Description

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).

The  reason plants need CO2 is to produce longer chain carbon compounds also  known as photosynthetic intermediates. Photosynthetic intermediates  includes compounds such as ribulose 1,5-bisphosphate, and  2-carboxy-3-keto-D-arabinitol 1,5 bisphosphate. Although the names are  complicated, the structures are quite simple (5 carbon chains). Flourish  Excel does not contain these specific compounds per se, but one that is  quite similar. By dosing with Flourish Excel you bypass the involvement  of CO2 and introduce the already finished, structurally similar  compounds. It is in its structural similarity that Flourish Excel is  able to be utilized in the carbon chain building process of  photosynthesis. Simple chemical or enzymatic steps can easily convert it  to any one to any one of the above named compounds (or a variety of  others).
