The hybrid Dutch stuff is hungrier for nitrogen than typical heirlooms, so I ruled them out as being too much of a PITA. I suspect my hands will be full enough trying to bring some type of stable fertigation system on line.
However, it did get me to thinking about the requirements in general of hybrids versus heirlooms. If these Dutch super-modified, high production tomato engines require more nitrogen, would hybrids in general benefit?
