mate it looks like %50 sativa %50 indica genetics. (because the leaves are not fat and not very thin)
at least i am so sure that it is not mostly indica. ( indicas have fat leaves )
it may also be %75 sativa, %25 indica...
and i cant say if it is in flowering stage or vegging phase. because the photo is not clear enough.
just as a guess, i could say i saw sth like it is in flowering stage because of that plant has blooming tops..
if you can see white pistils (hairs) on tops, it means it is in flowering stage.
if you grow it indoor method, use cool white bulbs for 18/6 hours of light shedule
if it is in flowering stage, use warm white ( yellowish ) bulbs for 12/12 hours of light shedule.
