Why was the Lighting thread closed?
what are the coral farms doing.. I was reading that they use lower K lights for big time growth, then they put them under blue lights to colour them up for sale. the problem is I never caught what K the initial lights were but it sounded like they were HPS which is normaly around 3000K. but this could have just been what one person is doing and wrote it to sound like it was the norm also.. I am finding out that a lot of that goes on...
