it's not an issue of 'lumens', it is the lamp's specific color-temperature rating, that determines the better flowering characteristics ... in other words, the orange-ish hue of a HPS lamp, mimics the reddening of the light-waves from the late-Summer/Fall sun going down ... the spectrum shifts as it enters the earth's atmosphere at an angle ,,, 'blue' for vegging, 'red' for flowering ... mixing the two is fine, also ... :smokin:
