I have just recently began using grow lights to start my greens indoors and to continue to grow them indoors through the hot summer and winter, is my hope. How important is it to have a fan in the room with them? I did use a fan to start with when they were in the basement and I noticed white fuzzy growth on the soil but I have not used one upstairs where they will remain. I have not seen the white growth yet but do not know if that is next. Thank you. northern Illinois
