the problem your gonna run into in such a small space is headroom
can you fit an array of lights,a good exhaust fan, and the container the plant is going to go in as well as the plant? another foot or 2 would help tremendously
as far as your strain question is concerned i would go with a well lst'd non-lowryder strain.
any lowryder i've smoked has not been up to my potency standards, not to mention the fact that i can't hardly stand a sativa high.
