No, you will not get dense buds with just blue light. If you are going to use CFLs for flowering at least get a 3000k light which is closer to red spectrum(daylight). 40 Acres uses a metal halide bulb which is a high intensity discharge light. It's expensive and puts out more heat then CFLs.
Yeah im restricted to a closet with NO ventilation..
.
I wouldnt want the light peeling the paint off the walls as well as killing my plants..
I was just wonering cause I was reading See More Buds book, and he didnt specify whether he switched his lights to red spectrum when he forced them into flowering at day 16.
I just assumed you might be able to do the job with the blues..
