How much ginger should I add?

[dnr]

I am going to try for a ginger, lime and honey added to 3 gallons in secondary.
I'm going to test and think slice 1 whole lime and add about 4 oz honey. I am just going for a light flavor.
Any idea how much fresh ginger to add?
I'm going to bring this all to a boil in a little water to avoid infections.

Thanks.

Fresh ginger will not impart much flavor at all if not boiled. It also is dependent of the root itself. Some are more potent than others. I would boil up a batch and add it to taste.
