The carbon is derived from polycycloglutaracetal. Yes, the name is a 
mouthful ;-) but what it does is (as the description says above) act 
as a structurally simple organic carbon source for the plants by 
providing a carbon skeleton that is structurally equivalent to common 
photosynthetic intermediates (i.e. the stuff the plant makes from the 
CO2 it uses).

Information on both products should be up on our website by this 
afternoon as both are shipping now.
