pc grow box

hi,
i just improved my old grow box. this 1 now has 2 23w cfl bulbs, 2 intake fans and 1 exhaust fan and is powerd by a computer power supply. will this be enough to grow 2 mersh plants, if not will it be enough to grow 1? (i dnt no the strain, in the UK mersh is mersh) and i will use LST. how bad will my room smell when it buds and how can i controll the odour without a carbon filter?

Thanks in advance

depends on the strain.
some hardly smell at all..

Yeah,it all depends,sounds like your fans should be enough.You shouldnt need more than some spray to control 1-2 plants.
