The reason and only reason I ask is because I am using CFL's for a grow and the way I am applying the bulbs is like so: The first week is just one 42 watt CFL (2,700 lumens) The second week will be three 42 watt CFL's (8,100 lumens) And the third week all of the CFL's I am using will be in use. [Six 42 watt CFL's (16,200 lumens) From what I know a seedling shouldn't get more than just that one bulb at first, they are delicate. So I don't want to add too many bulbs onto her like I did my last seedling and kill her with too much light and/or heat. The question I am trying to ask is, how many sets of new growth does it take for a seedling to not be called a seedling anymore? How many sets of growth should she have when putting the 3 CFL's on her? And how many sets of growth for when I want to put the rest of them on her? Please I just want simple answers to the questions I have actually asked, not some random side tip, or your own story. Just answer it how I asked, please. Sorry, I am not trying to be a dick or rude, just tired of some of the answers I get on here that aren't even being referred to the questions I asked.
