Generally speaking, the longer film is in the developer, the larger the grain will appear. This is why developers like HC-110A . . . for increased grain you could use the weaker dilution "B" of HC-110, or D76. The added development time will result in increased grain.
If you want a crunchy grain effect, try a method called reticulation. In this method, the developer is chilled, then when a warmed stop bath solution is applied in the next step of the process, the effect is similar to pouring hot water on a frozen windshield; the emulsion base cracks. These micro cracks yield a very cool effect.
Thank you for your detailed post! Interesting that you should mention HC-110 . . . back in the college photo lab, although I remember using HC110 (I think, 'B') quite often, mostly for 4x5, I always seemed to return to good ole' D76 for 35mm. The school had a densitometer, and I was nearly always able to get my D76 negs, spot-on. I later switched to the then, "illegal" formulation of Rodinal. I probably should've more aptly titled this thread, "favorite black and white film developers."

Now THAT sounds interesting! Thank you for sharing that technique!
