Full Boil

In Extract brewing I want to do a full boil  …  5 gallons.  Do I have to make any adjustments to the amount of hops?  Timing with the Hops?     Thanks

A rule of thumb is to go down about 25% of your hops. So if you do an ounce, only do 3/4 oz.

Timing should be the same.

Do you have a recipe calculator? There’s always software like Promash or even some online calculators like tastybrew’s http://tastybrew.com/calculators/recipe.html to ease your recipe scaling.
