Everything you need to keep your plants thriving comes with your sensor.

Yes - SmartyPlants supports all kinds of indoor plants, from low-light ferns to sun-loving succulents.

It's designed for houseplants of every shape and style, helping each one find its perfect balance.

No - you're all set.

Every SmartyPlants sensor includes a stem attachment. We also offer longer stems for deeper pots, giving you more detail if you'd like an extra layer of insight.

Not always. One sensor can guide care for several plants with similar needs.

If similar plants share the same light or humidity, one sensor gives insights for all.

For varied collections, adding an extra or two helps keep everything balanced, which is why we offer bundle options.

SmartyPlants starts learning straight away.

From the moment it's in the soil, the sensor reads moisture, light, temperature, humidity and nutrients. It'll spot anything that needs attention right away.

Over time, it builds a fuller picture of your plant's environment to further tailor insights.
