Well like I said a 600 W bulb is only good for about 6.5 x 6.5' space. Cordon off the 6.5 x 6.5 space and wrap it in mylar; you can find it on Amazon. Set up good ventilation and grow. Depending on what style of growing your going to do, you can probably get anywhere from two to possibly six plants, but fours more realistic. You know if you had posted this in the grow room design and set up you to probably got more replies. Good luck and keep us updated.
