Hey thanks, which is more effective during veg, 6500's or 5000K . I was looking at a chart and chlorophyll activity is at it's highest when exposed to 5600K spectrum? Can you back that up at all? Anyone can make a chart.

Seems this thread never got an answer. 6500k is best for veg. Although had a hard time finding them at the store. Ended up getting 5000k CFLs also.

I use a mix of 5000K 5500K 6000K and 6500K bulbs, all 25w to 27w, with a 2700K 42w bulb. I find day light bulbs to produce far stickier nugs during flowering than soft white bulbs. I think the whole soft white for flowering thing is more theory than practice. Try it for yourself, but I stick with day light bulbs the whole way through after trying both methods.
