since your name is the intensity of the sun..... have you tried growing
wheatgrass outdoors in the direct sunlight. After years of reading
the emails of this wheatgrass group, it seems conclusive that growing
wheatgrass outdoors in direct sunlight is the ONE strategy that handles
the mold problem, and allows anyone to drink several ounces of
wheatgrass at one time, feel great and have no "allergic" or negative
reactions....... (even those who formerly complained of feeling sick
before on regular indoor grown wheatgrass)........
