Free Plant Light Calculator

Tell us about your space and we'll suggest plants you can genuinely keep alive there.

How the Calculator Works

Window direction sets the intensity of light, while daily sun hours sets the duration. We match plants whose minimum needs are met by your space. A low-light plant (e.g. Snake Plant) will also be happy in a brighter spot, so it still appears — just keep it out of harsh, direct midday sun if it prefers shade.

Tips for Darker Homes

  • Rotate plants weekly so all sides reach the light.
  • Wipe leaves monthly so they absorb more available light.
  • Add a full-spectrum LED grow light for sun-lovers in dim rooms.
  • Group plants together to raise local humidity.
