Still haven't read if you can use the grass if you have a mold problem. I am new to growing/using wheatgrass. I always have white puffy cloudlike mold near the bottom of my grass. Try spraying with citricide mixture, doesn't work. But the question is....can I drink the juice from the grass if I have seen mold?? I have been juicing for about a week, I rinse the grass off very good before I juice. Am I doing my body more harm than good by using this grass?
