A fan is not a bad idea, although technically you could probably do without it. Remember efficiency goes up slightly as temps go down.
You could add some 630nm reds, but the jury is still out on whether there is much to be gained from that.
If you haven't done it already, I would recommend considering building a far red flower initiator for this light.
i have been watching the flower intiating threads..
i have always used onset of flower 36 hrs darkness and it sees to work..not that early onset flowering by aday or so mattermuch for me.
unless you are meaning that the flower intiating is for flower mass..
