well im growing in a bit bigger space then you.. but im using Flos. now for veg and for budding (along with 120w MH). from what i have read from other growers.. they perfer T5's over anything. you have the right wattage for the space.. its just that the flos aren't as effecient as HPS goes (in the specturm of light) with making buds denser and bigger.:smokin:
