How intense light ppfd to expose various species to and for how long light intensity or rather how densely packed light is with photons is measured in micromoles per meter squared per second µmol m2 s.
It describes the number of photons of light within the photosynthetic waveband that an area of 1 sq meter receives per second.
Intense light has high ppfd and low intense light has low ppfd.
Plant light meter is the most important tool for indoor growers.
This is called ppfd photosynthetic photon flux density.

Very low to high uses the rear camera only intensity up to 100 000.
According to runkle 2006 the better unit of light intensity for studies involving plant responses is the μmol m 2 s 1.
Lack of light is the second most common cause of death of indoor plants after excessive watering.
The method we use is to hold the light meter as close to the leaves of the plant as possible with the sensor pointed away from the plant in the direction of the incoming light.

A klux is a 1000 lux and about 1 1 klux is the minimum light requirements for any plants for at least 12 hours per day to gain any benefit from fertilization.
A precision instrument that measures the light intensity in footcandles expressly for the purpose of plant care.
During bright daylight in a warm and sunny place the sun s ppfd.
If your plant is against a wall you can point the sensor against the wall to get an idea of how much light the back side of your plant is getting.
Equipped with the universal sensor probe capable of reading light at any angle or in any location.
Better light conditions will allow you to keep your plants healthy.
4 levels of intensity.
A light meter is used for environmental testing of light pollution determining proper lighting for photography and checking conditions for plant growth.
