How SmartyPlants works
Four simple steps.
SmartyPlants measures what you can't see
Light
Too little limits growth. Too much scorches leaves.
Temperature
Temperature swings stress plants. We track the changes.
Moisture and nutrients
Soil impacts everything: growth, nutrients and root health.
Humidity
Too low causes browning. Too high invites disease.
And tells you exactly what to do about it
Act with confidence, not guesswork.

FAQs
Is the app free?
Yes - the SmartyPlants app is free to download and use on iOS and Android. Everything you need to keep your plants thriving comes with your plant monitor.
Does it work with every kind of plant?
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.
Do I need to order stems seperately?
Every SmartyPlants plant monitor includes a standard-length stem attachment. We also offer longer stems for deeper pots, to ensure you get the most accurate soil insight, from the top to the button of your pot.
Do I need a plant monitor for every plant?
You don't need one for every plant. Most people get bundles to cover their trickiest plants first. Plant monitors can be moved between plants, so you can focus monitoring where it matters most at any given time.
How long does it take to learn about my plant?
SmartyPlants starts learning straight away. From the moment it's in the soil, the plant monitor 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.
