Foot∼Candle: (f.c.) A unit of measure of light intensity, based upon the illumination of one square foot of surface that is one foot away from a standard candle. One f.c. is roughly equivalent to 10 lux (0.093.f.c = 1 lux) This unit is obsolete in academia, havinf been replaced by photosynthetically active radiation. (PAR) units such as micromoles per square meter per second (umol m -2 sec -1), microeinsteins per square meter per second (uE m -2 sec -1), or watts per square meter (wm -2) The unit foot-candle is retained for this work because of its simplicity and because meters reading foot-candles are inexpensive and readily available.

It is mainly comprised of humus base, but have a lower molecular weight than humic acid, rendering them better for plant useage. Contains collodial minerals at a stabilization that is easier for the membranes and cells of plants to uptake and use. See PDF Document with more pertinent information on Fulvic Acid. Also used as a supplement for humans, but more often, humans use humic acid for this purpose.
