Rooms are microclimates
Open Bloombi expecting it to sort your plants by species — monstera here, ferns there, cacti in a corner — and you'll notice it doesn't. It sorts by room. That's a deliberate choice, and this post is about why.
The room is the variable
Species tells you what a plant tolerates. The room tells you what it actually lives in. Two identical pothos plants — same nursery, bought the same day — will drink water at different rates if one is in a south-facing living room and the other is on top of a bookshelf in a north-facing bedroom. Not by a little. By a lot. The living-room pothos might want water every five days in July; the bookshelf pothos might go two weeks between drinks and still be happy.
That difference isn't about the plants. It's about the rooms.
What a room actually is
When I say "room," I don't mean four walls and a door. I mean a set of physical conditions:
- Light direction and intensity. A south window in the Northern Hemisphere is bright and long-hour in summer, shorter and gentler in winter. A north window is soft and steady year-round. An interior wall away from any window is basically low-light forever.
- Humidity. Bathrooms and kitchens run humid because of showers and boiling pasta. Bedrooms in winter, with the radiator on, run bone-dry. That difference is often 30–40% relative humidity — a big deal for a plant that evolved in a rainforest.
- Temperature swings. A plant on a windowsill feels every cold night in January. A plant a metre inside the room doesn't.
- Air movement. Kitchens have doors opening constantly. A study nobody enters is still air.
None of this is about the plant. All of it changes what the plant needs from you.
Why "by room" beats "by species" as an organizing principle
You could organize an app by species — some do. It's cleaner in the database: every monstera gets the same schedule, done. The problem is that it's a lie the moment your monstera goes home with you. Your monstera doesn't live in "a species." It lives in your kitchen, or your bathroom, or your east-facing window — and that's what determines whether last week's watering was enough.
By putting rooms first, I'm asking you to look at the actual conditions your plants are in — and giving myself the information I need to adjust their schedules to those conditions, not to a generic "monstera in June" recipe.
What this enables
Right now, room information helps in two concrete ways:
- Smarter setup. When you add a plant to a low-light north corner, I can suggest a longer winter interval by default instead of assuming.
- Moves that mean something. If you rearrange things in the apartment and move a plant between rooms in-app, its care rhythm follows. You didn't just change its coordinates; you changed its climate.
What's coming: if I know your rooms, I can start suggesting which plants would actually be happy where. "You've got a bright south window with nothing on it — a jade plant would love that spot." Not right away, and not as a nag — but the foundation for that lives in how rooms are set up now.
What rooms don't do
Species still matters. A cactus in a humid bathroom is going to have a bad time regardless of how well I model that bathroom. Rooms tell me the conditions; species tells me the tolerance. Together they get you a schedule that actually fits.
If you've been lumping all your plants together in one "Home" room because it was faster to set up — no judgment, but you're leaving a lot on the table. Take five minutes, split them into where they actually live, and let me start using that.
The best care advice isn't universal. It's what this specific plant needs from you, in this specific spot, in this specific week of the year. That's what I'm trying to give you — and rooms are where the specifics start.
