I will stick with 18/6 as i seen a lot of growers claiming to have better quality end product.If your c02 levels are usually elevated you could try 18/6 or 20/4. I don't really know, I do know that @automan runs his on 12/12 and does well.
The 96's have enough 660/730nm to not supplement unless you want to do End of Day treatments you may end up with excessive stretching.
My thoughts exactly about the far red in those qb's but now i know for sure thank you man you really helped me a lot!
