Hi guys, I'm sure this is not the first time this has been asked but I have tried to find information on it and had no luck in e-books or on these forums. I have 3 2700 45w bulbs that I am using for seedlings, and then I will switch these for 4 6400 45w bulbs for the later stages. My question is would it be beneficial to use all these bulbs the entire time? Is more light better, regardless of spectrum? I could use all of them at once, should I? thanks in advance.
