you cant really do a SOG in that small of a space, unless you want a really small one. SCROG is much better for smaller spaces, it gets the maximum yield out of a plant. Get a 165cfm exhaust blower for your light, itll work perfect. IF you want good reflection matter, paint ur area with flat white paint, foil and mylar are not worth the time. Keep good ventilation with fans in the grow area, and try to get outside air to flow nicely in and out of the grow box. Good luck!
