I think CFL bulbs are bad for plant growth.
I don't have any evidence to prove that CFL bulbs are bad for plant growth, but only personal experience. On my 10 gallon fish tank, I was using 2x13 watt CFL Phillips bulbs, and I kept getting brown diatoms. Then, I upgraded to 2x15 watt bulbs, and I still kept getting brown diatoms. I was wondering if any of you think that CFL bulbs are the culprit for brown diatoms? I also want to state that my new Finnex LED lights are giving me better plant growth than the CFL bulbs.
