u would need to run a cool tube and vent out in order to keep the heat down inside the tv
and the speakes would have to pretty big to flower a decent size plant
but good luck with it
if u choose soil, ignore the first reply about miracle grow.
go to a local hydro store and get fox farm ocean forest or roots organic, just to name a few.
you;d have to put a noticeable amount of hair in a dime bag to gain any weight. no one does that.
it was probably just some hair that got into your sack.
its also about how u grow it, dont assume your going to be able to have the same yield as someone else
but i would try any sativa cause the indicas i've done it with just stay too small(super silver haze worked para mi amigo)
