Your place gives it meaning.
The stoma draws on real local conditions. Its changing expression offers a biological read of your surroundings.
A biological field instrument. A continuing conversation.
Understand what you notice in your own place. What you tell STOMEL carries forward, so when you return, the conversation can build on what has happened.

01 / Start with something you noticed
THE STEWARD
“This spring I moved it where it gets afternoon shade”
STOMEL
That's a real adjustment. Shade cloth or a building casting shadow in the hottest part of the day — either way, you're buying yourself time.

The reply goes on to ask whether the change made a difference. The steward reports that the cilantro still bolted, but lasted noticeably longer. That reported result gives the conversation something to build on.
02 / There is more to the story
What you said. What you tried. What turned out differently. STOMEL is built to carry that context forward, so your next conversation can begin with more of your story.
The afternoon shade. The cilantro that keeps bolting. The details you bring make the conversation yours.
A plan may change. A location may need correcting. What you clarify should shape what comes next.
Time passing can make it worth asking how things went. Your account of the outcome is what gives the conversation an answer to build on.
03 / The real thing you grow
The afternoon shadow. The change in a leaf. The beginning of a pattern you recognize.
You see it before you reach for your phone. You understand a little more of what your place is telling you.
That is what STOMEL is here to cultivate: your capacity to see, reason, and care.
04 / Begin with your own place
A sentence. A photo. Something you noticed. That is enough to begin a conversation.
STOMEL is taking root. Join the waitlist to hear when you can begin.
No. Start with what you notice, whether it’s your first windowsill plant or a garden you’ve known for years. Your experience is the starting point.
Conversation is the medium. The purpose is to connect biology, the conditions of your place, and your experience over time — so your own ability to read the living world develops.
No. You choose whether to share it. Your ZIP code roots the stoma in local conditions and gives STOMEL context for your place and season. You can begin the conversation with an observation alone.
The stoma / Learn to read the living
The living green form is the app’s one enduring object. It has a purpose: to teach you to recognize how the living world responds to the conditions around you.
Give STOMEL your ZIP code and it takes root in your place. Local temperature, humidity, daylight, and changing weather shape its expression: how it breathes, glows, and moves.
The stoma draws on real local conditions. Its changing expression offers a biological read of your surroundings.
Notice how it changes. Ask STOMEL what you’re seeing and how that connects to conditions outside. Learning to read the instrument is part of learning to read your place.
“What is your stoma showing me today?”
Meet your plants with a little more understanding of the day they’re living through. Over time, that connection between conditions and living response becomes something you recognize yourself.
The illustration above introduces the idea. The instrument in the app responds to your locale after rooting; it is not a sensor reading an individual plant.
Actual stoma appearances from the founder’s August 28 certification sheet. These are recorded rest frames, not current local conditions.
The stoma has eleven physiological states, driven by real local physics. Seven express the rhythm of the day. Four respond when conditions demand something different.
The daily rhythm / Seven states
Night: conserving and repairing.
Before dawn: preparing for light.
Dawn: opening into the day.
Taking in carbon; moving water.
Conditions support vigorous exchange.
Afternoon: beginning to draw down.
Evening: closing and consolidating.
When conditions take precedence / Four states
Heat and dry air press for water conservation.
Heat and humidity make cooling difficult.
A pressure change signals an approaching transition.
Frost or freezing calls for protection.
The separate fallback shown in the certification sheet. It is not one of the eleven physiological states.
A guide to the instrument’s vocabulary, not a live reading of your locale. In the app, local physics determines its state and continuously shapes its expression.
