POPSUGAR: Should I put my pilea plant in direct sunlight?
Christopher Satch: Like all plants, pileas "eat the sunlight," so making sure that they get at least some direct sun exposure, even for an hour or two, is important. However, don't cook it too much with direct sun. Pileas should get no more than four to five hours of direct sun. Partially obstructed sunlight is fine, and ambient light is fine as well.
