
Designed to work with solar panels and battery storage.
Repairable
Standardized, off-the-shelf parts anyone can replace.
Expandable
One unit → multiple home modules → community growing systems.
