Back in my newbie days i used a few of them for veg and flower. They will work but i suggest several of them . Also look online for a flowering bulb for it somthing in the 2600-3000k range. I also think home depot and lowes have em for around the same price... 3-4 would work .If your gonna put out the money i would buy 1 big light. Or lowes has a 150 hps same shape as the floro. 1 150 hps and 1 of the 65watt cfl would be more ideal for a few plants..
