The Orchid Archive is a valuable resource on many subjects. For
those who are unfamiliar with using this archive, try typing 'Peter
Rowe and Prips flux' into the search box, select 'Orchid Archives -
Entire' from the drop down menu and be prepared to be amazed at the
volume of info available and how many times Peter has been faithful
in repeatedly sharing his knowledge on this one subject alone.
Thanks to Peter and all of the contributors who are helping us with
their good efforts!
