hi im about to start flower and i want to add a spare 400w to my setup thats already using a 1000w hps to increase yeild on my plants in a 4x4 flood table . is this ok ? i know its over kill but would like to use more light , cost and hydro is no issue here . the only way i wont add it if its gonna harm my plants in anyway , like light poisioning or something . thanks all
