Autoflowering ?'s

Attitude had a huge sale a couple weeks ago & if u spent over a certain amount of money u got a bunch of great strains for free. I ended up ordering 5 Lowlife Automatic AK47 FEMINIZED Autoflowering Seeds. I got 1 free seed each of:

UFO #2 DNA Genetics Sharksbreath
UFO #1 DNA Rocklock Feminized
Magus Genetics Warlock Feminized
Magus Genetics Motavation Feminized
Serious Seeds Chronic Feminized
DNA Genetics Sour Cream Feminized
DNA Sour Kush Feminized
Paradise Sensi Star Female
Paradise Seeds Wappa Feminize

How exactly does autoflowring work? Do I just germinate the seed then put it under CFL's until its ready to either go outside or under the HPS? Do I just skip the Veg stage? Ill do some more research but do autoflowering plants usually yeild less then a normal growing plant? Is there anything special that needs to be done to them? Also, Attitude said the strains I got for free are some of their best. Do u guys know anything about them? Are they really anything special? All the plants Im growing now r in the W.W. family & its my 1st grow so Im still alittle ignorant.

9 free fem seeds? fuck me thats good is the offer still up?

o and with the autos they grow best under 20 hours on 4 hours off "light cycle" but yeah keep them under cfls for the first week then put em straight under the HID.

No, they only ran that special for like 3 days a couple weeks ago. I knew it was a good deal but wasnt sure about the brand or strains sinse I just started my 1st grow a couple months ago. I ordered my 1st set of seeds from Attitude and had a good expirience & when I saw that special I got more. I paid like $80 including secure guarenteed shipping for the 5 AK7 seeds. They always have specials tho, depending on how much you spend u get a certain amount of free seeds. Last time I ordered 21 seeds & got 5 free. Thanx for the help w/ the autoflowering. I know it prob depends on the strains but are the yeilds usually smaller cuz of a shorter growth process or doesnt that matter? Thanx again.
