help with understand veg and flower with g8led led lights

I was always under the assumption that there was a switch to change it from veg to flower, I have two g8led 900 lights, ive read that adding a flowering 90 watt ufo (which I do have also) will make them think its time for them to flower, but is there a switch somewhere to change it, or is it an all in one and by adding the ufo, I can tell it to go into flower whenever I want it to? Im confused and was just hoping that someone knows more about this and help explain it, so I can understand it better, thanks

Your plants are not going to flower regardless of what light you use, until they go to 12 hrs with out light.

Your welcome, This is a good site with lots of knowledge, Be patient and someone will get to you.. in the meantime dont do anything drastic like over water (which means watering to frequently)

flower . your light spectrum you want more red 2200 to 4200 k . veg you want 4200 to 7500 k you can use the 2200 k in flower more common 2700k . but it will not start to flower until you start a 10/14 to 13/ 11 common 12/12 light on light off . a 18 or 24 hour under any color light even the 2200 it will not flower its the time change that makes them flower .
