There is huge debate out there on this subject, but the views are like night and day, flushing is either beneficial to your crop, or it isn't, there's no in-between, just like everything else on the subject, I suppose the only way one can truly know is to try it all and see what works for you, every grow is different after all. I grow for personal use, I don't know about you, but I don't like weed that tastes like chemicals, iv smoked it before and its nasty!
