I have a 150w hps 4 cfls on a custom fixture i made as well as a few other hanging cfls i was thinking that because the room is crazy hot. I was thinki g of cutting it from 24/7 to 16/8 til i flower to maybe help that a bit as well as shut off some if the lights from time to time. I have them in a closet where i just open the doors they have a fan on them so i may leave the window open for the night.thanks for answering haha as i said im reading through them but posted in hopes for a more direct answer to what my problem may be. Thanks !
