i was reading some of the archives (some great stuff there, thankx to the
correspondents and organizers :-))

i noticed a suggestion to mix lemon juice with the green juice ...

well i came to grass-juice via Ann Wigmore, who did quite a bit of research
about it, and is well worth reading.
Some of the findings were

(1)   that citrus juice destroyed some part of the goodness of the juice.

(2)  the grass-juice began to deteriorate immediately it was expressed from
the leaf, and should be consumed within 15 minutes at most.

(3)  it is ok to chew the grass instead of juicing.

Hashigawa of GreenMagma(tm) and BarleyGreen(tm) fame found that
(4)  the leaves should be pressed on cutting (within 2 hours if protected, i
believe),

MyOwn experience is that the juice (i much prefer barley juice than
Wheat-grass juice) tastes a _wholeLot_ better if grown in high-quality
"organic" soil in the sun, with say one-inch (25.4mm) spacing or so between
seeds.  if grown outside, the plot requires protection from heavy rain,
slugs and snails, dogs and cats, and whatever else that messes it up...
local rules apply!!

is it worth all the trouble? at present i am not a great gardener.  if i
grow something, this stuff comes first cos i can buy most foods, but not
barley-grass of the quality i usually grow :-))

i don't know if all this has already been said, but its such a good food
that it's worth the risk.

regards to all,
