Light Levels. In photography, a light meter (more correctly an exposure meter) is used to determine the proper exposure for a photograph. Low - Minimum high level of 25-foot candles, preferred level of 75- 4.4 out of 5 stars 23. Succulents, Cacti, Croton, Crassula, Zebra Plant, Azalea In summary, low light plants will tolerate light levels in the range of 100 fc - 300 fc, but you might not see optimal growth.

Moisture Meter Instructions 1. Place the moisture meter halfway between the trunk and exterior of your pot. If a particular light source was very heavy in the violet and blue region the PAR meter, based on its calibration, would likely yield a higher uMol/M2-S based on its sunlight calibration assuming that some of that additional light energy from the blue must be red. 2. Likewise, there are many units for measuring light based on human eye sensitivity: foot-candles (ftc), lux, candela, and lumens. This easy-to-use tool will tell you how wet or dry your plants root system is. remember a plant by its scientific name, because some plants have many common names but only one scientific name.
