On a hard tail, do you put less air in the back wheel as you

125 psi

1. No
2. Optimal tire pressure depends on tire width, rider weight, and to a lesser extent, surface conditions and rider preference.

25psi is a good starting point.

That's not what I read on various mountain bike forums

Then what you read is wrong. Neither tyre should be pumped hard, but the rear carries greater weight and needs higher pressure and/or volume. Overinflating your front wheel just for the sake of having higher front pressure than back pressure would be retarded.
I run 1 bar front, 1.2 bar rear on my hardtail. 2.4" in pretend nominal size and 60mm on my verniers. I used to run 2.25" in front for the reasons discussed and might again. The volume is usefull in the back, but less so in the front where I have dampers.

If anything I'd have a little less pressure in front than in rear (this goes for mountain biking in general) but really just fill them to exactly the same
23psi if thin, 35psi if fat (thin and fat referring to you, not your tires)

>but less so in the front where I have dampers.
except most of your lateral handling happens on the front of the bike, where having lower pressure/larger contact patch aids traction

60psi on both, always, I ride on street
