4. Probably not.. Sativa's usually get pretty big and are not recommended for indoor growing in most cases

edit: Do some research on sativa dominant strains.. you may be able to find a few hybrids that are small enough to grow indoors... They do typically take quite a bit longer to flower as well.. so keep that in mind when choosing a strain.. sativas are usually 10-14 week flower.. inducas are usually 7 -10 week flower...

Well, sativas can only be run indoors in most of the world. I grow plenty of sativas indoors, Super Silver Haze, Neville's Haze, AK-47 sativa dominant phenos etc.
