I have had my tubes for over 6 months now and have read in many places that supposedly you should change the bulbs every 6-12 months for optimum plant growth because the power of them faded and your plants will notice the difference and that it could even induce algae because the tubes are worn out, even after only 6 months.
How true is this? what are peoples thoughts on this one?
