Just been doing the same shit.
Added the top part of the box because the lights were starting to burn the plants. I also stopped LSTing because the plants are soooooooo bushy already. I did some timming to let light get to the more important nodes under the foliage. I also think I'm dealing with a few different strains here. Some of the leaves are most definitely indica, but others have thin leaves and seem like they might be a cross but more sativa dominant. I guess we'll see. Still can't figure out the pre-flowering thing, so I don't know what the plants will be so I don't want to transplant them. I'm going out of town this week, so I'll have a friend take care of them, and when I get back I'm going to start 12/12.

So here are some pics:
