Masking the smell/ Determining the Strain.

I have recently got hold of a few seeds from a dime my cousin gave me. I have no clue what kind of seed it is, because I have like 4 types of marijuana on me right now. It is either Fire, Orange Kush, or Purp. Do these smell really bad during flowering?I found the seeds while rolling a joint, so that's why I have no clue what it is. Help would be appreciated. It is going to be an indoor grow, and is going to start as soon as I get a fan.

Get a charcoal canister and forget about it.
