Hey everyone. I started some broccoli,brussel sprout,cauliflower,and 4 different types of peppers in my greenhouse. I have a heating mat set at 75 degrees for bottom heat. I have them in regular plastic trays with plasic domes. I also have them under shop lights. I didnt know if im suppose to turn the lights on now or wait till they sprout.So thats my ? turn them on now, or wait a week,thanks,brandon
