Can I use a fine mesh nylon hop for grains?

[beeryalater]

Planning on starting my second brew tomorrow. It's a recipe kit from my LHBS - local being relative because I still have to order online. Just realized I only have fine mesh nylon hop bags. Will this be okay for the grains?

I understand the advantage of of using fine mesh over coarse for like pellet hops, but how important is it to have a bag specifically for grains? What's the difference?

Thanks!

You'll be good. Biab bags are all fine mesh.
