FIM, LST and supercropping all will help you keep them under control alone or in combination.
There is no such thing as a CB plant that cant be harnessed to grow indoors in a decent space. Say, 2*2*5 and whatever you grow you can make it happen.
Some strains will just take more work and care than others.
