i beg to differ... loads of peeps use hps for the whole grow with ample success. i don't but i have friend who do. truthfully, their plants look better than mine!

to answer you q, yes it would work for two in a small reflective lined cab, but i would suggest you get another, or some cfl's. just because, ya know?

love, kp
