Leave your plants for weeks. Come home to them thriving.
A smart sensor reads light, moisture, nutrients and soil, then a quiet battery pump waters only when your plant needs it. Every healthy-plant day earns SAP tokens toward discounts.
Tech in the soil. Décor on top.
The Core does the sensing and watering. Everything else is there to make it beautiful: covers for the sensor, holders for the water jug, and custom pieces made from your images.
Unattended watering, measured by the plant itself.
The Core monitors the soil around the clock. When moisture drops below your plant's target, it runs a quiet pump that draws a measured dose from the sealed reservoir, and the sealed top keeps water from leaking or siphoning between doses.
Stake the Core
Push the sensor into the soil at root depth. It starts reading light, moisture, nutrients and soil temperature right away.
Fill the reservoir
Fill the sealed water jug, set it in a decorative holder beside the pot. The Core runs on a rechargeable battery, so there are no cords.
Let it pump
The pump waters in small, measured doses whenever the moisture reading says your plant is thirsty. You set the target in the app.
Earn while it grows
The app tracks water left, light and feeding, and every day your plant stays in range earns SAP tokens toward discounts.

Good to know
What is Plant To Earn?
Plant To Earn is a smart self-watering system for house plants. A soil sensor (the Plant To Earn Core) measures sunlight, soil moisture, nutrients and soil temperature and runs a quiet battery-powered pump that waters from a sealed reservoir only when the plant needs it, so you can leave for days or weeks. Each healthy-plant day earns SAP tokens, rewards you can redeem for discounts on select products in the Plant To Earn ecosystem. Decorative sensor covers and jug holders make the system part of your décor.
How does the self-watering system work?
The Core monitors soil moisture continuously. When it drops below the target you set in the app, the Core runs a quiet micro-pump that draws a measured dose from the sealed reservoir into a flow dispensing cup and perforated drain tubes, so the whole root ball is watered evenly. Between doses the reservoir's sealed top holds a partial vacuum, so water can't leak or siphon into the pot. The sealed-reservoir design builds on U.S. Patent 7,644,537, "Unattended plant watering system," by inventor John Hui.
What does the Plant To Earn sensor measure?
Four things: light (lux and daily light integral), soil moisture at root depth, nutrient level as electrical conductivity (EC), and soil temperature. The Plant To Earn app turns these into plain-language advice like "move closer to the window" or "feed this week."
Does it need power?
Yes. The Core runs a small water pump, and it's powered by a rechargeable battery, so there are no cords to the wall and a power outage doesn't stop watering. The app tells you when the battery is getting low. Wi-Fi is only needed for app updates and Rewards; watering follows the sensor even offline.
*Unattended duration depends on plant, pot size, light and reservoir size. The app estimates days remaining from your plant's actual readings.
