What was the initial yield of juice in ounces?How was the taste and was the grass dark green and vibrant?Do you have pics. by any chance if so download them to the Image Gallery so we can see what your talking about.A second cutting is a waste of time with grass.The juice will be very bitter and the flat usually goes bad do to root binding/souring and mold overgrowth.Lift up the mat and check the roots for discoloring and the smell of souring is easy to detect as well.I have pics. of my barley grass in the Image Gallery in the photos section under grassmans sprouts.I will be starting my growings on in another week to ten days when the weather starts to cooperate.
