How many hours should you run your lights?

I dose for potassium, plantex, and nitrate in the morning before the lights came on and one of the plants looks like it grew today. So did the cynobacteria. Did the nutrients bottom out again should I try uping my dose?
 
if you were getting good results with your plants with what you were dosing before, then dose the same way. i really don't think the nutrients are the cause of the bacteria. set your lights to run for 8 to 10 hours. and try starting a new thread on cyanobacteria and see what others think. you may not get much feedback since we have gotten a little.........:topic:
