You definetly need to move them floros closer like 1 to 2 inches away and you need at least 80 watts for floros for a ok harvest. And for the halogen they suck get your self either hps or mh or even more floros you need lots and lots more wattage than 8 watts. Ive found 40 watt sun stick floros pretty good and only 6 american dollars a piece.The more wattage the more bigger and fatter buds the higher you get band dont be scared to put floros close.But change with hps or mh maybe to around 15 to 20 inches away with thse depending watts.Hopefully this will help.Peace and keep on growing.
