I have started spraying my plants with colloidal silver twice a day, one spray before the lights go on and one spray before the lights go out. I plan to switch to 12/12 in a couple of days my only problem is that the lights go out at 6am and don't come back till 6pm, I work most afternoons and I don't wake up till well after the lights go out and obviously, I can't open the tent to spray at 9am because the plants won't get total darkness. Can I get away with spraying once a day? My silver is 50ppm
