About WindowPlant Lab

WindowPlant Lab helps apartment growers answer a deceptively simple question: where should this plant go? Window direction matters, but so do distance, nearby buildings, trees, balconies, and the shape of the room. Our tools bring those details together so you can make a better first choice without buying specialist equipment.

The advice here is designed to be practical rather than absolute. A calculator cannot see your apartment, and two east-facing windows can behave very differently. Treat each recommendation as a sensible starting point, then let new growth, soil drying time, and changes in the leaves tell you whether the plant is comfortable.

What you’ll find here

• Simple tools for estimating window light and choosing a starting distance.
• Placement guides for common apartment window directions and conditions.
• Checklists that help you spot a poor location before a plant begins to decline.

Our approach

We focus on decisions you can actually make: move the pot closer, filter intense sun, choose a more tolerant plant, or add a grow light when natural light is not enough. We avoid miracle fixes and false precision. When a recommendation depends on conditions we cannot know, we say so.

WindowPlant Lab is an independent, evolving project. If something feels unclear or a tool misses a common room setup, that is useful feedback—and a good reason for us to improve it.
