Finding good seed at a good price can be difficult.I have had good luck with hard red winter wheat seed from wheatgrassman.com.I get my barley seed from wheatgra SSKI ts.com."Sprouting grade seed"is very expensive due to testing for microbial and germination issues.If your just growing for grass juice you can purchase the cheaper seed in bulk and keep your costs down.If your growing for food than sprouting grade is worth the extra money for piece of mind.Good luck and happy growing!!
