High John,

I would not grow it if I were you as once you have planted it you can not
get rid of it. The only way I believe is to cut off the stems just above the
ground, and pour roundup into the cut stems, which are hollow. this has to
be done quite a few times as the roots are very deep. Hope this helps you.

I am looking for a cheap form of japanese knotweed; for the
resveratrol

content, which is supposed to slow aging. Anyone growing this for
food

purpose's, any advice would be appreciated.

Not really recomended to grow as below taken from Wiki:

It can be found in 39 of the 50 United States (PUSDA) and in six provinces
in Canada. The species is also common in Europe. In the U.K. it was made
illegal to spread Japanese knotweed by the Wildlife and Countryside Act
1981, and it is listed by the World Conservation Union as one of the
world's 100 worst invasive species.[4] In the U.S.A. it is listed as an
invasive weed in Ohio, Vermont, Virginia, New York, Alaska, Pennsylvania
and Washington state
