PointCast now has a houseplant learning lab. The point is not another list of plant names; it is a way to read the room your plants live in.
Start with light, then water, then air in the root zone. Most indoor plant problems get easier when you stop treating the leaf as the whole story and check the system: window direction, pot weight, drainage, soil structure, humidity, growth season, and leaf pattern.
The module includes eight lessons, twelve plant profiles, a symptom decoder, a care desk, and a JSON mirror for agents. It sits next to the El Segundo nature field guide as the indoor counterpart: outside we read dunes; inside we read pots.
