I don't know how tall they are. A couple were snapped off so those are shorter. A few are "S" shaped and those are the bigger plants. The shorter plants may be 10" tall?

Maybe it's a optical illusion, but looking from the top the horizontal plane is pretty green and dense already. The footprint of the twelve pails as close to touch is 48" x 32". I feel that the one 400 Watt HPS is stretched as it is to cover that area and as the plants grow taller the light may not penetrate to all the bud sites. I really didn't think that I'd be finishing all the plants when I started. I'm not used to having 100% healthy females.
I have the 2' x 4' four tube T5 for side lighting and will have to use a couple of CFLs or a 4' florescent to add light to the other side. I've grown experimenting with lots of ideas, this grow is diff as I'm not FIM or cropping at all, just LST. I don't want to trim fan leaves at this time. I did trim quite a bit of the bottom branches, as I've found this effective.
