Grow from randoms seeds started 4/1/2013 - Can anyone help id type of strain/plant?

Hello all,
After a very long hiatus from growing I made the decision to start again using unidentified seeds from random prior smokes (If anyone can help to possible identify the strain please let me know). Well anyway I started 7 plants roughly on 4/1/2013 using a 250 watt HPS and Botanicare organic Fertilizer with a pro tea supplement. I switched over to the 12/12 cycle about a week ago and one plant had balls and the rest are females. The pics below range from 4/6/2013 to present. The biggest female is 20 inches tall and I am hoping I have enough room when these are in full bloom. If anyone can help me to possibly identify what type strain/plant that these may be would be greatly appreciated.

The one closest to the camera in photo 17. Looks like an Indica, reminds me of the last kush I did. That's all I know

I can't tell what strain they are, not sure if there's a way to determine that without lab testing. They all definitly look indica though, nice fat leaves. Sativa leaves tend to be long and skinny.

Well here we are on 5/7/2013 and roughly 40 days in. all of the plants are around 3 ft tall with the largest topping out at 4 ft. There are several buds everywhere and everything is shaping up nicely. My biggest issue to date has been the height of the largest plant which got a little close to the light and a few leaves were burned, but the bud formation still looks great. I hoping by Memorial day to reap what I have sown, but I think I will have to play that by eye. Let me know what you think of the latest pics that were taken today.

Hello all, I was able to get some pretty decent pics today of my progress to date. The plants all have some pretty decent bud activity and they have filled out a lot. My largest plant grew faster than expected and some leaves were burnt in the process...the bud itself is intact and still growing. I had to tie the stem to grow away from the light. The amount of budding is incredible to say the least. I underestimated the size of the actual grow and I will have to make some changes my time around.
