Don't want the big girl to grow into the lights! Keep us updated as to how its going and good luck. And as far as it hurting the little plant, It will be fine, you will just have a nice short stubby plant.

Thanks for all your help i am going to change the light today to 12/12 and in a week or two i will put new pics on this thread and let you know how flowering is going.
