I used miracle grow ferts and mg soil because it was very available at the time in Sept.2005. Germinated 18 out 20 seeds in it, 13 out 18 female. I used 1/4 strenght per quart water and added root stimulater after each transplant. 13 plants is alot for one 400hps in a closet. For 60 days of flowering I did not have room in closet for that many plants, so I rotated half every 12 hours. WHEW,that was a lot of work! but it was worth it. 30 mason jars of the best weed I ever had. First grow,following the mainstream advice, of the masters.
