The best seed I have found so far was at wheatgrassman.com.He is located in texas,shipping might be an issue.Whatgra SSKI ts.com gets there seed from a mill in collinston uhta.I am growing both this year,The texas seed produces 30% more than the uhta seed.If your going to juice the grass you might try a grow rack with shadecover.Direct sunlight is hard on wheatgrass.I have good luck with 4tier grow racks with 60% shadecovers in central ILL.Good luck and happy growing!!
