A vertical garden for the patio

Plant it. Pick it. Eat it.

It measures the water every second and fixes it on its own. You get the part you wanted: watching things grow, and dinner.

Two Garden of Eaten towers on a patio in morning light, one heavy with cucumber vines, a Weimaraner lying in front of them

The part you wanted

Lettuce that never saw a truck. Basil by the handful.

You do: drop in a seedling, pick, refill three bottles now and then.
You don't: test water, read charts, measure from bottles, guess.

Small space, real garden

A garden goes up, not out

Twenty lettuces in the ground want a four-by-five bed. On a tower they stand on a bar stool's footprint.

Drawn to the same scale. Ground spacing is the usual 12 inches for lettuce, basil and strawberries; the tower's floor space is the span of its feet.

Plant sites and floor space by number of towers
Towers	Plant sites	Floor space	Bed it replaces
One	15–20	about 1.7 sq ft	15–20 sq ft
Two	30–40	about 3.5 sq ft	30–40 sq ft
Three	45–60	about 5 sq ft	45–60 sq ft
Six	90–120	about 10 sq ft	90–120 sq ft

Five segments per tower, three or four sites each, all towers on one reservoir. We ran six for a season and ate from it.

The screen, in your hands

Walkthrough

Interactive demo The controller's actual screen. Everything on it works — tap the tabs, the gauges, the switches and the −/+ buttons.

A working replica: what you change here changes the screen, as on the unit. Readings are illustrative. The production unit carries this interface on a 7-inch daylight-readable panel.

How it keeps them healthy

Every part and what it does: the controller reads the pH, conductivity, water level and air sensors each second and drives three dosing pumps, the RO solenoid valve and the recirculation pump; the reservoir holds about 20 litres; the pump lifts water to the tower cap and it rains back down; phone and browser show the same readings (in testing); UV lamp optional on the production unit. Measures then acts; calcium and phosphate never meet; no cloud, no hub; power out the valve closes; built to live outside.

The complete system

One garden, ready to plant.

Controller and dosing unit, reservoir with its lid, one tower of five segments. Add towers and segments as you like; nutrients are not in the box — any two-part nutrient and pH Down.

Tower and reservoir are printed in-house in PETG for the first units.

Exploded view of the tower: the reservoir on its legs, five three-pot segments, the two-part feed cap on top, and a net pot at every port — Rendered from the production part files.

The production controller on its console reservoir: touchscreen showing pH, conductivity, temperatures, humidity and level; three dosing pump heads below it — Rendering of the production unit. Probes and dosing lines not shown.

Already growing?

The controller and reservoir, on their own.

Your towers, channels or buckets draw from this reservoir and return to it — a ¾-inch port on either side. The controller keeps the water in it right.

Run on our towers; not yet tested on other makers' systems — write to [email protected] if yours is unusual.

Where it stands

Built on the bench. Not yet in a box.

We are building the production unit now. Leave an address and we will write when it passes its seven-day soak — once, plainly, with the price. No deposit. No date we cannot keep.
