Don't do it! I made the exact same mistake and I killed a few plants, easily and quickly before finally figuring it out. Luckily my spot is close and they let me exchange it.
Not sure if it was grow big or not, I believe so, but I had a very bad experience with it. Don't bother e-mailing fox farm, they didn't respond to several I sent on the subject. It might have been Big Bloom, but either way, I would recommend against it.
Good luck
