they look good, but id get those out of the bottles, see thru is bad for the roots i believe. adding a couple more lights would be good. also go to a wal-mart and get some of that emergency blanket stuff, really really reflective, i bought some a couple of weeks ago and i can tell that my plants love it. 6 weeks old from seed....im pretty sure those are gonna get BIG. when in flower they double in size. i started flowering at about 12inches tall, and just today i measured again and im at 24inches tall, and just about to hit my 3rd week flowering. so yea look into getting those things and you should be good to go. oh yea id use about the same size pots for those, maybe a bit bigger just so the roots can stretch out a bit. but its all up to you, just get those other ones into pots
