Dry hop question

[tpw]

I'm trying an IPA recipe I found on BeerSmith that calls for dry hopping. I've done this before at the last 3 days of secondary. This particular recipe calls for dry hopping with Centennial and Chinook at 0 days. How do I do this?

Without seeing the recipe, it is hard to know.  Since you found it on the BeerSmith recipe cloud, I would look it up and message the person who brewed it.

Failing that, I usually enter in 0 days when designing a recipe using dry hopping and then adjust the number of days when I actually brew and hop it, gauging the addition of the hops into the fermenter by when the active fermentation ends.
