It appears the Zinc Sulphate gives thinner roots but more of them. I have been testing it for some time. The Root Enhance gives thicker roots but less of them. At $9.99 for 4lbs of Greenwaybiotech Zinc Sulphate, its almost a lifetime supply, I will be sticking with it. You could also add it to your favorite booster, Rapid Start, Voodoo Juice ect, some which are loaded with zinc on the msds.
I also changed my dose to 1/8 tsp per gallon.
