I'm trying to provide my houseplants with as much natural light as possible inside my 2nd floor apartment.
I have 2 large bay windows that face north, and can put my plants directly by the window/on the sill. Here they're very close to the window but almost never get direct sunlight, due to facing north.
I could instead put plants in rooms with a large east or west facing window, where they'd have access to more direct light depending on the time of day, but in each case the plants would need to be significantly farther away from the window itself (6-9ft).
Does anyone know which would offer more/better light to my plants? I'm sure there are other factors to consider (my latitude, size of window, perhaps even paint color/reflective surfaces in room) but I'm curious if there's a more general principle/formula at play, with proximity to window trumping light direction or the other way around.
Would an exposure/light meter help me figure this out?
