Geo-climate growing recommendations
What might grow here?
Windowsill reads a place, direction, context and week, then returns edible plant recommendations with visible limits. It is not an oracle. It is a correctable public instrument.
Missing a plant? Start with the contribution guide. You can use ChatGPT to prepare a research pack, but sources and uncertainty must stay visible. Research packs do not automatically change the live plant count.
Start here
Three ways in.
Add a plant
Copy a prompt into ChatGPT, check the result, then send a research pack.
Build with the API
Use the public API for small tools, prototypes, teaching and experiments.
