no like in the greenhouse videos or that huge cave grow in tennesee the lights are built in to the roof of the room, plus in all these big grows i keep seeing full on budding plants under halides....not that im hating on halides just wondering if there is some advantage im missing out on
 
or if you guys notice when you take pictures under a hps the colors are skewed because of all the red and yellow light hps's are throwing out so I think they switch out the bulbs temporarily while shooting to get better picture but they
 
the LIFTED THE LIGHTS in the tennessee cave videos... and, if youre camera settings ar right...hps will ook white or blue (
