You planted every one of them.
The roses your mother gave you. The lemon that took three years to fruit. The lawn the dog ruined twice.
Maali · GARDEN CARE
Hand your garden to someone who truly knows it.
A gardener that knows your soil. It watches the weather, learns what your garden needs, and gives every bed exactly the water it needs, and no more.
No account. No cloud. No subscription. Just smart watering that takes care of itself.

Then you handed the watering to a company.
It reads the forecast and skips the rainy days, and it needs an account, a subscription and a working connection to do any of it.
It is clever. It is not yours.
Or you hand it to Maali.
Maali means gardener, and this one is yours the way a spade is yours. It waters as well as the clever ones, decides in your garage on your own Wi-Fi, and asks nobody’s permission. Every part on its list has a catalog number and a shop that still sells it.
Bought once. Kept for good. If whoever makes it walked away tomorrow, your garden would not notice.
● What changes
Same garden. Different arrangement.
THE SCHEDULEStart days, start times, minutes per zone. You work out when to water, and then you work it out again every time the season turns.
THE SCHEDULEYou don’t have to write one. Tell it what grows in each bed and hand the yard over: it chooses the times itself, working back from sunrise so the watering finishes before the sun is on the garden, and the hour moves through the year as sunrise does. Or write your own schedule — programs are still there, and Maali gives the clock straight back and carries on deciding how much each bed gets. Change your mind either way, whenever you like.
THE ACCOUNTAn email, a password, and a plan that grew a little each year. Your watering schedule lives on a server you will never see.
THE ACCOUNTThere isn’t one. Nothing to sign into, nothing to lapse, and nothing anyone can discontinue.
THE OUTAGEWhen their servers are down, or yours is, the clever part stops. The garden waits on somebody’s status page.
THE OUTAGEIt decides on the wall, on your own network. Cut the wire and it keeps watering from what it already knows.
THE STUCK VALVEIf the brain hangs with a valve open, some software somewhere has to notice, and then reach your yard to act.
THE STUCK VALVEThe valve is held open by power. Power stops and a spring closes it. No code involved, nothing to notice.
YEAR SIXSupport ends, the app is rewritten, the hardware is sealed. You buy the next one.
YEAR SIXEvery part is a catalog part with a number. When one dies it unclips from the rail and the new one clips on.
Don’t take our word. Watch it think.
● The receipt
Twenty-one days of heat. It chose to water eight times.
Real Sacramento weather from July 2024, replayed through the code that opens your valve. Watch it let the soil dry, sit out the cooler days, then decide a bed has earned a long drink.

This is not a picture we drew to look nice. We picked the hard week on purpose, and ran it through water_balance and schedule_engine the device ships with.
● Safety
No matter what, the water stops.
A watering computer can make exactly one unforgivable mess: water that will not stop. So pick a disaster, and watch which layer is still standing when it lands.
Pick a disaster.Each one lands on a different layer, and the water stops every time.

Ready for the yard you have, and the one you’re planning.
Every line ships in the same box, on the same parts. There are no upsell tiers.

● Build it
One afternoon, five modules, and the wires already in your wall.
Every part clips onto one rail, and clips off again. $179 for the parts that water, ordered once, and $353 if you fit every sensor and surge module. Everything on the list is a part you can look up.
The scariest wire you will touch carries 24 volts.

I WANT ONE
There is no shop. Not yet.
Maali is open hardware. Free to build, and built by hand today. If enough people ask, one gets built. So ask.
- Water that follows the weather, and a bed’s own soil
- No account, no cloud, no subscription, ever
- No matter what, the water stops
- Parts you can buy in year eight, and swap yourself
Put your name down.
One message, when there is something real to say. Not before.
Thank you. One question, if you don’t mind.
It decides what gets built next, and honestly whether a finished unit gets made at all.
Worth saying plainly: the firmware runs a real garden every day and the hardware is proven. There is no company building, testing and warranting units. That is what your money would buy.
Then it is already yours. Five steps and an afternoon, using the wires already in your wall. We’ll write when the parts list settles, so you order once.
