I'm trying for the first time to grow to harvest under this T8 fixture. I've started plants under this light before but have always moved them outside. I have a T8 HO fixture with 6 bulbs and currently using 5000k bulbs. My question is what bulbs should I use when flowering? They have bulbs available in the 3000k range, should I go with 6 of the 3000k or should I keep some of the 5000k bulbs in there? I'd appreciate any help I can get.
