I meant more specifically which bulbs you were using. Mine is coming with an earth grow which is 90k lumens, 2.2k color/temp which I'm fine with, but I'm trying to figure out if I should get a different one and use that as a spare. From what I've read I need to replace them every few months to ensure maximum lumen output, so should I just stock up on the $30 90k lumen output lights?

My veg is still going to be pure CFL, but I've got the 600w plus 8 42w 2700's in flower. This should produce roughly 115k lumens for my flower stage in a 2x4 footprint (LOL) talk about excessive.
