I need help setting up my first grow room. i have a cubbard about 2.5 feet high 1.5 deep and 3 feet wide, is this do-able to grow. it has a 18" tube light at the top. what else do i need to grow. i also have a pretty big closet and a lot of space in my room, would the cubbard be the best bet if im trying to keep it hidden.
