What it does

Plants. Watered. Precisely.

Not a timer that soaks everything on a clock. Pluvio gives each plant its own weighed dose, keeps to it whether you're home or not, and shows you exactly what it poured.

01

Your gardens, from anywhere.

Open your phone and they're all there — every plant, what it's had, what's coming, and how much water is left. You find out a plant is thirsty before the plant does.

02

It weighs what it pours.

How much water actually reached the plant — not how long a pump ran. Every watering is recorded exactly as it happened — did it water? is never a question.

03

The internet is optional.

Pluvio keeps its own schedule and waters on it whether or not anything is online. Router rebooting, Wi-Fi out, us having a bad day — your plants still get watered. The cloud is how you watch it, not how it works.

04

Set and forget.

Tell Pluvio what's in each place and how it likes to drink. After that it takes it from there — nothing to remember, nothing to open, no one asking whether anybody watered the fern.

What it grows

If it grows, it grows with Pluvio.

The right amount of water is the whole game — and no two plants want the same. Pluvio gives each its own: a windowsill of herbs, a tray of seedlings, a greenhouse bench, a cabin off the grid — each its own exact portion, on its own schedule.

Different plants, one promise: each gets exactly what it needs to grow. Rain, with a brain.

Meet the face of Pluvio. A virtual fishbowl with your own goldfish — always awake, always watching over your plants. Try me — tap the dial to water a plant. It's a simulation, so you won't waste a drop. 😉

Getting started

A code and an email address.

That's the whole of setup. There is nothing to type into the unit.

01

Enter the code on the box. It's printed on the outside, and it's yours. One entry, once.

02

Give us an email address. That's your account. Your unit is already waiting in it.

Fill the tank, tell it what you're growing, and you're done.

Rather stay anonymous? The email is optional. Pluvio keeps every plant on its schedule entirely on its own — no account, no cloud, nothing that needs your name. Giving an email only adds one thing: seeing your gardens from anywhere. Leave it out and Pluvio waters exactly the same — it just stays home with you.

The Lab

Built in the open.

Behind the calm fishbowl is this: a one-gallon jug rests on a load cell, so every pour is weighed as the water leaves it. The jug couples to a solenoid valve that drips onto a motorized arm below, which rotates to one of thirteen syringes — each with a barb connector running a tube to its own plant. It's a working prototype, not final industrial design; the patent-pending core is the combination — gravimetric dosing with a rotary, indexed dispensing arm. The maker version is fully open source.

The skunkworks

The root system.

What you see is the foliage — the small crew that tends Pluvio in the open. What makes it grow is the root system beneath: the growers, tinkerers and early believers who take it home and make it theirs. That’s where Pluvio really grows.

Every new grower is another root.
