Flourish Excel is a source of bioavailable organic carbon. 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, which is more easily utilized by plants than ferric iron.
