this wheat and barley grass juice thing is an expensive  joke . you will be
better off chewing some true freshlly harvested  wild grasses then spitting
out the fibers  ( couch grass taste good But all the fleshhy kinds are
good ) or juice them if you prefer . barley and wheat can't compare
nutritionally with wild grasses and powdering them  makes then even less
beneficial .

it will meet my need for life servicing activity. i am feeling disapointed
and scared  by all this energy,  economical means and ressources spent in
producing useless things when there is so much more important work to do to
makes sure our earth  continue to support us and all our relatives .
