Just let the pressure rise naturally, has worked for me. It is later in fermentation that pressure helps suppress esters, and lower pressure at the start will get more yeast growth.
You probably don't want to let the internal temperature get much above 70F, just think ale. 60-70F works well.
How to search this forum? Got me! So much to wade through.
One thing to note, when doing pressure fermentation I just ferment out, then crash and force carb the rest of the way. 15 psi at 70F isn't enough carbonation. And I figure the point with the method is to ferment the whole way warm, pressurized, and fast. I only spund to fully carbonate with beers cold fermented at atmospheric pressure. I know it is possible to combine the two, it's just not something I've tried to pull off. You'd have to catch just the right point in a fermentation that can go to FG in under 3 days to increase pressure to near 30 psi at around 70F. PITA.
