We prefer a custom soiles mix without any wetting agent(chemical) or start up fertalizer(urea) found in most store bought mixes. And we amend out mix with Food grade sea kelp MEAL....not man made liquid. opur 8th year in Florida. Also we purify and filter our deep well water. Also PREFER hard red SPRING wheat....certified organc for sprouting(only cleaned 3 times compared to cereal or grain that is cleaned 4. LESS handling...Better! And we put our 4 SECRET ingridients on EVERY labelAnd the day that it is cut. We call our FRESHwheatgrass Premium wheatgrass for a reason. Correct me if I am wrong but I belive at this time only about 50 people in the ENTIRE United States grow FRESH wheatgrass for the public! Tere should be MANY more!
