What Does Full Sun Or Partial Shade Mean?

To judge if a plant got enough light, need to integrate a whole day's PAR. Is the Lux Function of 4-in-1 soil moisture meters useful? No! LUX is for the human eye's vision, rather than the photons that are useful for plants. The AH-20Plus can help you determine whether the plants have received enough photons throughout the whole day. Test the total mol of sunlight photons received per square meters for a day. Can help you to know whether the plants have received enough photons throughout the whole day. 15-20mol means 4-6hours. Record the Daily Light Integral(DLI) datas for each of 10 consecutive days. Accurately. Calibrate every dli meter rigourously in our factory. Already set the time according to UTC8 | UTC7 in our factory. No need to turn on | off the meter. Just use it once you got the meter.
