If you know that the macro and micro nutrients are in ample supply, and 
that CO2 is in good supply, I don't know what that leaves but the 
lights. I find the way that fluorescent bulbs deteriorate is insidious 
because it is very slow. It is never perceived until one puts a new bulb 
next to an old one. You might have only half your original light output, 
or even worse.
