If you are not using HID lighting (which you are not.. correct?), you have nothing to worry about.. I would keep those fluorescents as close as possible to your plants.. As long as you have good air flow in your grow room, those lights can be less than 1 inch from your foilage.. actually, they should be less than 1 inch from your foliage..


I like your picture and the simplicity of your grow set up is awesome.. KUDOS to you!!!
