I have only ever grown autos, and the first thing i found was the estimated harvest time by the company is a load of crap, you usually have to add a week + and i used cfls for a very long time. When buying a cfl you cant go by equivilent watts, go for actual watts (the lower number) stick for watts between 20-30 and get the bulbs with as many lumen as possible, with autos you can use just 2700k bulbs and it will work fine, but for a nice healthy plants use some 6500k blue bulbs. And get as many as possible, i had 15 30w 1600 lumen, 2700k and 5, 30w 1400 lumen 6500k bulbs, growing sweet tooth auto, and it just wasnt enough, i had a smoke but nothing i could brag about, i have been using hps for 15 days and the difference in growth is out of this world. Get a microscope and as another grower said watch the trics, if you cang get one wait for 80 percent of hairs to change to red then chop. Hope this helps and remember to get ur lights 2 inches away.
