Caution using molasses in Hydro, can get pretty gunked up...

Most Nutes for Hydro have a carb substitute or you can buy a additive that dose that will not clog the system. All depends on your system type, some say they have no problem running molasses...

There are three types of molasses, light, medium and dark ( blackstrap ), the light and medium are easier on the hydro system but the blackstrap is the best for plants.

If I were going to run blackstrap in my hydro I would start out at 3ml per gallon and see how it goes from there...
