i soaked my seeds in distilled water for 24 hours with superthrive and have a 400 watt hps, i was wondering how far the light should be away from the plants, i will be just plopping them in the soil after the 24 hours is up, waiting for them to sprout and then placing them under the hps. i have heard 18 inches is the ideal distance, is this correct? thanks again, nugz
