Mike, we have a regent injection tank with "MOST" of its plumbing sittin in our shed unused for the last three years.  Used it one year, and traded the planter out from underneath it. 

The twelve rows we can't help ya out on.

Know nuthing about force, but regent has kept our corn standing like a broomsticks for the last four years.  We have the green rw beetles, not the brown ones up here, so far.

Mail me if ya want a look-C.
