Lightbulbs with a higher lumen rating work better, yes. And the best lighting for vegetative growth is one of higher kelvin rating --- as in, if it's daylight spectrum [ 6500k, I presume on those bulbs ], it would be better than say, the color temperature produced by a warm white bulb [ 2700k - 3000k ]. The higher color temperature will promote bushier growth and slow internodal spacing drastically.
Kush Over Reviewed by Kush Over on . Flourescent lighting and lumens question... A question regardiing those 4-foot flourescent tubes...Manufacturers sell them labeled with stuff like "soft white", "natural daylight", and any other kinds of adjectives. These bulbs are also labeled with the amount of lumens it puts out. My question: what lightbulbs work best for vegging? Lightbulubs with a higher lumen output? Rating: 5
