Seriously depressing, there is a search button for these reasons sticky. I guess Ill educate you. An HPS light is a High Pressure sodium light, they put out red light arrays wich is better for flowering, this is 1 of the 2 HID lights. The other is MH, these put out blue light arrays wich are generally better for vegatation, correct me if Im wrong. Im not sure if Red/blue is the color, Im almost 98% on the money but if Im not, feel free to correct boys.
