Don't know, except to say as low as possible.
 
I have one of those large silica gel canisters in my gun safe.  Don't know if it helps or not, but it makes me feel better.  Of course, before I used any kind of humidity control measures, I still never had any rust issues in storage, as I keep my guns well lubed and always do an oil wipedown after use.

When using a Goldenrod (or light bulb or similar), it's more important for the temperature to be slightly higher in the safe that in the outside, as that keeps moisture from condensing on the guns.

If you have wood stocked guns, you don't want the air in the safe to be too dry, or the wood can dry out and crack (depending on what it's finished with).

Humidity above 65% is a problem.  Typically, you want to keep the humidity below 65% to prevent pitting of your gun and rifle barrels. If you get below 30% wood stocks may crack.
 
Dessicant bags keep moisture absorbed and humidty down.
 
Golden rods raise the temperature a few degrees and prevent condensation from forming on the firearm.

About 50% or less is recommended.  However, the Grand Canyon Caverns are considered to be perfect for storage of all types of survival items, including weapons.

The Goldenrod is NOT your friend. Heating the air without removing the water vapor does more harm than good. When you heat the air, the water content in the air remains the same, except that the heat raises the kinetic energy of the electrons of both the water in the air and the metal on the guns, making the electron collisions more active, speeding up the reactionary corrosion process. I told my father about this years ago, but he didn't listen because he thought the makers of the Goldenrod must be smarter than a physics teacher. Now he regrets having a safe full of rusted guns. He cleaned them all up and placed silica gel canisters in his safe and he's been happy ever since. It comforting to see the canisters fill up regularly, because you know that water is not in the safe anymore. You could also get an electric dehumidifier, or move to AZ where nobody ever saw rust in their life.

Pick up a cheap little humidistat. I prefer to keep the humidity as low as possible and use wood treatment. I never had an issue with wood with no humidity.

I know a guy who's been in the safe tech business for over 20 years and he maintains 50% is optimal.

I've had a golden rod in my safe for over 30 years and no rust issues so it must be doing something right. Worst thing you can do to create rust is put them in the old style plastic cases.  After suffering some severe pitting on a blue 30-06 Remmington 70 about 30 yrs ago I dont case them any more for an extended period. My grandfather had a rifle and a couple of shotguns that stayed in the broom closet with no care and they held up fairly well better than that rifle in the plastic case. I have seen and reported some corrosion on some Army M9 pistols but I believe that was due to them not being cleaned and wiped down properly.  Our Glocks have the toughest finish on them of any firearm I have ever seen - out in the rain and snow not wiped down and no rust issues over the last 10 years.
