Help?

First off, I am a 1st time grower so I was wondering if I should flower. It has been growing from seed for 32 days at 18/6 cycle using 4 26w 6500k and 4 26w 2700k cfls,(actually it was under an incadencent plant light for the first 2 1/2 weeks and then switched to the cfls.) and is 18inches tall. It is a white widow strain and I read they only reach about 36 inches. So by the time it finishes it should have reached full growth right? Can anyone give me some good advice of what I should do. Any and all advice would be greatly appreciated.Also do you think this is enough light for one plant to get good results?

flower that bitch

get a 150 hps and flower. it is hard to get really good results with cfls. you can get a good 150hps for about 80$ just look online.
