hey im here, thought i was already subbed, guess not, but now i am, LoL. cant help you with the smell, i dont have to worry about that, but some use ona gel or get a carbon filter system. one thing though, dont count this time as flowering, you are just on 12/12 now to make them start flowering. start counting flowering weeks when they show sex or pistals on the females. males tend to show sex first on most strains.
