If you want big grain, change to a film that has larger grain. FP4 is
100asa, fine grain material. HP5+ and Tri-X are more appropriate for big
grain. I assume you also want sharp, big grain. Use a developer that
gives hi res grain like HC-110. dilution B. Push process using 5-10
degrees higher temp will also increase the grain size.
