ur not doing research.

You have told us nothing about how your growing or what kind of conditions they are living in. Things like temperatures, system design, ppm, ph, come on. The reason people are likely annoyed with you is because your asking questions already asked and easily found with some research. Not to mention that whatever picture you have in your mind for both your current room and whatever you want, is not something we can see. You'll have to do better at telling us what your looking at with actual numbers. "I have a light and it's really bright," doesn't usually get you the answers your looking for.

Are there better methods of growing? Yes. At least for lights, but since nobody has any idea how your growing then we cant tell you whether or not you can do better. Closets are great grow rooms, but you will want to do more in the HVAC category instead of just a couple pc fans. I can assure you at some point before you harvest you will want much bigger lights or more then what you have now.
