i would get them started and transplanted into 4" pots then flip to 12 /12 not sure how autos work but i think LST for you is the way to go as well get a sheet of ply wood or what ever screw in a handle so you can pul them out from under bed to water etc
your not goin to get huge buds but you should get some as well for lighting i think you will be fine hell look at my clones growing under florous
