LilSmitty, as DFW-Guy has stated, the more light the better you will grow. We had 7-8 of the 6500k/100 watt bulbs on our 3 feminised plants. Theey seemed to love it. Come time to flower, just start replacing 6500k bulbs with 2700k. Works great if it you space the change over the whole week, like 7 bulbs over 7 days.
