CFL distance to tops (did search) I have 12 cfls of various wattages (mostly blue spec for flowering) i am just wondering about the best distance to the plants.. i had them as close as possible .. maybe 1 1/2'' - 2'' but i noticed that it was just too hot and growth got to a point and was halted.. they are now about 10'' away will this be fine?
