I am growing in a little room under my bed. I currently have 5 plants that successfully sprouted and are about 2-3 inches high. I have a 75 watt grow light i got a wal mart for 10 bucks ant they seem to like it. Nice and green and grow alot eeach day.Do i have to up the wattage when they get bigger?
You should have about 40-50 watts of HID lighting per square foot I should imagine a 400 watt would be more than ample for your grow
