OK I'm installing my mh fixtures today. I 3 different choices. I have 3 15000k bulbs 3 12000k bulbs and 2 20000k bulbs. I would like to use the 20k bulbs but can add a 15k bulbs like between the two then put my 3 t5ho actinic bulbs with it to increase the blue or should I space the 3 actinics out? Any suggestions?
