I am going to build a cool tube for a 400 watt bulb (one HPS, and one MN)...Will the glass degrade the output of the light? I have limited space (room to grow maybe 7 plants) I will have good ventilation, and I want the lighting to be the best it can. Will the 400w be enough? will it handle 7 plants or should I just get the 600 watt bulbs?
