hey there . I am a first time grower and like most I have been a worry wort about everything and I just wanted to tell you thanks for putting some of my fears to rest mainly concerning your source of light being just the one bulb and still having the amazing results you have had. I too am using floros ( 5 CFLs three 2700 lums and two 2900s. one 2` tube . and one 1` the two footer is red and the one footer is blue) and was originally worried about the strenght but as I said you put those fears to rest and gave me some confedience as well. congrats on your grow and further good luck man!!
