Flourish Excel™ is a source of bioavailable organic carbon. All plants require a source of carbon.
 
This is typically obtained from CO2, but, may also be derived from simple organic compounds (such
 
as photosynthetic intermediates). The use of either CO2 injection or Flourish Excel™ does not
 
necessarily negate the use of the other. Because the processes of producing photosynthetic
 
intermediates and building onto them occur simultaneously, one can derive a substantial benefit
 
with the use of Flourish Excel™ either alone or in conjunction with CO2 . The combination is
 
particularly ideal for situations when continuing to add CO2 could result in dangerously low pH
 
levels. Flourish Excel™ also has iron reducing properties which promote the ferrous state of iron
 
(Fe+2), which is more easily utilized by plants than ferric iron (Fe+3).
