they dont put off as many lumens as a hps bulb does for how much energy they use, much worse lumen per watt ratio. they have a broader spectrum yes, but most of it goes into white light and other unused specturm that just confuses the plant


plant want a mimic of nature

in oct is the suns color specturm white and blue? or yellow ornage and red?

hps is best for flowering
