Grow Light Meter: PPFD PAR DLI

About Grow Light Meter: PPFD PAR DLI

Are your plants getting enough light? Grow Light Meter turns your phone into a simple light meter for indoor gardening, so you can check whether a windowsill, shelf or grow light is bright enough for your plants to thrive.Point your phone at the spot where a plant sits and get an instant reading of light intensity, estimated in PPFD (the light plants actually use), with PAR and a daily DLI estimate so you know how much light your plants receive over a full day.WHAT YOU GET• PPFD reading — see the photosynthetic photon flux density at plant level, the number that really matters for growth.• PAR & lux — view photosynthetically active radiation and raw lux side by side.• DLI estimate — turn light intensity plus your daily light hours into a Daily Light Integral, the total light your plant gets each day.• Plant targets — compare your reading against typical needs for low-light foliage, houseplants, herbs, seedlings and high-light fruiting crops.• Find the bright spots — sweep around a room to discover where light is strong and where plants will struggle.WHO IT'S FORHouseplant lovers, indoor gardeners, hydroponics and grow-tent growers, seed starters, and anyone setting up LED grow lights who wants to place plants and lamps with confidence.A NOTE ON ACCURACYReadings are an estimate from your phone's ambient light sensor and camera, not a lab-grade quantum PAR meter. Use them to compare spots, position grow lights and spot dark corners — not for precise scientific calibration. Results vary by device.
