i always flower with a 75%hps and 25%mh

i also drop nighttime temps the last week
HighTillIDie Reviewed by HighTillIDie on . increasing the thc trichome content i read in the latest cannabis culture ask ed section that if you switch to a mh in the last weeks of flowering you can increase your thc trichome content because mh produce more UVB rays than HPS. does anyone do this or know about this?
